Beiträge zur Kenntnis der Sippenstruktur der Gattung Glaucium Miller (Papaveraceae). Part I
Authors: Mory Birgit
Published: August 2010

Die vorliegende Arbeit enthält die Revision der 22 Arten umfassenden Gattung Glaucium Miller. Ihr Areal erstreckt sich in Eurasien und Nordafrika von den atlantischen Küsten Europas und den Kanarischen Inseln bis zum Mongolischen Altai, wobei die meisten Arten der Orientalisch‐Turanischen Florenregion angehören.

Die Untersuchungen beruhen vor allem auf dem Studium eines umfangreichen Herbarmaterials. Morphologie, Anatomie und Chorologie liefern die wichtigsten Merkmale zu Klärung der infragenerischen und infraspezifischen Verhältnisse. So heben sich im infragenerischen Bereich zwei Sippen ab, die im Range von Sektionen bewertet werden. Differenzierungsmerkmale sind die Öffnungsweisen der Früchte in Korrelation mit weiteren Merkmalen wie denen der Blatt‐ und Sproßmorphologie, des Samens und der Pollenkörner. Die 4 Arten der sect. Acropetala Mory sect. nov. mit der akropetalen Öffnungsweise der Früchte werden in 3 Series gegliedert. Differenzierungsmerkmal der Series ist vor allem die Fruchtknoten‐ bzw. Fruchtbehaarung. Es konnte eine Art aus dem nördlichen Iran, G. elbursium Mory sp. nov. mit der Unterart, G. elbursium subsp. ventii Mory subsp. nov. beschrieben werden. Von drei Arten wurden Unterarten abgegrenzt: G. refractocarpum Gilli subsp. erectocarpum Mory subsp. nov., G. calycinum Boiss. subsp. aserbaidshanicum Mory subsp. nov. und G. oxylobum Boiss. et Buhse subsp. rechingeri Mory subsp. nov.

Die phylogenetischen Beziehungen der Gattung werden in einem Stammbaum dargestellt. Die sect. Acropetala wird als primitiver gegenüber der sect. Glaucium angesehen. Besondere Berücksichtigung bei der Beurteilung der Merkmale fanden eine Reihe paralleler Entwicklungen vor allem von Merkmalen des generativen Bereichs wie des Andrözeums und der Früchte. Zum Schluß der Arbeit wird ein Bestimmungsschlüssel vorgelegt, der Arten, Unterarten und Varietäten enthält.

Authors: Passarge Harro
Published: August 2010

Nach Klärung des Begriffes Vikarismus werden Kriterien zur syntaxonomischen Bewertung syngeographischer Abwandlungen (Rasse, Vikariante Regionalassoziation), aufgezeigt und am Beispiel subkontinentaler Saumgesellschaften: Peucedanetum cervariae, Thalictretum mini, Vicietum tenuifoliae, Trifolietum alpestris, Vincetoxicetum, Peucedanetum oreoselini, Betonicetum officinalis, Agrimonietum eupatorii, Melampyretum nemorosi erörtert (s. Tab. 1–13). Ihre Homogenität wird anhand des „relativen Konstanten‐Anteils”︁ geprüft (s. Tab. 14). Alle beschriebenen Vegetationseinheiten lassen sich in vikariierenden Unterverbänden zusammengefaßt, dem Cynancho‐Geranion bzw. Trifolion medii zuordnen. (s. S. 80f.).
Observations on the cotyledonary and hypocotyledonary stomata and trichomes in some Caesalpiniaceae with a note on their taxonomic
Authors: Reddy P. K. R. , Shah G. L.
Published: August 2010

