Inflorescences of Cliffortia L. (Rosaceae) and related vegetative branch­ing patterns
Authors: Fellingham A. C. , Linder H. P.
Published: July 2015

The inflorescence construction of eight species, representative of the types found in the 119 species of the rosaceous genus Cliffortia L. is described, based on stereo microscopic examination of fresh and dried specimens, combined with extensive field observations. In its simplest form the inflorescence is a reduced short shoot, bearing a lateral ebracteate flower and a potentially viable apical bud. Variations in the basic structure can be in the number of flowers, the mix of the sexes of the flowers and the number and type of short shoots as primary, secondary and tertiary axes. A high incidence of structural plasticity of the inflorescence occurs. This can be either throughout the development of the inflorescence or only at the onset of the vegetative stage. These changes occur in the short shoot(s) constituting the axes of the inflorescence, causing either an increase in the length of the intemodes. apical proliferation of the axes or a combination of these two effects. A specific com­bination of changes is linked to a specific inflorescence type. The vegetative elements of the inflorescence thus modified, are retained as an integral part of the vegetative branching system, with extensive influence on the branching pattern. This can also result in the predominance of one sex over the other over time, so that an individual, initially of the one sex. can become one of the opposite sex by the end of the season. Erroneous interpretation of a single point in the process of sex change as if it is a permanent state of sexuality, led to the prev alent acceptance of dioecy as the norm for the genus. Monoecy with dichogamy (or herkogamy at inflorescence level) was observed in this genus, as in many other wind-pollinated taxa.

Two new species of Romulea (Iridaceae: Crocoideae) from the west­ ern Karoo, Northern Cape and notes on infrageneric classification and range extensions
Authors: Manning J. C. , Goldblatt P.
Published: July 2015

Two new species of Romulea are described from Northern Cape, raising the number of species in southern Africa to 76. R. collina J.C.Manning Goldblatl is endemic to the Hantamsberg near Calvinia. It is distinguished in subgenus Spatalanthus by its clumped habit, yellow flowers with dark markings in the throat, and short papery bracts. A re-examination of rela­tionships within the subgenus suggests that section Cruciatae is not monophyletic and it is accordingly no longer recog­nized as separate from section  Spatalanthus. R. eburnea J.C.Manning Goldblatt is a distinctive species of subgenus Spatalanthus from the Komsberg near Sutherland. It is distinguished by its golden yellow flowers with the apical third of the tepals coloured pale creamy apricot, bracts with broad, translucent margins and tips, and an unusually long perianth tube, 10-13 mm long.

Vegetation of high-altitude fens and restio marshlands of the Hottentots Holland Mountains, Western Cape, South Africa
Authors: Sieben E. J. J. , Boucher C. , Mucina L.
Published: July 2015

Seepages occurring at high altitudes in the Hottentots Holland Mountains (HHM) (Western Cape Province. South Africa) were subject to a phytosociological survey. Relevé sampling method and classification procedures of the floristic-sociological (Braun-Blanquet) approach as well as numerical data analyses (numerical classification and ordination) were used to reveal syn- taxonomic patterns and characterize the position of the syntaxa along major environmental gradients. Nine plant communities were recognized, three of which were classified as associations, following formal syntaxonomic and nomenclatural rules of the floristic-sociological approach Most of the studied mire communities were dominated by low-growing clonal restios (Restionaceae). whereas some consisted of other types of graminoids. The most important species determining the structure (and function) of the mire communities on sandstones of the HHM include restios Anthochortus crinalis, Chondropetalum deustum.C. mucronatum, Elegia intermedia. E. thyrsifera. Restio subtilis. R. purpurascens. cyperoids Epischoenus villosus. Ficinia argy-ropa, grasses Ehrharta setacea subsp. setacea. Pentameris hirtiglumis as well as shrubs Berzelia squarrosa. Cliffortia tricuspi- data. Erica intenallaris and Grubbia rosmarinifolia. Protea lacticolor and Restio perplexus dominate a rare shale band seep­age community. There are two major groups of communities—the fens (dominated by carpets of Anthochortus crinalis and other low-growing species) and the restio marshlands (mosaics of low tussocks of Restio subtilis and tall Chondropetalum mucrona­tum). The degree of soil (and water) minerotrophy was found to be the most important differentiating feature between the mire (fen and restio marshland) communities studied. The soils in the centre of mires were found to have high contents of peat and showed very little influence from the underlying sandstone. The soils along the mire margins had a greater admixture of mineral soil derived from the sandstone or shale bedrock.
Two new species of Asteraceae from Northern and Western Cape, South Africa and a new synonym
Authors: Manning J. C. , Goldblatt P.
Published: July 2015

