Haemanthinae
Haemanthinae is a small subtribe of Haemantheae, and therefore within the African clades of Amaryllidoideae. It consists of two genera, ''Haemanthus'', and ''Scadoxus''. Description The genera of Haemanthinae share brush-like inflorescences, in which the bracts frequently form part of the pollinator attraction system. Not all ''Scadoxus'' form bulbs, while all species of ''Haemanthus'' do. Taxonomy For the early taxonomic history of these two genera, see Meerow and Clayton (2004). Pax (1888) treated the Amaryllidaceae as four subfamilies, with two tribes in subfamily Amarylloideae, which consisted of two tribes, Amaryllideae and Narcisseae. The former contained six subtribes, placing ''Haemanthus'' together with ''Clivia'' in subtribe Haemanthinae. Hutchinson (1934) subsequently elevated this to tribe Haemantheae. Later, Traub placed ''Haemanthus'' with ''Choananthus'' (subsequently submerged in ''Scadoxus'') in tribe Haemantheae in his 1963 monograph on the Amaryllidacea ...

Haemantheae
Haemantheae are a tribe of subfamily Amaryllidoideae (family Amaryllidaceae). They are herbaceous monocot perennial flowering plants with a predominantly African distribution. Three subtribes are proposed and six genera including the type genus, ''Haemanthus'', are included. They are characterised by the presence of baccate (berry) fruit. Taxonomy Phylogeny The placement of Haemantheae within subfamily Amaryllidoideae is shown in the following cladogram: Subdivision There are three subtribes, with six genera * Cliviinae D.Müll.-Doblies & U.Müll.-Doblies * Haemanthinae Pax * Gethyllidinae Meerow The subtribes are related as follows: Cliviinae: Two genera - ''Clivia'', '' Cryptostephanus'' Haemanthinae: Type - two genera, ''Haemanthus'', '' Scadoxus'' Gethyllidinae: Two genera - ''Apodolirion'', ''Gethyllis ''Gethyllis'' (probably from Greek ''"gethyon"'', bulb), commonly called Kukumakranka, Koekemakranka, or Kroekemakrank, is a genus of bulbous plant ...

Amaryllidoideae
Amaryllidoideae (Amaryllidaceae ''s.s.'', amaryllids) is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG III, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae (the old family Amaryllidaceae), and the others are Allioideae (the old family Alliaceae) and Agapanthoideae (the old family Agapanthaceae). The subfamily consists of about seventy genera, with over eight hundred species, and a worldwide distribution. Description The Amaryllidoideae are herbaceous, perennial flowering plants, usually with bulbs (some are rhizomatous). Their fleshy leaves are arranged in two vertical columns, and their flowers are large. Most of them are bulbous geophytes and many have a long history of cultivation as ornamental plants. They are distinguished from the other two Amaryllidaceae subfamilies (Agapanthoideae and Allioideae) by their unique alkaloida ...

Gethyllidinae
Gethyllidinae is a small subtribe within the amaryllis family. It is within tribe Haemantheae, and therefore within the African clades of Amaryllidoideae. It contains two genera, ''Gethyllis'' and ''Apodolirion'', both are endemic to southern Africa. Description ''Gethyllis'' and ''Apodolirion'' are two unifloral genera with fused spathe bracts that retain the ovary inside the bulbs until the fruit matures. In both the scape remains inside the bulbs. The fruit is large, fleshy, and aromatic with many seeds, and distinct from the rest of Haemantheae which have berry fruits with only a few seeds. These seeds are also small and hard, while the rest of Haemantheae have seeds that are larger, fleshy and water rich. The genera are also distinguished from each other by their stigmata. In ''Gethyllis'' this is capitate, while in ''Apodolirion'' it is trifid. Also, ''Apodolirion'' has six stamina while ''Gethyllis'' has many more, with some species having 18 or more.

