Protea Vogtsiae
''Protea vogtsiae'', also known as the Kouga sugarbush, is a small flowering shrub of the genus '' Protea'' within the family Proteaceae, which is only found growing in the wild in the southern Cape Region of South Africa. It was named after Marie Vogts. In the Afrikaans language it has been given the vernacular name of ''Marie-se-roossuikerbos''. Taxonomy ''Protea vogtsiae'' was first collected flowering in August 1972 at 1,067 metres elevation on the lower southern slopes of the Saptoukop mountain in the Kouga range near the town of Willowmore by the South African botanist John Patrick Rourke. Rourke subsequently described it as a species new to science in an article in the Journal of South African Botany published in 1974. An isotype of Rourke's original collection (#1396) is housed in the herbarium at the Kew Botanical Gardens. Classification ''P. vogtsiae'' was classified in section ''Crinitae'' by Tony Rebelo in 1995, what he calls the "eastern ground sugarbushes" ...

John Patrick Rourke
John Patrick Rourke FMLS (born 26 March 1942, in Cape Town) is a South African botanist, who worked at the Kirstenbosch National Botanical Garden and became curator of the Compton Herbarium. He is a specialist in the flora of the Cape Floristic Region, in particular the family Proteaceae. Career Rourke studied at the University of Cape Town from 1960 to 1970, where he obtained his B.Sc., M.Sc. and Ph.D. He started working at Kirstenbosch from 1966, and succeeded Winsome Fanny Barker as curator of the Compton Herbarium in 1972. He published several revisions of Proteacean genera including ''Leucadendron'', ''Leucospermum'', ''Mimetes'', ''Vexatorella'', '' Sorocephalus'' and '' Spatalla''. During his career he collected approximately 2000 specimens of flora from the southwestern and southern Cape, Namaqualand and eastern Transvaal. In 1997 he was made foreign member of the Linnean Society of London. In 2003 Rourke was awarded the "Gold medal for Lifetime Preservation of the ...

Isotype (biology)
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Involucral Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flower Head
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Glaucous
''Glaucous'' (, ) is used to describe the pale grey or bluish-green appearance of the surfaces of some plants, as well as in the names of birds, such as the glaucous gull (''Larus hyperboreus''), glaucous-winged gull (''Larus glaucescens''), glaucous macaw (''Anodorhynchus glaucus''), and glaucous tanager (''Thraupis glaucocolpa''). The term ''glaucous'' is also used botanically as an adjective to mean "covered with a greyish, bluish, or whitish waxy coating or bloom that is easily rubbed off" (e.g. glaucous leaves). The first recorded use of ''glaucous'' as a color name in English was in the year 1671. Examples The epicuticular wax coating on mature plum fruit gives them a glaucous appearance. Another familiar example is found in the common grape genus (''Vitis vinifera''). Some cacti have a glaucous coating on their stem(s). Glaucous coatings are hydrophobic so as to prevent wetting by rain. Their waxy character serves to hinder climbing of leaves, stem or fruit by insec ...

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plants Of Africa
''Flowering Plants of Africa'' is a series of illustrated botanical magazines akin to ''Curtis's Botanical Magazine'', initiated as ''Flowering Plants of South Africa'' by I. B. Pole-Evans in 1920. It is now published by the South African National Biodiversity Institute in Pretoria. The magazine depicts and describes flowering plants from Africa and its neighbouring islands. The issues are printed in soft cover measuring 250 x 190 mm. The first volumes were printed in England by L. Reeve & Co. These first illustrations were done in black and white by lithography, zinc plates later replacing the stone. A copy of the original water colour guided teams of hand-colour artists who applied paint where needed. Hand-colouring was a family craft carried on from generation to generation. Single colour printing was occasionally done to help speed the process, especially when skilled hand-colour artists were in short supply, as happened in World War II.

Protea Montana
''Protea montana'' also known as the Swartberg sugarbush, is a flowering plant of the genus '' Protea'' within the family Proteaceae, which is endemic to the southwestern Cape Region of South Africa. In Afrikaans it is known as ''swartbergsuikerbos''. Taxonomy ''Protea montana'' was first scientifically collected at elevation by the German plant collector and horticulturalist Johann Franz Drège in August 1829,The date 1840 is written on the herbarium specimen sheet at Kew, but this is doubtlessly not the collection date, as Drège had long returned to Europe by that time. Note Kew has indexed the same sheet three times. when he was exploring the eastern flanks of the Groot Swartberg Mountains with Karl Zeyher in the area of the farm of Vrolykheid. When he returned to Europe from Africa, he detailed his botanical adventures in his 1843 work ''Zwei pflanzengeographische Documente'', which detailed where he collected what each month in a brief diary-like format.
