SummaryBergqvist, G., Bremer, B. & Bremer, K.: Chloroplast DNA variation and the tribal position of Eremothamnus (Asteraceae). – Taxon 44: 341‐350. 1995. – ISSN 0040‐0262.The genus Eremothamnus has been classified in several tribes, in recent times either in the Arctoteae or in a new tribe Eremothamneae; because of its isolated position within the family, it has also been left unclassified as to tribe. Chloroplast DNA restriction site data for Eremothamnus, suitable for comparison with similar data provided in the literature for other genera of the Asteraceae, and the rbcL gene sequence for Eremothamnus when compared with those of other Asteraceae, both indicate that Eremothamnus is related to the Arctoteae and may be classified in that tribe.

SummaryBaum, D. A. & Oginuma, K.: A review of chromosome numbers in Bombacaceae with new counts for Adansonia. – Taxon 43: 11‐20. 1994. – ISSN 0040‐0262.New chromosome counts are reported for all eight species of Adansonia. The six Malagasy species and the Australian species have 2n = 88, whereas the single African species, A. digitata, has 2n = 160. We review published counts for the family as a whole and conclude that there have been many inaccurate counts but that 2n = 86‐92 appears to be general. A. digitata, Rhodognaphalon brevicuspe and Eriotheca pubescens are inferred to be polyploids. The tribe Durioneae, with counts of 2n = 28 and 2n = 56, is distant from the remainder of the family, as also suggested by morphological, biogeographic and molecular data.
Four new genera of woody Apiaceae of Madagascar

SummaryVan Wyk, B.‐E., Tilney, P. M. & Winter, P. J. D.: Four new genera of woody Apiaceae of Madagascar. – Taxon 48: 737‐745. 1999. – ISSN 0040‐0262.Eight Malagasi species of Apiaceae were previously misplaced in the African genus Heteromorpha but have been recently excluded from it. They, with the E. African species of Pseudocarum, have remarkably unspecialised fruits and do not fit within Drude's classification system for the family, as they combine vittae characteristic of the Saniculoideae and Apioideae. They have oil ducts in the fruit ribs (intrajugal vittae) in addition to the normal ones between the ribs (vallecular vittae). The species (except one) have dentate‐serrate leaf segments, and some also have dentate involucral bracts, reminiscent of the Saniculoideae. These characteristics are interpreted as symplesiomorphies, and the group of species as a whole is undoubtedly paraphyletic. A new generic classification is proposed, and a key to the genera and species is provided. Four genera, Andriana, Cannaboides, Pseudocannaboides, and Tana, are described as new, to accommodate seven species and one additional variety: A. coursii, A. marojejyensis, A. tsaratananensis, C. andohahelensis, C. andohahelensis var. denudata, C. betsileensis, Pseudocannaboides andringitrensis, and T. bojeriana. Pseudocarum laxiflorum and P. laxiflorum var. alticola are additional new combinations.

We review the sectional nomenclature ofSuaedato clarify priorities of sectional and generic names and to determine or assign types for each of these. The nomenclatural history ofSuaedahas been complicated by past misapplication of the nameS. fruticosato the generic type,S. veraForssk. ex J.F. Gmel., and incorrect author attribution as“Suaeda fruticosa(L.) Forssk.”, as well as confusion with the species correctly calledS. fruticosaForssk. ex J.F. Gmel. The generic type,Suaeda vera, is also the type ofS. sect.ChenopodinaMoq. (S. sect.LachnostigmaIljin, nom. superfl.), which is correctly namedS. sect.Suaeda. Suaeda fruticosais placed inS. sect.SalsinaMoq.Suaedasect.Brezia(Moq.) Volk. is reinstated overS. sect.HeterospermaIljin, andS. sect.Schoberia(C.A. Mey.) Volk. is reinstated overS. sect.ConospermaIljin. Other currently accepted sectional epithets includeLimbogermenIljin,PhysophoraIljin,Schanginia(C.A. Mey.) Volk.,MacrosuaedaTsvelev, andImmersaTownsend. Types are designated forS. sect.LimbogermenIljin,S. sect.SalsinaMoq., andS. sect.Schoberia(C.A. Mey.) Volk. and for the generic nameSchoberiaC.A. Mey.Suaedasect.PlatystigmaIljin is placed in synonymy underS. sect.Suaeda. Delineations of sections largely follow Iljin [1936.Sovietsk. Bot. 1936(5): 39–49], whose treatment has been generally supported by recent data on the distribution of C3and C4photosynthesis and leaf anatomy in the genus. Sections are delineated by the morphology of the gynoecium and the seed, by leaf anatomy, as well as by inflorescence type. Descriptions and lists of representative species are given for the nine currently accepted sections.