The structure and ontogeny of stomata on cotyledons and hypocotyls and the trichomes on hypocotyl are accounted for in eighteen species of Caesalpiniaceae. Trichomes are eglandular, bi‐ rarely tri‐celled, smooth walled or walls wavy with cuticular striations or tubercles. Anomocytic, haplocytic, paracytic, diacytic, transitional, tetracytic, tricytic and cyclocytic stomata occur in different combinations even on the same surface of the cotyledon. In all, there are fourteen combinations. Inspite of the diversity, the most frequent type is anomocytic in most of the species and paracytic in some species of Cassia and Delonix (abaxial) but rarely it is haplocytic or anisocytic. In hypocotyls it is anomocytic. Ontogenetically anomocytic, tetracytic and cyclocytic stomata are perigenous, whereas other types are mesogenous or mesoperigenous. There is an increase in the number of subsidiary cells by their division or the neighbouring perigenes assuming their shapes. About eight such types are described. A pair of stomata has a common subsidiary cell. Twelve types of guard cell and stomatal approximation abnormalities are described. A range in the number, size and shape of the nuclei in guard cell are recorded. Megastomata (giant stomata) are observed in Parkinsonia and Tamarindus. The taxonomic significance of the stomata is also discussed.

A taxonomical monograph of Anemia subgenus Anemiorrhiza (Filicinae)
Authors: Duek J. J.
Published: August 2010

The morphology of the specimens contained in the herbaria B, P, S and US were studied. The subgenus Anemiorrhiza comprise 12 taxa(2 infraspecific) 3 hybrids and have 12 synonyms. Descriptions, keys and distribution by countries are given. A set of characters is postulated as a pattern of variation (state variables) for the genus Anemia. And based on it a numerical classification under information theory is presented. A modified WAGNER'S tree is hypothesised to account for the branching secuence and the amount of divergence between the species of the subgenus Anemiorrhiza.

Das Zusammenvorkommen von Radula sphaerocarpoides sp. n. mit Frullania acutata CASPARY und Lejeunea latiloba CASPARY im selben Bernsteinstück belegt erstmals ein Bruchstück einer eozänen Mooszönose. R. sphaerocarpoides sp. n. ist der zweite paläontologische Nachweis der Radulaceae.
Taxonomy, Distribution and Ecology of the Canadian Labiatae
Authors: Gill L. S.
Published: August 2010

The author presents the distribution maps of all the known species of the Labiatae occurring in a wild state in Canada. Sixty eight species and nine hybrids of this family are recognized to occur in Canada. Generic and specific keys are given. The bioclimatic requirements for each taxon are discussed. The native species are grouped into four categories: (1) Species of widespread occurrence in Canada and there are eight such species. (2) Species mainly distributed in southeastern climatic region of Canada and these are 15 species in this category. (3) Prairie species. This includes 6 taxa. (4) Species restricted to Pacific climatic region and there are only three species. The introduced species are grouped into three categories: (1) Naturalized and widely distributed and this includes 11 species. (2) Naturalized and restricted in distribution, but established and persisting. There are 23 taxa in this group. (3) Species of sporadic occurrence which do not usually persist for a long time and this category includes 11 taxa. It is also concluded that 12 species do not occur in Canada as no specimen could be traced to support the record and these should be excluded from the Canadian Labiatae.

Taxonomic studies of the genus Ageratum L. in India
Authors: Sahu T. R.
Published: August 2010

Two species of the genus Ageratum L., viz., A. conyzoides and A. houstonianum are rather poorly distinguished morphologically. The former which has sparsely hairy involucre bracts and light blue heads is distributed throughout India. The latter is known to occur in Northern parts of the country and has densely hairy bracts and blue heads. Polygraph constructed on the basis of taximetric analyses of 16 quantitative characters, revealed significant similarities in most of the characters. They were also found similar in trichome types, the details of these have been discussed by the author (1979). On the basis of these studies it appears that two species which are not very clearly distinguishable, may better be merged together into one species and A. houstonianum may be treated as variety houstonianum of the species A. conyzoides.
Vegetation of inland desert wadies in Egypt. II. Wadi El‐Matuli and Wadi El‐Qarn
Authors: El‐Sharkawi H. M. , Fayed A. A. , Salama F. M.
Published: August 2010

