Otholobium Spissum
''Otholobium spissum'' is a dense, tangled, much branched shrub of up to high that is assigned to the Pea family. It has dull green, clover-like leaves and white, pea-like flowers with a streaky, triangular, purple nectar guide. The species grows in renosterveld in the central mountains of the Western Cape province of South Africa. This species flowers in July and August. Description ''Otholobium spissum'' is a dense, tangled, much branched shrub of up to high. Its greyish-brown branches are set with many white lenticels and are initially covered with white appressed soft hair. Next to the base of each leaf are two persistent, straight, awl-shaped stipules of long, which is longer than the softly hairy leafstalk or petiole of long. Each leaf further consists of three distinctly glandular, hairless, dull green, inverted egg-shaped leaflets of long and wide, with a wedge-shaped base, a smooth margin and slightly indented at the tip, but with the main vein extending beyon ...

Plantae
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Renosterveld
Renosterveld is a term used for one of the major plant communities and vegetation types of the Cape Floristic Region (Cape Floral Kingdom) which is located in southwestern and southeastern South Africa, in southernmost Africa. It is an ecoregion of the Mediterranean forests, woodlands, and scrub biome. Etymology Renosterveld directly translated in the Afrikaans language means "rhinoceros-field", a possible reference to the high number of rhinoceroses seen by the Afrikaner settlers at the time. It may also derive its name from the renosterbos ("rhinoceros bush - ''Elytropappus rhinocerotis''), which is a common species of shrub found here. The dull grey colour of renosterbos is similar to the colour of a rhino's hide. Geology Renosterveld plants grow on rich soil, which makes them more nutritious than typical fynbos plants. Typically, renosterveld is largely confined to fine-grained soils - mainly clays and silts - which are derived from the shales of the Malmesbury and Bokkeve ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

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''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...

Harry Bolus
Harry Bolus (28 April 1834 – 25 May 1911) was a South African botanist, botanical artist, businessman and philanthropist. He advanced botany in South Africa by establishing bursaries, founding the Bolus Herbarium and bequeathing his library and a large part of his fortune to the South African College (now the University of Cape Town). Active in scientific circles, he was a Fellow of the Linnean Society, member and president of the South African Philosophical Society (later the Royal Society of South Africa), the SA Medal and Grant by the SA Association for the Advancement of Science and an honorary D.Sc. from the University of the Cape of Good Hope. Biography Bolus was born in Nottingham, England. He was educated at Castle Gate School, Nottingham. The headmaster George Herbert regularly corresponded with and received plant specimens from William Kensit of Grahamstown, South Africa. Kensit requested that the headmaster send him one of his pupils as an assistant; Harry Bolus dul ...

Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and 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 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 ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ...

Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ''pi ...

Androecium
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ 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 ''microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the 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 stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in '' Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ...