The analyses showed that the present division into two species is inappropriate and does not cover the levels of variation within theC. alpinum‐C. arcticumcomplex. Two alternative models for a new and functional taxonomy of the complex are discussed: (1) that there is one widely defined species,C. alpinum,including several subspecies, (2) alternatively that arctic and non‐arctic populations of what currently is namedC. arcticumbelong to two different taxa, both distinct fromC. alpinum.Our studies indicate the presence of several evolutionary lineages, which are not adequately accounted for by the recognition of a widely circumscribedC. alpinum,and support a subdivision of currentC. arcticuminto two separate species,C. arcticumLange s.str. andC. nigrescens(H.C. Watson) Edmondston ex H.C. Watson. A revised taxonomic treatment is presented.
Informatics: new media and paths of data flow
Authors: Wilson Hugh D. 
Published: April 2006

SummaryWilson, H. D.: Informatics: new media and paths of data flow. – Taxon 50: 381–387. 2001. – ISSN 0040‐0262.The international community of systematic botany is in the process of entering a networked, digital environment that, after initial development over the past five years, will dominate all aspects of scientific activity in the future. Emerging new technologies are transforming the Internet into a global neural network that presents systematic botany, and science in general, with future prospects that include remarkable opportunity and significant challenge. The products of systematic botany, previously generated locally as static, hardcopy documents, can now be presented as collaborative enterprises from distributed centers as high‐content, dynamic data resources that are constantly updated and refined. In addition, these products can be made available to a global user community in multiple forms that can be targeted for different user groups. The emerging Internet standard of “usage equals value” could place the products of systematic botany in a position to draw public interest, usage, and—most importantly—support. However, opportunities inherent in the coming “digital transition” will not be realised if traditional, hardcopy‐based, perspectives on collaboration, peer review, publication and “ownership” are retained. Scientific communities that are able to recognise new potentials and respond by establishing appropriate interactive protocols will enhance and advance their discipline in this new environment. They will also work to insure, via interaction and content review by professionals, that information available to the public is of the highest scientific quality.
The present situation and prospects of plant taxonomy in China
Authors: Ma Jin Shuang , Liu Quan Ru 
Published: April 2006

SummaryMa, J. S. & Liu, Q. R.: The present situation and prospects of plant taxonomy in China. ‐Taxon 47: 67–74. 1998. ‐ ISSN 0040‐0262.Facing still unresolved taxonomic problems in many plant groups and overshadowed by recent economic and social changes, classical plant taxonomy in China is seriously threatened by the gradual loss of taxonomists and funding, not to mention the extinction of undescribed plant taxa resulting from environmental degradation at the approach of the 21st century. The status of floristic projects, taxonomic publications, and the staff and students of herbaria and botanical institutes is presented. The solution to problems limiting plant taxonomic research and floristics in China appears to be dependent primarily on supporting current co‐operative projects and raising additional research funds through Chinese and international collaborative efforts.

It consists of C. 10 genera of cormous plants principally from western N. America (British Columbia to northern Guatemala). These had been included in Alliaceae, as tribe Brodiaeeae (subfamily Allioideae), but recent molecular and anatomical studies indicate that the group merits familial status. Petronymphe is not a member of this group but rather belongs in Anthericaceae. Agapanthus is misplaced in Alliaceae and, despite its superior ovary, should be considered a member of Amaryllidaceae, as subfamily Agapanthoideae. Alliaceae, Amaryllidaceae, and Agapanthoideae are recircumscribed, and Tulbaghieae raised to subfamilial status.

