Isoetes Stellenbossiensis
''Isoetes stellenbossiensis'', the Stellenosch quillwort or Cape Flats quillwort, is a species of plant from South Africa. Description This tufted geophyte has three-pointed scales. There are between five and thirty three spore bearing leaves, each of which grows up to long.e-Flora of South Africa. v1.36. 2022. South African National Biodiversity Institute. http://ipt.sanbi.org.za/iptsanbi/resource?r=flora_descriptions&v=1.36 This is the smallest ''Isoetes'' species in the region. The leaves have three well-developed groups of supporting tissue inside, giving them a firm texture. The air canals are poorly developed, with the adaxial canal ending before the end of the leaf. Each leaf has a small and delicate elongated appendage at its base. It starts of triangular, but often decays somewhat over time. The sporangia vary in size and do not have a membranous covering. They are usually bordered by a narrow rim, with some of the cells being noticeably thicker and a yellowish-br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Cape
The Western Cape is a province of South Africa, situated on the south-western coast of the country. It is the fourth largest of the nine provinces with an area of , and the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George. Geography The Western Cape Province is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about northwards along the Atlantic coast and about eastwards along the South African south coast ( Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by the Eastern Cape. The total land area of the province is , about 10.6% of the country's total. It is roughly the size of England or th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storage Organ
A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores. Plants that have an underground storage organ are called geophytes in the Raunkiær plant life-form classification system.; reprinted (1977) in ''History of ecology'' series, New York: Arno Press, Storage organs often, but not always, act as perennating organs which enable plants to survive adverse conditions (such as cold, excessive heat, lack of light or drought). Relationship to perennating organ Storage organs may act as perennating organs ('perennating' as in perennial, meaning "through the year", used in the sense of continuing beyond the year and in due course lasting for multiple years). These are used by plants to survive adverse periods in the plant's life-cycle (e.g. caused by cold, excessive heat, lack of light or drought). During these ...

Plants Described In 1929
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 abi ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crassula Dejecta
''Crassula'' is a genus of succulent plants containing about 200 accepted species, including the popular jade plant (''Crassula ovata''). They are members of the stonecrop family (Crassulaceae) and are native to many parts of the globe, but cultivated varieties originate almost exclusively from species from the Eastern Cape of South Africa. Crassulas are usually propagated by stem or leaf cuttings. Most cultivated forms will tolerate some small degree of frost, but extremes of cold or heat will cause them to lose foliage and die. Taxonomy ''Crassula'' was first formally described by Carl Linnaeus in 1753 with 10 species. Etymology The name crassula comes from the Latin adjective ''crassus'', meaning thick, referring to the thickening of the succulent leaves. List of selected species *''Crassula alata'' *'' Crassula alba'' *'' Crassula alpestris'' (Sand-Coated Crassula) *''Crassula alstonii'' *''Crassula aquatica'' (common pigmyweed, water pygmyweed) *''Crassula arbores ...

Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus '' Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks.

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as forage, feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of bi ...