Torrential rains (in January 1980) that had suddenly swept a limited area in the eastern desert facing Qena Province (Upper Egypt) resulted in enriching the vegetation of some extremely dry wadies at this location. Vegetation survey carried out shortly after this event (in April) revealed the prevailance of annuals which are hardly recognizable in such usually dry habitats and in considerable abundance. The normally scarce perennial vegetation has flourished too. The investigation reveals that the wadies studied are potential shelters of 3 community types, one of which seems to be a segetal part of an “Alliance” wide‐spread in other wadies of this desert. Distribution of such vegetation units seems to be controlled by relative aridity of the soil as well as by soil depth.
Zur Kenntnis der Fruchtmorphologie der Papaveraceae Juss. s. str. und der Hypecoaceae (Prantl et Kündig) Nak
Authors: Brückner Claudia
Published: August 2010

Basierend auf vergleichend‐morphologischen Untersuchungen an 20 Papaveraceae‐Gattungen wird eine Beschreibung der Fruchtmorphologie (incl. Anatomie) für jede Gattung gegeben. Bei 4 Gattungen konnte lediglich auf Angaben aus der Literatur zurückgegriffen werden. Für die 4 Triben sind bestimmte Kombinationen von Differenzierungsmerkmalen charakteristisch. Besondere Beachtung fanden dabei die Struktur der äußeren und inneren Perikarp‐Epidermis, die Chlorenchym‐Verteilung, der Verlauf der Milchröhren, die Gynoeceumsvaskulatur und die Dehiszenzform. Die homokarpellaten Platystemoneae (Unterfamilie Platystemonoideae) sind von den heterokarpellaten Papaveroideae klar abgegrenzt. Die Chelidonieae sind u. a. nach den Dehiszenzformen die plastischste Tribus, hier finden sich zahlreiche ursprüngliche Merkmalsausprägungen. Die sich explosiv akropetal öffnenden Kapseln der Eschscholzieae sind anatomisch relativ einheitlich. In den Papavereae treten nur unvollständig basipetal dehiszierende Früchte auf, die durch fehlende Valvendorsalnerven und im Phloëm verlaufende Milchröhren charakterisiert sind. Bestimmte Strukturen weisen auf nähere Bezichungen zwischen Einzelgattungen hin, jedoch rechtfertigt dies keine taxonomische Neugliederung der Familie. Die Hypecoaceae stehen den Chelidonieae (Glaucium, Dicranostigma) und den Eschscholzieae nahe. — Ein phylogenetisches Schema zeigt die karpomorphologischen Beziehungen in den Papaveraceae.

Trichome studies in Parthenium hysterophorus and their taxonomic importance
Authors: Sahu T. R.
Published: August 2010

In Parthenium hysterophorus L. four trichome types i.e. (1) cylindrical hair, (2) moniliform hair, (3) simple multiseriate hair and (4) shaggy hair, have been recognized mostly on the basis of their structural differences. In the past, these types have not been observed in any species of Parthenium studied so far. Out of these four, two types i.e. cylindrical and moniliform hairs are known to occur in the Compositae and remaining two i.e. simple multiseriate and shaggy hairs are the new forms for the family and have been observed for the first time in presently investigated species. Trichomes are an important taxonomic tool in distinguishing between genera and species. Trichomes of the different species of Parthenium as noticed from their structure are useful in distinguishing these species and even their corresponding organs.

Chemosystematics of some Indian members of the tribe Phaseoleae (Fabaceae)
Authors: Dutt C. B. S. , Daniel M. , Sabnis S. D.
Published: August 2010

Twentysix members belonging to the tribe Phaseolae (Fabaceae) have been analysed for their leaf flavanoids, phenolic acids, alkaloids and saponins. It is found, that all the subtribes within, possessed district assortment of chemical characters and therefore their elevation to tribes ist supported. Clitoria and Butea, being chemical dissimilar to other members of the Glycineae and Erythrineae, find a proper place in Euphaseoleae (Tribe Phaseoleae of Hutchinson) and Galactieae respectively. The varietel status of Teramnus labialis var. mollis ist upheld and the status of a separate species is recommended for Rhynchosia minima var. laxiflora Bak.

