Aloe Reynoldsii
'' Aloe reynoldsii '' is a species of plant in the Asphodelaceae family. Description ''Aloe reynoldsii'' is a succulent without a stem or with very short stems, with leaves gathered in a rosette. The leaves are bluish-green, elongated, fleshy, with a waxy texture, longitudinal lines and with numerous pale green spots and tiny whitish teeth on the margins. The inflorescences show numerous yellow tubular flowers, slightly swollen at the base. The flowering period occurs during September. ''Aloe reynoldsii'' is often confused with its close relative, ''Aloe striata'' (the coral aloe), and they do look very similar. However ''Aloe reynoldsii'' has waxy, toothed leaf margins and yellow flowers, while the coral aloe has smooth leaf margins and red flowers. Distribution and habitat This species is endemic to South Africa. Here it is found naturally in the far east of the Eastern Cape Province, where it occurs on cliffs near the mouth of the Bashee River, in areas with a high humidity ...

Cythna Letty
Cythna Lindenberg Letty (1 January 1895, in Standerton – 3 May 1985, in Pretoria), was a South African botanical artist and is regarded as a doyenne of South African botanical art by virtue of the quality and quantity of her meticulously executed paintings and pencil sketches, produced over a period of 40 years with the National Herbarium in Pretoria. Cythna Letty is best remembered for her book ''Wild Flowers of the Transvaal'' which was published in 1962. When decimal currency was introduced in South Africa, she was asked to design the floral motifs for the 10, 20 and 50 cent coins. Besides painting she was an accomplished poet and published ''Children of the Hours'' when she was in her eighties. Cythna was the eldest child of her mother Josina Christina Lindenberg's second marriage and was named after the heroine in Percy Shelley's poem "The Revolt of Islam". The Lettys had five children and for many years the six children from Josina's first marriage were part of an exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are predominantly photosynthetic eukaryotes of the 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 Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and 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 color. Some plants are parasitic or mycotrophic and have lost the ...

Asphodelaceae
Asphodelaceae is a family of flowering plants in the order Asparagales. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species. The type genus is ''Asphodelus''. The family has a wide but scattered distribution throughout the tropics and temperate zones. Many of the species are cultivated as ornamentals. A few are grown commercially for cut flowers. Two species of '' Aloe'' are grown for their leaf sap, which has medicinal and cosmetic uses. ''Xanthorrhoea'' is endemic to Australia. Description Members of the Asphodelaceae are diverse, with few characters uniting the three subfamilies currently recognized. The presence of anthraquinones is one common character. The flowers (the inflorescence) are typically borne on a leafless stalk ( scape) which arises from a basal rosette of leaves. The individual flowers have jointed stalks ( ...

Succulent
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as '' Glottiphyllum semicyllindricum'' and '' Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to s ...

Plant Stem
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The stems ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern '' Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. Ano ...

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 ...

Aloe Striata
''Aloe striata'', with the common name coral aloe, is a small, stemless South African Aloe species. Distribution This species occurs quite widely over the southern parts of the Cape Floristic Region, in the Eastern Cape Province and Western Cape Province of South Africa. It is found on rocky slopes in coastal and karoo areas. Description The coral aloe's specific epithet, ''striata'', means "stripes", and refers to the long lines (sometimes very faint) on its blue-green leaves. The leaves of this Aloe are not toothed, but have a smooth pink margin. Due to the similarity of their species names, ''Aloe striata'' is sometimes confused in literature with ''Aloiampelos striatula'' (syn. ''Aloe striatula'', hardy aloe) — a very different plant, found in the highlands of the Eastern Cape. Taxonomy The coral aloe forms part of the ''Paniculatae'' series of very closely related ''Aloe'' species, together with '' Aloe reynoldsii''. This species is often confused with its close rela ...

Eastern Cape
The Eastern Cape is one of the provinces of South Africa. Its capital is Bhisho, but its two largest cities are East London and Gqeberha. The second largest province in the country (at 168,966 km2) after Northern Cape, it was formed in 1994 out of the Xhosa homelands or bantustans of Transkei and Ciskei, together with the eastern portion of the Cape Province. The central and eastern part of the province is the traditional home of the indigenous Xhosa people. In 1820 this area which was known as the Xhosa Kingdom began to be settled by Europeans who originally came from England and some from Scotland and Ireland. Since South Africa's early years, many Xhosas believed in Africanism and figures such as Walter Rubusana believed that the rights of Xhosa people and Africans in general, could not be protected unless Africans mobilized and worked together. As a result, the Eastern Cape is home to many anti-apartheid leaders such as Robert Sobukwe, Oliver Tambo, Nelson Mandel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asphodeloideae
Asphodeloideae is a subfamily of the monocot family Asphodelaceae in the order Asparagales. It has previously been treated as a separate family, Asphodelaceae ''sensu stricto''. The family Asphodelaceae has now been proposed to be a nomen conservandum, and the proposal has been recommended for ratification in 2017. In that case, Asphodelaceae will have priority over Xanthorrhoeaceae. This is reflected in the APG IV family lists. The subfamily name is derived from the generic name of the type genus, ''Asphodelus''. Members of group are native to Africa, central and western Europe, the Mediterranean basin, Central Asia and Australia, with one genus ('' Bulbinella'') having some of its species in New Zealand. The greatest diversity occurs in South Africa. The genera ''Aloe'', ''Asphodelus'', and ''Kniphofia'' are perhaps best known from their use in horticulture as ornamental plants.