Cliviinae
Cliviinae is a small subtribe of Haemantheae, and therefore within the African clades of Amaryllidoideae. It consists of two genera, ''Clivia'', and ''Cryptostephanus''. Description Bulbless rhizomatous perennial plants. ''Clivia'' has showy orange or yellow flowers, while ''Cryptostephanus'' has smaller flowers with a paraperigone that had them erroneously classified with Narcissus in the past. it is also the only Haemantheae genus with a phytomelanous seed testa. Taxonomy For the early taxonomic history of these two genera, see Meerow and Clayton (2004). ( Traub described this grouping as tribe Clivieae in his 1963 monograph on the Amaryllidaceae, based on the type genus ''Clivia''. . Subsequently, the Müller-Doblies' reduced it to a subtribe and placed it within the Haemantheae. Later molecular phylogenetic research has confirmed this placement, with Cliviinae being one of three subtribes of Haemantheae. Phylogeny The Cliviinae are placed within the Haemantheae as ...

Haemanthus Coccineus
''Haemanthus coccineus'', the blood flower, blood lily or paintbrush lily, is a species of flowering plant in the amaryllis family Amaryllidaceae, native to Southern Africa. Growing to tall and wide, it is a bulbous perennial with short brown stems surmounted by red flowers, the flowers appearing in spring and summer, before the strap-shaped leaves. The generic name ''Haemanthus'' is derived from the Greek words ''haima'' for blood and ''anthos'' for flower; ''coccineus'' is the Latin word for red or scarlet. In the Afrikaans language it is known as bergajuin, bloedblom, and many other vernacular names.PlantZAfrica.com accessed 11.11.2011 Distribution ''Haemanthus coccineus'' is widespread throughout the winter rainfall region in Southern Africa - from the southern parts of |
John Hutchinson (botanist)
John Hutchinson, OBE, FRS (7 April 1884 Blindburn, Northumberland – 2 September 1972 London) was an English botanist, taxonomist and author.''A Botanist in Southern Africa'' John Hutchinson (London, 1946) Life and career Born in Blindburn, Wark on Tyne, Northumberland, England, he received his horticultural training in Northumberland and Durham and was appointed a student gardener at Kew in 1904. His taxonomic and drawing skills were soon noticed and resulted in his being appointed to the Herbarium in 1905. He moved from assistant in the Indian section to assistant for Tropical Africa, returning to Indian botany from 1915 to 1919, and from then on was in charge of the African section until 1936 when he was appointed Keeper of the Museums of Botany at Kew. He retired in 1948 but continued working on the phylogeny of flowering plants and publishing two parts of ''The Genera of Flowering Plants''. John Hutchinson proposed a radical revision of the angiosperm classification sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Of Good Hope
The Cape of Good Hope ( af, Kaap die Goeie Hoop ) ;''Kaap'' in isolation: pt, Cabo da Boa Esperança is a rocky headland on the Atlantic coast of the Cape Peninsula in South Africa. A common misconception is that the Cape of Good Hope is the southern tip of Africa, based on the misbelief that the Cape was the dividing point between the Atlantic and Indian oceans, and have nothing to do with north or south. In fact, by looking at a map, the southernmost point of Africa is Cape Agulhas about to the east-southeast. The currents of the two oceans meet at the point where the warm-water Agulhas current meets the cold-water Benguela current and turns back on itself. That oceanic meeting point fluctuates between Cape Agulhas and Cape Point (about east of the Cape of Good Hope). When following the western side of the African coastline from the equator, however, the Cape of Good Hope marks the point where a ship begins to travel more eastward than southward. Thus, the firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the Season, solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions of Earth, polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbaceous
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the p ...

Understory

English serves as the medium of inter-Commonwealth relations. Many ...), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In Temperate broadleaf and mixed forest, temperate deciduous forests, many understory plants start into growth earlier in the year ...

International Code Of Nomenclature For Algae, Fungi, And Plants
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alan Meerow
Alan W. Meerow is an American botanist, born in New York City in 1952. He specializes in the taxonomy of the family Amaryllidaceae and the horticulture of palms and tropical ornamental plants. He also works on the population genetics and molecular systematics of cycads and palms. He studied at the Bronx High School of Science and then at the University of New York. Dropping out after a year, aged 19, he moved to Santa Cruz, California. After living on a farm for four years he decided to resume his studies in botany and horticulture at the University of California. Initially his interest in botany was focused on trees, working for three years in the arboretum of the University. He graduated in December 1978 and continued his postgraduate study at the University of Florida, after working for two years at the Marie Selby Botanical Gardens in Sarasota, Florida, where his interest in Amaryllidaceae was stimulated. His master's thesis, in 1983, was on the taxonomy of the genus '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