The significance of the three independent ‘Kew’ editions of JOHNSON'S Gardener's Dictionary
Authors: Mabberley D. J.
Published: August 2010

The various editions of JOHNSON'S Gardener's Dictionary (1846–1917) are discussed and the three ‘Kew’ editions (1882, 1894, 1917) examined in the context of contemporary horticultural and botanical publications, notably those issued by nurserymen and botanic gardens. Besides some 280 additions to Index kewensis and Index filicum, there are numerous changes in authorities of currently used species names, a change in Acalypha and restoration of Cyrtanthus × hybridus, while new combinations in Canistrum and Rhododendron and a new name in Maytenus are proposed.
Taxonomy of medicinal plants I. Epidermal morphology of the genus Khaya (Meliaceae) in West Africa
Authors: Olowokudejo J. D. , Nyananyo B. L.
Published: August 2010

Leaf epidermal morphology of four West African species of Khaya (Meliaceae) has been studied using both light and scanning electron microscopy. The cuticle may be striate, reticulate or verrucose. Epidermal cells are either isodiametric or irregular in shape. The anticlinical walls are of variable thickness and their positions are marked by raised ridges or shallow irregular grooves. Periclinal walls may be flat, concave or convex.

Anomocytic stomata which are either superficial or slightly sunken occur in all taxa. Stomatal size and index are variable among all species. A dichotomous key for identifying the species, even if they are in a fragmentary condition, is presented.
Studies on the cystoliths of Acanthaceae
Authors: Inamdar J. A. , Chaudhari G. S. , Rao T. V. Ramana
Published: August 2010

The occurrence, type of cystoliths, their size and frequency are worked out in 46 species belonging to the family Acanthaceae. Cystoliths are observed in all species, except in seven species belonging to tribes Thunbergieae, Nelsonieae, Acantheae and Justicieae. Cystoliths are classified into eleven types. They are mostly solitary, elongated, narrow or broad, pointed or blunt at one or both ends. However, double and rarely triple cystoliths are also observed. The size of the cystoliths varies even in the same species. The length/breadth ratio varies insignificantly for the species. The frequency of cystoliths in the Acanthaceae manifests conformity within a genus. However, the characteristics of the cystoliths may not be profitably used as a taxonomic tool.

Authors: Perrino P. , Maruca G. , Lester R. N. , Linsalata V. , Lattanzio V. , Hanelt P.
Published: August 2010

Chemotaxonomic investigations of leaf flavonoids by paper chromatography have shown that the cultigen Vicia faba is very distinct from the wild species V. hyaeniscyamus, V. johannis, V. serratifolia, V. narbonensis, V. galilaea and V. bithynica: the progenitor of V. faba remains unknown. No significant differences in chromatographic profiles were found between ten accessions of Vicia faba, which ranged from primitive land‐races to advanced cultivars, but there were highly significant differences between growth chamber and field grown plants.

Fruchtanatomische Studien an Dictamnus albus L., Zanthoxylum simulans Hance, Ptelea trifoliata L. und Ruta graveolens L. (Rutaceae)
Authors: Brückner Claudia
Published: August 2010