We recognize two new species of Asteraceae from the winter rainfall belt of South Africa and reduce a third to synonomy.  Senecio speciosissimus sp. nov. has been confused with  S. coleophyllus Turcz. in the past but is distinguished by its taller stature, larger and more finely serrated leaves, and congested synflorescences containing (6-)l 5-40 flowerheads. The two species are also geographically separated:  S. speciosissimus occurs in the Hottentots Holland and Franschhoek Mountains of the southwestern Cape, whereas S.  coleophyllus is endemic to the Riviersonderend Mountains.  Chrysocoma hantamensis sp. nov. is a distinctive new species endemic to the Bokkeveld and Roggeveld Plateaus. It is distinguished by its resprouting habit. 3-5-fid leaves and large capitula, 12-15 mm in diameter, with lanceolate. 3-veined involucral bracts, the largest 9 - 1 0 x 2 mm. Investigation of the variation in leaf morphology of the two radiate species of Oncosiphon, O. africanum (PJ.Bergius) Kallersjo and  O. glabratum (Thunb.) Kallersjo. reveals that only one species can be maintained, and O. glabratum is accordingly reduced to synonomy in O. africanum.

Ovule-to-seed development in Dovyalis caffra (Salicaceae: Flacourtieae) with notes on the taxonomic significance of the extranucellar embryo sac
Authors: Steyn E. M. A. , Van Wyk A. E. , Smith G. F.
Published: July 2015

Dovyalis caffra (Hook.f. Harv.) Hook.f. is a widespread and horticulturally important southern African endemic. Here described, ovule-to-seed development represents the first embryological information on this genus of the tribe Flacourtieae, Salicaceae  sensu lato. Results are discussed in the light of data available on the embryology of the order Malpighiales in general and on the tribe Flacourtieae in particular. It is clear that Dovyalis E.Mey. ex Am. shares many characters with other members of the Flacourtieae. Ovules of D. caffra are anatropous. bitegmic and crassinucellate with both bisporic Allium- and monosporic Polygonum-type embryo sacs. One of the most characteristic embryological features of the tribe is the pres­ence of an unusual, extranucellar embryo sac that stretches halfway up into the micropyle. Since this extraordinary-shaped embryo sac also defines the embryo sacs of Salix L. and Populus L., it is suggested that the character provides strong sup­port for the proposed close phylogenetic link between tribes Flacourtieae and Saliceae of Salicaceae sensu lato.

Two new species of Nemesia (Scrophulariaceae) from southern Africa
Authors: Steiner K. E.
Published: July 2015

Two new annual species of Nemesia Vent, are described from southern Africa. N. williamsonii is characterized by bright orange flowers with an inflated yellow palate. It differs from the related N. maxii Hiern by having a spur that projects backwards, not downwards, and bracts that are lanceolate with a truncate base, not triangular or cordate. It is unusual for the genus in having dimorphic seeds.  N. williamsonii occurs almost exclusively in the Richtersveld. but has been collected in a few localities across the Orange River in southern Namibia. N. hemiptera is a delicate, wiry-stemmed annual with small white flowers. The flowers are characterized by a tiny nipple-like spur and a seed that is winged on onlv one side. N. hemiptera isendemic to the Kamiesberg from near Garies to Kamieskroon.
Notes on the systematics and nomenclature of Tritonia (Iridaceae: Crocoideae)
Authors: Goldblatt P. , Manning J. C.
Published: July 2015