SummarySmith, J. F., Brown, K. D., Carroll, C. L. & Denton, D. S.: Familial placement of Cyrtandromoea, Titanotrichum and Sanango, three problematic genera of the Lamiales. – Taxon 46: 65‐74. 1997. – ISSN 0040‐0262.Cladistic relationships among Gesneriaceae and related families are investigated using ndhF sequence data, to establish the affinity of three genera whose familial placement was uncertain on the basis of morphological evidence alone. A first analysis, including 18 outgroup species from the Buddlejaceae, Scrophulariaceae, Bignoniaceae, and Acanthaceae resulted in eleven most‐parsimonious trees of 5740 steps each. Recent classifications had placed Cyrtandromoea in Scrophulariaceae or Gesneriaceae, Titanotrichum as a monogeneric tribe in Gesneriaceae, and Sanango in either Scrophulariaceae, Gesneriaceae, Loganiaceae, or Buddlejaceae, Sequence data from the chloroplast ndhF gene indicate that they are Gesneriaceae: Cyrtandromoea belongs to the Klugieae, the monogeneric Titanotricheae are perhaps sister to the remainder of the Cyrtandroideae, and Sanango is placed in the Gesnerieae as was predicted by recent morphological and chemical analyses.
Setchellanthaceae (Capparales), a new family for a relictual, glucosinolate‐producing endemic of the Mexican deserts
Authors: Iltis Hugh H. 
Published: April 2006

SummaryIltis, H. H.: Setchellanthaceae (Capparales), a new family for a relictual, glucosinolate‐producing endemic of the Mexican deserts. – Taxon 48: 257‐275. 1999. – ISSN 0040‐0262.Setchellanthus caeruleus Brandegee is a rare microphyllous shrub, densely pubescent with T‐shaped Malpighian hairs, with many stamens, 5‐7 free blue to lilac petals, an elongate, 3‐carpellate, deeply trisulcate ovary with axile placentation and proto‐parietal vasculature, and a straight embryo essentially lacking endosperm. It is known only from two widely disjunct areas in the Chihuahuan and Tehuacán deserts of northern and south‐central Mexico. The genus was named for phycologist W. A. Setchell (1864‐1963; a biographical note is included). Its taxonomy, morphology, and geography are outlined, and the results of four associated papers on flower and seed anatomy, vegetative anatomy, pollen structure, and nucleotide sequence of the rbcL gene are discussed. The species is so highly distinct in its relatively primitive morphology and chemistry that it is here placed into its own, newly established monotypic family near the Caricaceae and Moringaceae and basal to the core group of glucosinolate (mustard oil) producing families (but less basal than, e.g., Bretschneideraceae, Akaniaceae, and Tropaeolaceae). The new evidence supports Dahlgren's reclassification of an expanded order Capparales.

SummaryDorr, L. J.: Botanical libraries and herbaria in North America. 4. The Samuel Botsford Buckley – Rebecca Mann Dean mystery. – Taxon 46: 661‐687. 1997. – ISSN 0040‐0262.Samuel Botsford Buckley (1809‐1884) amassed a herbarium of approximately 6000 specimens through his own labours and through exchange with other botanists, mostly American but also European. This herbarium was acquired by Rebecca Mann Dean (1821‐1890), a professor of natural history and other subjects at Antioch College, Yellow Springs, Ohio, and wife of a bookstore owner who had a brief row with Buckley in the 1850s. Before her death, she sold Buckley's herbarium to Washington University, St Louis, Missouri. Within a few years of the sale, the herbarium was combined with that of the Missouri Botanical Garden. Neither the botanical activities of Buckley, which are fairly well understood, nor the nature of the transaction conveying the herbarium from Buckley to Dean, which is still problematic, could have been sketched without information contained in correspondence saved by botanical libraries and other scholarly institutions. The importance of keeping botanical libraries and archives in close proximity to herbaria is reaffirmed by this case study.

Unexpectedly, the analysis indicates strong support for placing Gundelia with tribe Lactuceae, rather than with tribe Arctoteae. Gundelia's morphology is discussed in light of this new grouping. Another clade, although weakly supported, is formed by representatives of Arctoteae, including the two South African genera Eremothamnus and Hoplophyllum. The latter two form a sister group with 100 % support.

This change, however, would so much disrupt the established nomenclature of the group that it is advisable to conserve the name P. mugo with a type that agrees with current usage.