Die Frucht von Dictamnus albus besteht aus freien, an der Basis untereinander verwachsenen Karpellen, Zanthoxylum simulans hat chorikarpe Früchte, Ptelea trifoliata besitzt synkarpe Früchte, und bei Ruta graveolens werden die Früchte nach der Anthese vollständig synkarp, während die freien Griffeläste postgenital fusionieren. Die Perikarp‐Anatomie wird vergleichend analysiert und illustriert. Die histologischen Bedingungen für die Kombination aus ventrizider und loculizider Dehiszenz bei Dictamnus und Zanthoxylum sowie die loculizide Dehiszenz von Ruta werden dargestellt. Das Vaskulaturmuster in der Ventralregion weicht zum Teil etwas von dem für die Fruchtknoten zur Anthesezeit in der Literatur beschriebenen ab. Die karpologischen Merkmale werden diskutiert und ihre Aussagekraft für systematische Aussagen eingeschätzt. Zwischen Dictamnus und Ptelea gibt es eine größere Anzahl fruchtanatomischer Gemeinsamkeiten. Das unterstützt den in der Literatur gemachten Vorschlag, Ptelea in die Unterfamilie Rutoideae zu überführen. Für eine engere Verwandtschaft von Ruta und Dictamnus, wie sie sich im System von Engler (1931) widerspiegelt, können karpologisch keine Beweise erbracht werden.
Floral anatomy of some Melastomataceae
Authors: Satyavathi D. V. L. , Narayana L. L. , Devi D. Rama
Published: August 2010

The floral anatomy of five taxa of Melastomataceae, namely, Memecylon edule, M. guinensis, M. capitellatum, Rhexia marina and Tabouchina semidecandra has been studied. The regular, epigynous flowers are tetramerous in Memecylon edule, M. capitellatum, Rhexia marina and pentamerous in M. guinensis and Tabouchina semidecandra. The floral parts as well as their traces show varying degrees of adnation. The septate condition of the ovary in Rhexia marina and Tabouchina semidecandra and the presence of rudimentary septa in Memecylon edule, M. guinensis and M. capitellatum reveal that the central placentation in the family is derived from axile or anatomically parietal ancestry. The carpels are 3‐traced in Memecylon edule, M. guinensis and M. capitellatum and 5‐traced in the rest. The style is vascularized by the dorsal bundles in Memecylon species and by the common median laterals in Rhexia marina and Tabouchina semidecandra.
Features of foliar epidermis and stomata in eight species of Alternanthera (Amaranthaceae)
Authors: Mohan A. Ch. , Raju Vatsavaya S.
Published: August 2010

The features of mature foliar epidermis and stomata are described in eight species of Alternanthera. They showed diversity as regards the size of the epidermal cells and the nature of anticlinal walls; the stomatal size, frequency, index and basic type also varied. The epidermal cells are generally polygonal or irregular in outline while the anticlinal walls are usually sinuous, occasionally undulate or arched. The stomatal size varied from 20.3 × 13.6 μm (A. bettzichiana) to 37.4 × 18.8 μm (A. philoxeroides). Rather unusually, within the eight taxa examined, the genus showed as many as three basic stomatal types, namely, diacytic, paracytic and anisocytic.
Gradient analysis of canal vegetation in Nile delta region
Authors: Shaltout K. H. , El‐Sheikh M. A.
Published: August 2010

The present study aims at evaluating the behaviour of 15 common weeds, distributed along the net of canals and drains in the Middle Delta region, in relation to environmental gradients of some soil variables.

Some species have significant simple correlations (either positive or negative) with certain soil variables (salinity, CaCO3, nitrogen and organic matter). Some other species have monomodal behaviours along some soil gradients, while all the examined species have bimodal behaviours along, at least, one soil gradient. The possible reasons that could be lead to bimodality were discussed.

Authors: Perrino P. , Shagarodsky T. , Esquivel M. , Uranga H. , Hammer K.
Published: August 2010

The cultivated species of the genusVignain Cuba have been studied on the basis of living material collected during recent missions and herbarium material. The highest variability was found inVigna unguiculatasubsp.unguiculata.Probably this race has been early introduced by the Spaniards to Cuba. Later on several species were introduced by east Asiatic immigrants. Introgression and adaptation are considered as the main causes for building up a pronounced infraspecific variation inVigna unguiculata.A key for the cultivated species is provided.