Study of some early types of species now known to belong to the genus  Tritonia Ker Gaw l.. a member of Iridaceae. sub­family Crocoideae, comprising some 28 species of southern and south tropical Africa, has shown the need for some nomen- clatural adjustments. Ixia undulata Burm.f. (1768) is an earlier name for T. crispa (L.f.) Ker Gawl. based on Gladiolus crispus L.f. (1782) and the combination  T. undulata (Burm.f.) Baker must be used for the species, which is native to the western half of Western Cape, South Africa. The variety  T. crispa var. parx iflora is also reduced to synonymy. The type specimen of Ixia gladiolaris Lam. (1789), currently considered a synonym of Tritonia securigera (Aiton) Ker Gawl.. has flowers that lack the characteristic tooth-like ridges on the lower tepals of the latter, and corresponds closely to the eastern southern African  T.  lineata (Salisb.) Ker Gawl., based on Gladiolus lineatus Salisb. (1796). The new combination  T. gladiolaris (Lam.) Goldblatt J.C. Manning is made and  T. lineata is reduced to synonymy.  Montbretia lacerata and  Tritonia lacerata. erroneously regarded as synonyms of T. crispa, are combinations based on Gladiolus laceratus Burm.f., a species that remains unidenti­fied because no type is known and the description is too vague to permit its identification. Lastly, field studies have shown that the cnsped-leaved T. watermeveri is connected by a series of morphological intermediates to typical  T. securigera. which has straight leaves and identical flowers. The new combination  T. securigera subsp. watermeveri (L.Bolus) J.C.Manning Goldblatt is proposed for this taxon.

Can anthropogenic variables be used as threat proxies for South African plant richness?
Authors: Keith M. , Warren M.
Published: July 2015

Human demographic and socio-economic measures (anthropogenic variables) reflect the detrimental impact of humans on plant diversity globally. The Pretoria (PRE) Computerised Information System (PRECIS) of the South African National Biodiversity Institute (SANBI), provided three sets of South Afncan plant richness data, overall (OPR), endemic (EPR), and threatened (TPR), to investigate the relationships between richness and six anthropogenic variables. Spearman’s Rank order correlations, Kruskal Wallis Analysis of Variance (ANOVA) and Generalized Linear Models (GLZ) were used. Although all three plant richness measures were correlated with anthropogenic variables, individual anthropogenic variables contributed a small fraction to the explained variation in richness. Differences in spatial and temporal scaling of the datasets, or the response to another causal mechanism, may have contributed to this low explained variation. Because more variation was accounted for in OPR than EPR or TPR, OPR is a more suitable surrogate measure of plant biodiversity when investigating the anthropogenic variables used here. Average human density (HD), infrastructure (degree of urbanization and road cover) (LRU) and percentage land area transformed and degraded (LTD) were identified as useful surrogates of human impacts on OPR. LTD may be a more inclusive human impact measure when conducting analyses of human impacts using OPR. LTD includes the effects of urban expansion, road networks and other land transformation impacts, such as agriculture.
New species of Drimia (Hyacinthaceae: Urgineoideae) allied to Drimia marginata from Western and Northern Cape, South Africa
Authors: Manning J. C. , Goldblatt P.
Published: July 2015

