Psoralea Pilifera
''Psoralea pilifera'', synonym ''Otholobium piliferum'', is a small, softly hairy shrublet of up to high that has been assigned to the Pea family, with branches horizontal at the base with rising tips. It regrows from the underground rootstock after fire destroys the vegetation. It has clover-like leaves on short stalks and white, pea-like flowers flushed with mauve that grow in triplets in the axils of the upper leaves of the new shoots. The species is only known from near Makhanda, Eastern Cape province of South Africa. Flowers have been seen in September and January. This is a very rare species about which little is known and which is likely threatened with extinction. Description ''Psoralea pilifera'' is a small shrub, with branches that are horizontal at the base and rise at the tips. It regrows from its rootstock after fire destroys the above ground vegetation. It has many slender, striped stems of up to long that are covered in soft hairs that are pressed against the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either accid ...

Fynbos
Fynbos (; , ) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. The area is predominantly coastal and mountainous, with a Mediterranean climate. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% (8,500 fynbos) species of the Cape floral kingdom, where nearly 6,000 of them are endemic. The area continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it. Origin of the term The word '' fynbos'' is often taken literally to mean ''fine bush'', as in Afrikaans '' bos'' means '' bush'', whereas in this instance ''bush'' refers to the type of vegetation. Typical fynbos foliage is ericoid rather than ''fine''. The term in its pre-Afrikaans, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Stirton
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (James (< Latin ''-us'', see Spanish/ Portuguese ''Carlos''). According to Julius Pokorny, the historical linguist and Indo-European studies, Indo-Europeanist, the root meaning of Charles is "old man", from Proto-Indo-European language, Indo-European *wikt:Appendix:Proto-Indo-E ...

Thomas Robertson Sim
Thomas Robertson Sim (25 June 1858 in Northfield, Aberdeen, Scotland – 23 July 1938 in Durban, Natal (province), Natal) was a botanist, bryologist, botanical artist and Conservator of Forests in Natal, best known for his monumental work ''The Forests and Forest Flora of the Colony of the Cape of Good Hope'' which appeared in 1907. He was the eldest of five children of John Sim (1824–1901), a noted Bryology, bryologist and Isabella Thomson Robertson (1823-). Education and career Attended Old Aberdeen grammar school until 1873 and in 1874 was given special tuition at Marischal College, University of Aberdeen. In that same year he served as apprentice gardener in the Royal Horticultural Society's gardens in Chiswick. In 1878 he was appointed to the Kew Gardens, Royal Botanic Gardens at Kew where he received a training in botany under Sir Joseph Dalton Hooker. In 1879 he worked for a year in the Harvard University botanic gardens in Cambridge, Massachusetts. Here he was infl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psoralea Bolusii
''Psoralea'' is a genus in the legume family (Fabaceae) with 111 species of shrubs, trees, and herbs native to southern and eastern Africa, ranging from Kenya to South Africa. In South Africa they are commonly referred to as fountainbush (English); fonteinbos, bloukeur, or penwortel (Afrikaans); and umHlonishwa (Zulu). Etymology The name ‘''Psoralea’'' is derived from the Greek term ‘''Psoraleos’'', which means “affected with itch or with leprosy”. Psoralen occurs naturally in the seeds of '' Psoralea corylifolia'', and is used in PUVA (psoralen + UVA) treatment, for several diseases including such as psoriasis. Species 111 species are accepted: * '' Psoralea abbottii'' C.H.Stirt. * '' Psoralea accrescens'' * '' Psoralea aculeata'' L. * '' Psoralea acuminata'' * '' Psoralea affinis'' Eckl. & Zeyh. * '' Psoralea alata'' (Thunb.)

Stigma (botany)
The stigma (: stigmas or stigmata) is the receptive tip of a Gynoecium#Carpels, carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the Style (botany), style and ovary (botany), ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germination, germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals (Pollination syndrome#Biotic, ...

Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the Style (botany), style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds th ...

Androecium
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains sporangium, microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''.