The free amino acids of the leaves have been analysed in nine species of Tephrosia. The presence of fortythree amino acids in all, has been detected and of these, twenty‐eight are non‐protein ones. The exclusive presence of certain non‐protein amino acids in some species has been found to be taxonomically useful.
Primulales ‐ a reassessment of the taxonomy and phylogeny of the group With one Figure and one Table
Authors: Geetha K. , Umadevi I. , Daniel M.
Published: August 2010

A study on the foliar phytochemicals of the members of Primulaceae and Myrsinaceae revealed that the former family characteristically produces unique flavones and the latter the common flavonols. The uniqueness of the Primulaceae is brought out and a probable origin from the Violales is proposed. Myrsinaceae and Theophrastaceae are grouped in the Myrsinales which are derived from the Theales. Due to their probable relationships, the Plumbaginaceae also are included in the Myrsinales.

Authors: El‐Din A. Sharaf , El‐Kady H. F. , Sodany Y.
Published: August 2010

The present study aims at evaluating the behavior of 12 wild species, distributed at the saline and marshy habitats in the North Delta region, in relation to some soil variables. Some species have significant simple correlation with certain soil variables (salinity, CaCO3, nitrogen and organic matter). Some other species have bimodel behavior along some soil gradients, while all the examined species have monomodal behavior along, at least, one soil gradient.
Embryology of Balsaminaceae — I
Authors: Raghuveer M. , Narayana L. L.
Published: August 2010

The development of anther, ovule, male and female gametophytes has been studied in ten species of Impatiens. The floral parts develop acropetally. The anther wall development follows the ‘basic’ type. Sterile bands of sporogenous origin, divide the sporo‐genous tissue in small groups. The present study confirms the tetrasporangiate nature of the anthers in I. clavicornu refuting the statement of SHIMIZU et al. (1990), that they are trisporangiate. Cytokinesis takes place by furrowing. Ripe pollen is 2‐celled and the generative cell is elongated. The pollen grains are 3‐ to 5‐colpate and show onci.

The ovule in Impatiens is tenuinucellate, bitegmic, and anatropous with dorsal raphe. The integuments are free in I. grandis (I. hookeriana) and fused nearly to the top in the remaining species. The micropyle is formed by the inner integument alone. An endothe‐lium is differentiated. Both linear and T‐shaped megaspore tetrads have been observed. The embryosac development conforms to the Allium type in I. oliveri and Polygonum type in the remaining species. The antipodals are ephemeral. Polar nuclei fuse before fertilization. The embryosac elongates crushing the nuclear cells below and reaches the chalazal end. The mature embryosac borders upon the endothelium.
The genus Malabaila HOFFM. (Umbelliferae: Tordylieae): A carpological investigation and taxonomic implications
Authors: Pimenov M. G. , Ostroumova T. A.
Published: August 2010

Malabaila graveolens BIEB., a generotype of Malabaila, has been shown to be identical or very similar to the species of Pastinaca in all essential taxonomic characters including carpological. Thus the species and closely related, if the separate. M. vaginans are the members of Pastinaca. But it is impossible to include all other “Malabailas” into Pastinaca, because they differ from the latter in some significant features of fruit structure. These species form a separate genus, intermediate between Pastinaca (incl. Malabaila s. str.) and Zosima. Its correct name seems to be Leiotulus EHRENBERG. The detailed carpological descriptions and synonymy summaries for all Leiotulus species have been given, and new nomenclatural combinations have been proposed.

Authors: Sharma N. K. , Sharma K. C.
Published: August 2010

In Tephrosia purpurea the ovary is superior, unilocular and ovules are bitegmic and campylotropus. The seedcoat is derived from the outer integument alone. The mature seedcoat is differentiated into a layer of macrosclereids and osteosclereids underlain by 5–6 layers of parenchymatous cells. SEM studies of seed surface in T. purpurea show reticulate pattern and T. strigosa shows polygonal areas.