Plants until now identified as Drimia marginata (Thunb.) Jessop on account of their leathery, oblong to elliptical leaves with thickened, cartilaginous margins and capitate inflorescences of campanulate flowers, are shown to comprise three sets of populations separable on leaf morphology, ecology and distribution. Typical D. marginata produces 1 (2) oblong, apiculate leaves with retrorsely-scabridulous margins and occurs in fine-grained clay soils on the Hantam and Roggeveld Plateaus. Plants from Namaqualand and the Richtersveld. described here as Drimia pulchromarginata J.C.Manning Goldblatt. occur in sandy or gravelly soils and produce 2 -4 , elliptical to suborbicular, apiculate leaves with an ornate, duplex margin: the dorsal surface bears a submarginal band of dense, velvety trichomes fringing the thickened, colliculate margin. A third series of populations from seasonally moist sandstones at higher altitude on the interior mountains of the West Coast produces2 or 3(4) narrowly oblong, obtuse leaves with a simple, papillate or colliculate margin and are recognized as D. ligulata J.C.Manning Goldblatt. A fourth taxon with a similar capitate inflorescence of campanulate flowers produces a solitary, subterete or subclavate leaf, elliptical in section. Recorded from scattered localities in the Northern and Western Cape', it is here described as D. vermiformis J.C.Manning Goldblatt.

Systematics of the southern African genus Ixia (Iridaceae). 1. The I. rapunculoides complex
Authors: Goldblatt P. , Manning J. C.
Published: July 2015

Field and laboratory investigation of the six varieties of Ixia rapunculoides Delile (recognized in the current revisions and flora accounts of this southern African genus of some 65 species) show that a revised taxonomy better reflects the biology of the complex. The complex is defined by the funnel-shaped perianth tube, filaments fully and anthers partly included in the perianth tube. Our conclusions indicate that  I. rapunculoides (currently var.  rapunculoides) is restricted to the western Karoo and has broad, leathery leaves, a short perianth tube, mostly 5.5-8.0 mm long, and half nodding blue-mauve flowers. Plants currently referred to I. rapunculoides var.  flaccida G.J.Lewis, include four sets of populations that we regard as two separate species. These are:  I. flaccida with small, short-tubed white- or pale blue-flushed flowers, sofl-textured leaves and corms with basal cormlets from the Olifants River Valley and nearby; and I. sobolifera from the Western and Little Karoo, which has linear leaves, nodding spikes and flowers and corms with stolons. We divide  I. sobolifera into three subspecies: subsp. carnea with pink flowers, is restricted to the Bokkeveld Plateau and nearby; subsp  sobolifera with slate-blue flowers occurs in the Klein Roggeveld and nearby; and subsp  albiflora with strongly scented white flowers occurs in the central Little Karoo. The taxon called  I. rapunculoides var.  namaquana (L.Bolus) G.J.Lewis, defined by a longer perianth tube, mostly 13-16 mm long, horizontally oriented, white, pale lilac or pink flowers and few-flowered lateral branchlets. is treated as I. namaquana, first described by H.M.L. Bolus in 1931. Plants referred to this taxon from south of its range at Hex River pass and nearby, however, have fully included anthers, a longer perianth tube. 16-20 mm. and ascending purple-pink flowers with a white cup and are referred to the new I. oxalidiflora. Two more varieties, I. rapunculoides var. subpendula G.J.Lewis and var. rigida sensu G.J.Lewis, which have upright flowers and distinctively branched stems are treated here as I. divaricata and I. contorta.  Plants in the past included in var.  rapunculoides from the Klein Roggeveld, south of the range of typical I. rapunculoides, have a longer perianth tube. 10-14 mm long, and attenuate, slightly lacerate. 5-veined. dry. rust-tipped bracts and comprise the new I. lacerata In addition, plants from streambeds in the Roggeveld that have large, white flowers, are not included in current accounts of the genus, and also represent a novel taxon, I. rivulicola. Lastly, I. rapunculoides var. robusta G.J.Lewis, the range of which falls entirely within that of var. rapunculoides and is usually sympatric with it. has pink flowers of similar structure, but four or five leaves and deep-seated corms with a collar of coarse fibres around the stem base. We raise this plant to species rank as I. robusta

Three new species of Diascia (Scrophulariaceae) from the Western Cape, South Africa
Authors: Steiner K. E.
Published: July 2015

