Gasteria Pillansii
''Gasteria pillansii'' (Namaqua gasteria) is succulent plant native to the arid winter-rainfall regions in the far west of South Africa and Namibia. Description This species of ''Gasteria'' has its strap-shaped leaves in two opposite rows (distichous), and is very variable in its appearance, and especially in its size. Its flowers are 25–45 mm long, with only slightly swollen bases for up to one-third of the length. In its vegetative appearance, it looks very similar to its two closest relatives, ''Gasteria disticha'' and '' Gasteria brachyphylla'' to the south, which are also distichous. However the flowers are different, with ''G. disticha'' having smaller flowers of just 12–20 mm which have flower bases that are inflated or swollen for roughly two-thirds of the flower length. It is proliferous, offsetting from underground stolons, and can form large clumps. It has pink flowers which appear in mid-summer around December. The seeds develop in time to be dis ...

Gasteria
''Gasteria'' is a genus of succulent plants, native to South Africa (and the far south-west corner of Namibia). Naming The genus is named for its stomach-shaped flowers (''"gaster"'' is Latin for "stomach") that result from the swollen base on the corolla. Common names include ''ox-tongue'', ''cow-tongue'', ''lawyer's tongue'' and, occasionally, ''mother-in-law's tongue''. Description Gasterias are recognisable from their thick, hard, succulent "tongue-shaped" leaves. These are either in two opposite ranks (distichous), or in various distinctive spiral arrangements. Their inflorescence is also unique, with their curved, stomach-shaped flowers, which hang from inclined racemes. Distribution The species of this genus are mostly native to the Eastern Cape Province, South Africa, where the bulk of the species occur – especially in the small area between Makhanda and Uniondale which enjoys rainfall throughout the year. However distribution of several species extends widely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Louisa Bolus
Harriet Margaret Louisa Bolus ''Married and maiden names, née'' Kensit (31 July 1877, Burgersdorp – 5 April 1970, Cape Town) was a South African Botany, botanist and taxonomist, and the longtime curator of the Bolus Herbarium, from 1903. Bolus also has the legacy of authoring more land plant species than any other female scientist, in total naming 1,494 species. Early life and education Bolus was born in Burgersdorp, Cape Province, South Africa, on 31 July 1877. She was the daughter of William Kensit and Jane Stuart Kensit. Her parents were both British-born. Her grandfather William Kensit was a serious amateur botanist and specimen collector in South Africa. She attended Collegiate Girls' High School in Port Elizabeth, earned a teaching credential in 1899, and was awarded a BA degree in literature and philosophy by the University of the Cape of Good Hope in 1902. Career She worked as an assistant to her great-aunt Sophia's husband Harry Bolus in his herbarium while she was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America).

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
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 ...

Distichous
In botany, phyllotaxis () or phyllotaxy is the arrangement of leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. Leaf arrangement The basic arrangements of leaves on a stem are opposite and alternate (also known as spiral). Leaves may also be whorled if several leaves arise, or appear to arise, from the same level (at the same node) on a stem. With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same node), on opposite sides of the stem. An opposite leaf pair can be thought of as a whorl of two leaves. With an alternate (spiral) pattern, each leaf arises at a different point (node) on the stem. Distichous phyllotaxis, also called "two-ranked leaf arrangement" is a special case of either opposite or alternate leaf arrangement where the leaves on a stem are arranged in two vertical columns on opposite sides of the stem. Examples include various bulbous plants such as ''Boophone''. It also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasteria Disticha
''Gasteria disticha'' is succulent plant native to the Western Cape, South Africa. Description This species of ''Gasteria'' has its strap-shaped leaves in two opposite rows (distichous), from whence its Latin species name comes. In its vegetative appearance, it looks very similar to the closely related species '' Gasteria pillansii'' to the north, and '' Gasteria brachyphylla'' to the south-east, both of which are also distichous. However the flowers are different, with ''G. disticha'' having tiny flowers of just 12–20 mm which have flower bases that are inflated or swollen for roughly two-thirds of the flower length. ''G. disticha'' often has leaves that undulate slightly, with wavy margins and a rough, mat surface. It is proliferous, with pink flowers and appears between September and December. Distribution It occurs in the Robertson Karoo vegetation of the Breede River Valley in the Western Cape, South Africa. It also extends marginally into the verges of ...

Gasteria Brachyphylla
''Gasteria brachyphylla'' ("Klein Karoo gasteria") is succulent plant native to the Western Cape, South Africa. Description This species of ''Gasteria'' has its strap-shaped leaves in two opposite rows (distichous). Its flowers are 12–22 mm long. It very closely resembles its two relatives, ''Gasteria pillansii'' and ''Gasteria disticha'' to the north, both of which are also distichous. However ''G. brachyphylla'' can be distinguished by its very shiny, smooth leaves (its two relatives' leaves are rough with tiny tubercles). ''"Brachyphylla"'' means "wide/short leaves", and this species's leaves are shorter than its relatives'. It is proliferous, and has pink flowers which appear around September.
