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 ...

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 ''Apodolirion'' is a genus of herbaceous, perennial and bulbous plants in the Amaryllis family ( Amaryllidaceae, subfamily Amaryllidoideae).

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 alkaloidal ...

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.

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 ...

Clivia Nobilis
''Clivia nobilis'', the green-tip forest lily, is a species of flowering plant in the genus ''Clivia'', of the family Amaryllidaceae, native to South Africa. It grows to about . It has evergreen strap-shaped leaves, and bears pendent umbels of multiple narrow, trumpet-shaped, red and yellow flowers, tipped with green.Nico Vermeulen:"The Complete Encyclopedia of Container Plants", p. 85. Rebo International, Netherlands, 1998. "Botanica. The Illustrated AZ of over 10000 garden plants and how to cultivate them", p. 241. Könemann, 2004. At a minimum temperature of , in temperate regions it is normally cultivated as a houseplant.

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Plant Life Society
The International Bulb Society was founded on May 31, 1933 and is an international society dedicated to informing the public about the science, cultivation, conservation and botany of geophytic plants, commonly known as bulbs. It began in 1933 as the American Amaryllis Society, publishing its first yearbook (''Year Book, American Amaryllis Society'') in 1934. One of its founders was Hamilton Traub, who edited the yearbook in its early days. Two years later (1936) the title was changed to ''Herbertia''. Later the society was renamed the American Plant Life Society, and its yearbook was called ''Plant Life. Amaryllis Year Book''. In 1984 ''Plant Life'' became ''Herbertia'' again. The society became inactive in January 2014. Awards * The Herbert Medal The Herbert Medal is awarded by the International Bulb Society to those whose achievements in advancing knowledge of ornamental bulbous plants is considered to be outstanding.

A Journal Of Systematic And Evolutionary Botany
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), 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 deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...