Three new annual species of Diascia Link Otto are described from the Western Cape Province of South Africa. D. collina is characterized by greyish magenta flowers with two divergent yellow sacs containing oil-secreting trichomes. It is restricted to granite outcrops in the vicinity of Saldanha Bay, from the West Coast National Park and Langebaan north to Vredenburg. D. pusilla is closely related to D. collina. but differs from that species in having smaller flowers with shorter, ± parallel sacs, and posticous filaments that lack a protuberance where they bend sharply backwards towards the upper lip. It occurs in grey to whitish sands usually near seasonally moist or wet areas. It has not been found more than 35 km from the coast and ranges from Modderrivier, south o f Darling, north to Lambert’s Bay. D. appendiculata is related to D. diffusa (Thunb.) Benth. and is characterized by having small, mainly reddish lilac to greyish magenta flowers, two shallow depressions in the corolla tube at the base of the upper lip, and posticous filaments with sterile appendages. It is known from only six localities in the general vicinity of Citrusdal and occurs in fynbos vegetation on lower mountain slopes or flats, in loose alluvial sands derived from Table Mountain Sandstone.
Aloe in Angola (Asphodelaceae: Alooideae)

Published: July 2015

Botanical exploration of Angola was virtually impossible during the almost three-decade-long civil war. With more areas becoming accessible, there is, however, a revived interest in the flora of this country. A total of 27 members of the genus Aloe L. have been recorded for Angola. It is not unlikely that new taxa will be discovered, and that the distribution ranges of others will be expanded now that botanical exploration in Angola has resumed. This manuscript provides a complete taxonomic treatment of the known Aloe taxa in Angola. It includes, amongst other information, identification keys, descriptions and distribution maps.

New species of Geissorhiza (Iridaceae: Crocoideae) from the southern African winter rainfall zone, range extensions, taxonomic changes, and notes on pollen morphology and floral ecology
Authors: Goldblatt P. , Manning J. C. , Nänni I.
Published: July 2015

Field work during the past 15 years has resulted in the discovery of 12 new species of the western southern African genus Geissorhiza Ker Gawl. and range extensions for several more. Following a survey of pollen morphology in the genus, we describe new pollen types in one section each of the two subgenera: five species of section  Ciliatae Goldblatt and two of  section Weihea Eckl. ex Baker have more complex apertures than the plesiomorphic single aperture with a 2-banded oper­culum found in other species. In addition, populations currently referred to the typical white (cream)-flowered  G. inflexa (D.Delaroche) Goldblatt with larger, pink, red or purple flowers, have a third pollen type and are recognized as  G. erosa (Salisb.) R.C.Foster. The new species are G. altimontana from the high Langeberg near Grootvadersbos; G. helmei from the Piketberg; G. lupidosa from the Du Toits Kloof Mtns; G. monticola from the Swartberg; G. platystigma from Darling, north of Cape Town; G. sufflava from the Piketberg; G. tricolor from Riversdale (all subgenus Weihea (Eckl. ex Baker) Goldblatt); and G. cantharophila from the Klein Roggeveld; G. demissa from the Kamiesberg. Gitberg and Cold Bokkeveld; G. exilis from the Waaihoek Mtns in the Worcester District;  G. reclinata from the Swartberg: and G. saxicola from the northern Cedarberg-Pakhuis Mountain complex (all subgenus Geissorhiza). We also report range extensions and provide morphological notes for several species, including  G. monanthos Eckl.. new collections o f w hich show that the inclusion of G. leuisiae R.C.Foster in that species was incorrect and we resurrect the species. The addition of 12 new species and recognition of G. erosa and G. lewisiae bring to 99 the number of species in the genus. New identification keys for Geissorhiza are provided that include all new species. We have also accumulated observations of floral ecology in the genus and integrate them with what is known about this aspect of the biology of Geissorhiza. Unusual strategies include deceptive pollination in G. tulhagh- ensis F.Bolus by tabanid flies and in two species, pollination using empid flies in combination w ith halictid bees
Taxonomy of the genus Keetia (Rubiaceae-subfam. Ixoroideae-tribe Vanguerieae) in southern Africa, with notes on bacterial symbiosis as well as the structure of colleters and the ‘stylar head’ complex
Authors: Tilney P. M. , Van Wyk A. E.
Published: July 2015