Bei Tephrosia purpurea ist der Fruchtknoten oberständig unilokular und die Samenanlagen sind bitegmisch und gekrümmt. Die Samenhülle ist ausschließlich vom äußeren Integument abzuleiten. Die reife Samenhülle gliedert sich in je eine Schicht von Makrosklereiden und Osteosklereiden, die von 5–6 Schichten von Parenchymzellen unterlagert werden. SEM‐Untersuchungen der Samenoberfläche erbrachten für T. purpurea ein retikulates Muster, für T. strigosa polygonale Bereiche.

Authors: El‐Ghani M. M. Abd
Published: August 2010

Weed plant communities of orchards in Siwa Oasis have been studied. Phytosoziological analysis was carried out based on 116 releves selected from the cultivated land where orchards habitat dominating the plant life. Three associations have been discussed, and defined mainly according to their floristic structure and composition as well as their environmental relationships. Two of them: Convolvulo (arvensis)‐Imperatetum cylindrici and Euphorbio‐Stellarietum medici were described as new syntaxa in the present study. Floristic analysis revealed the modest representation of pure Mediterranean taxa, while bi and pluriregional taxa constitute the main bulk of the flora of orchards in Siwa Oasis, denoting the severe human interference in this area.

Enumeratio Albucarum (Hyacinthaceae) Austro‐Africanarum adhuc cognitarum 2. Subgenus Falconera (SALISB.) BAKER emend. U.M‐D. 1987
Authors: Müller‐Doblies U.
Published: August 2010

An alphabetical list of species of Albuca subgenus Falconera (19 species including 13 new ones) is presented with notes on their distribution. For the six old species the diagnostic characters are provided with occasionally additional comments. For the new species diagnoses and an explanation of the epitheton are given. All 19 species are illustrated by at least one figure.

Like subgenus Albuca it has its main distribution in the Cape Province radiating to the east with one species into Natal and Transvaal and northwards into Namibia with four species, one of them only known from the type locality, and one occurring in Namibia and Angola. Thus the subgenus Falconera is strictly speaking not endemic to Southern Africa.

Within subgenus Falconera two sections are distinguished, sect. Falconera (14 spp.) with six fertile anthers and sect. Trianthera (five spp.) with only three fertile anthers.

Only two accepted species (A. fragrans JACQ. and A. viscosa L.f.) were already described in the eighteenth century, in each of the following centuries two accepted species were added (A. shawii BAKER and A. monophylla BAKER in the nineteenth century, and A. bifoliata DYER and A. crudenii ARCHIBALD, both from the Eastern Cape, in this century until 1956).
Comparative examination of the moving process in monocot and dicot seedlings using the example Lapeirousia laxa (Iridaceae) and Foeniculum vulgare (Apiaceae)
Authors: Pütz N. , Sukkau I.
Published: August 2010

Geophytes require a special depth in the soil, and therefore, seedlings of many plant species move downward very soon after germination. In this paper, a comparison is made using two examples, the monocotyledonous Lapeirousia laxa and the dicotyledonous Foeniculum vulgare. Using time lapse photography, functional differences become clear, characterised by typical seedling morphology.

During germination of Foeniculum vulgare, the hypocotyl elongates, which later has to be compensated by root and hypocotyl contraction in order to give the perennation buds a lower position for sprouting in the following year. In Lapeirousia laxa the primary internodes remain short, and form the perennation organ (a corm), with their perennation buds protected by soil from the outset. Downward movement of the corm occurs by the contractile roots which develop successively at the corm. At the end of the first vegetation period, the corms of Lapeirousia laxa are in a 60–100 mm deeper position. In contrast, Foeniculum vulgare develops a turnip as its perennation organ, which, through self‐contraction causes the perennation zone to become lower. At the end of movement, the perennation buds are approximately 15–25 mm below the soil surface, while the total movement of the buds is measured to be 30–40 mm.