The genus Keetia E.Phillips has a single representative in the Flora of southern Africa region (FSA). namely K.  gueinzii (Sond.) Bridson. The genus and this species are discussed, the distribution mapped and traditional uses indicated. The structures of the calycine colleters, and the ‘stylar head' complex which is involved in secondary pollen presentation, are elucidated and compared w ith existing descriptions. Intercellular, non-nodulating, slime-producing bacteria are reported in leaves of a Keetia for the first time. Differences between the southern African representativ es o f Keetia, Psydrax Gaertn. Afrocanthium (Bridson) Lantz B.Bremer, and Canthium s. str.. which for many years were included in Canthium s.I., are given.

New synonyms and a new name in Asteraceae: Senecioneae from the southern African winter rainfall region
Authors: Manning J. C. , Goldblatt P.
Published: July 2015

A review of the genera Othonna and Senecio undertaken for the forthcoming Greater Cape plants 2: Namaqualand-southern Namib and western Karoo (Manning in prep.) led to a re-examination of the taxonomic status of several species. This was facilitated by the recent availability of high-resolution digital images on the Aluka website (www.aluka.org) of the Drege isotypes in the Paris Herbarium that formed the basis of many species described by De Candolle in his Prodromus systematis naturalis regni vegetabilis. These images made it possible to identify several names whose application had remained uncertain until now. Each case is briefly discussed, with citation of additional relevant herbarium specimens. The following species are reduced to synonomy: O. incisa Harv. is included in O. rosea Harv.; O. spektakelensis Compton and O. zeyheri Sond. ex Harv. are included in O. retrorsa DC.; S. maydae Merxm. is included in S. albopunctatus Bolus, which is now considered to include forms with radiate and discoid capitula; S. cakilefolius DC. is included in  O. arenarius Thunb.; S. pearsonii Hutch, is included in O. aspertdus DC.; S. parvifolius DC. is included in S. carroensis DC.; S. eriobasis DC. is included in S. erosus L.f.; and S. lobelioides DC. is included in S. flavus (Decne.) Sch.Bip. The name S. panduratus (Thunb.) Less, is identified as a synonym of S. erosus L.f. and plants that are currently know n under this name should be called S. robertiifolius DC. The confusion in the application o f the names O. perfoliata (L.f.) Jacq. and O. filicaulis Jacq. is examined. O. perfoliata is lecto- typified against a specimen in the Linnaean Herbarium (LINN)  w ith radiate capitula. The name O. filicaulis correctly applies to a radiate species and is treated as a synonym of O. perfoliata. The vegetatively similar taxon with disciform capitula that is currently known as O. filicaulis should be known as ()  undulosa (DC.) J.C.Manning  Goldblatt, comb. nov. The new name O. daucifolia J.C.Manning Goldblatt is provided to replace the later homonym O. abrotanifolia (Harv.) Druce.

How homogeneous is West Coast Renosterveld? Implications for con­servation
Authors: Newton I. P. , Knight R. S.
Published: July 2015

In this paper, we test two published assumptions about West Coast Renosterveld, a highly fragmented vegetation type in South Africa. The first is that it is a homogeneous vegetation type. The second is that small fragments are subsets (in terms of species) of the larger fragments. We used three sets of data. Species lists showed that more than 44 % of the species identified at 16 sites were unique to that site. Examining the dominant and rare species occurring at subsites within large fragments showed that, on average three-quarters, and never less than half, of the species were confined to one subsite. Analyses of rare and endangered plant species lists showed that the average distance separating patches of the same species was almost 30 km. Only 36.4 % of the rare or endangered species localities coincided with a major ( 25 ha) fragment. Our first conclusion was that many endemic species are constrained by micro- or meso-habitat demands that are not immediately obvious to the observer, and hence the vegetation should not be considered locally homogeneous. Our second conclusion was that the smaller fragments ( 25 ha) are of importance for the conservation of West Coast Renosterveld plant species.

The Cytology of Mycosphaerella pinodes*
Authors: Van Warmelo K. T.
Published: July 2015

The behaviour of nuclei during ascus and spore formation and maturation in  Mycosphaerella pinodes (Berk. Blox.) Stone was studied by means of the HCl-Giemsa technique. The mechanisms of dikaryotization could not be determined but typical croziers were formed. Nuclear fusion occurred in the young ascus and was followed by four conventional successive divisions. At pachytene the chromosomes could be counted and measured. The haploid chromosome number was found to be 15. Ascospore delimitation could be seen at metaphase IV so that each spore is homokaryotic. Two nuclear divisions occurred in the ascospores so that each cell became quadrinucleate.

Ancient art, rhetoric and the Lamb of God metaphor in John 1:29 and 1:36
Authors: Nortjé-Meyer Lilly
Published: July 2015

Biblical scholars have given diverse explanations for the Lamb of God metaphor in John 1:29 and 1:36. Most scholars are of the opinion that ‘amnos’ refers to the Passover lamb. This explanation is not obvious from the context of the Fourth Gospel. To understand the metaphor ‘lamb’ or ‘amnos’ of God, one should understand the transferable meaning of the figure or image. In this comparison, only the vehicle, namely the lamb, is given. What and who the lamb is stays open. It can be anything within the limits of the other story elements that have the same qualities as a lamb. To uncover the communicative dynamics of the metaphor, the exegete must have insight into the meaning and function of the original metaphor. Rhetoric provides a clue for the interpretation of the metaphor, namely that it is a Lamb of God. Within the pericope other rhetorical clues like antithesis and varietas are also provided. These clues are important but do not explain the image of the lamb. In this study, these problems will be considered via another medium, namely Hellenistic art and imagesand their penetration into Judaism and Christianity during the 1st century CE. Hellenistic and biblical images will be used to give an alternative interpretation of the metaphor of the Lamb of God.
Stochastic Collocation on Unstructured Multivariate Meshes
Authors: Narayan Akil , Zhou Tao
Published: July 2015

Collocation has become a standard tool for approximation of parameterized systems in the uncertainty quantification (UQ) community. Techniques for least-squares regularization, compressive sampling recovery, and interpolatory reconstruction are becoming standard tools used in a variety of applications. Selection of a collocation mesh is frequently a challenge, but methods that construct geometricallyunstructuredcollocation meshes have shown great potential due to attractive theoretical properties and direct, simple generation and implementation. We investigate properties of these meshes, presenting stability and accuracy results that can be used as guides for generating stochastic collocation grids in multiple dimensions.
GPU Accelerated Discontinuous Galerkin Methods for Shallow Water Equations
Authors: Gandham Rajesh , Medina David , Warburton Timothy
Published: July 2015

We discuss the development, verification, and performance of a GPU accelerated discontinuous Galerkin method for the solutions of two dimensional nonlinear shallow water equations. The shallow water equations are hyperbolic partial differential equations and are widely used in the simulation of tsunami wave propagations. Our algorithms are tailored to take advantage of the single instruction multiple data (SIMD) architecture of graphic processing units. The time integration is accelerated by local time stepping based on a multi-rate Adams-Bashforthscheme. A total variational bounded limiter is adopted for nonlinear stability of the numerical scheme. This limiter is coupled with a mass and momentum conserving positivity preserving limiter for the special treatment of a dry or partially wet element in the triangulation. Accuracy, robustness and performance are demonstrated with the aid of test cases. Furthermore, we developed a unified multi-threading model OCCA. The kernels expressed in OCCA model can be cross-compiled with multi-threading models OpenCL, CUDA, and OpenMP. We compare the performance of the OCCA kernels when cross-compiled with these models.
