Traubiinae
'' Phycella cyrtanthoides'' Traubiinae is a subtribe of plants classified under the tribe Hippeastreae. It belongs to the subfamily Amaryllidoideae of the Amaryllis family ( Amaryllidaceae). Description Bulbous perennial herbaceous plants, terrestrial in habitat. Leaves linear or lorate, annual, sometimes hysteranthous. Taxonomy The term was originally used by the Müller-Doblies' in 1996 as a monotypic subtribe of Hippeastreae, to include ''Traubia'', based on Traub's original use of Traubeae for the same purpose. Created from a redistribution of genera of Hippeastreae following a molecular phylogenetic study it is composed of the following genera, based on the presence of lorate-leaves rather than petiolate, which form the remaining genera of the tribe Hippeastreae, ''i.e.'' Hippeastrinae. In this redistribution the four species of ''Famatina'' were polyphyletic and ''F. maulensis'' segregated with ''Phycella'' and was consequently transferred: The generic d ...

Hippeastreae
Hippeastreae is a tribe of plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae). Species in this tribe are distributed in South America. Flowers are large and showy, zygomorphic, with the stamens in varying lengths, inflorescence bracts are often fused basally (along one side). The seeds are flattened, winged or D-shaped. Reported basic chromosome numbers are ''x''= 8-13, 17, and higher. All the species in this tribe present a remarkable aesthetic interest and horticultural value. Taxonomy Meerow et al. (1999) provide a history of the treatment of the genera of Amaryllidaceae, including Hippeastreae, from the mid-twentieth century. While morphological phylogeny has been frustrated by the perversive homoplasy typical of the Amaryllidaceae, application of molecular phylogenetics to the Amaryllidaceae did not indicate clear tribal divisions but rather broad biogeographical clades. However the American clade resolved the tribe Hippeastreae. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Hippeastrinae
Hippeastrinae is a subtribe of plants classified under the tribe Hippeastreae. It belongs to the subfamily Amaryllidoideae of the Amaryllis family ( Amaryllidaceae). Description Terrestrial bulbous perennial herbaceous plants, although three species of ''Hippeastrum'' are epiphytic. The leaf shape is linear, lorate, or lanceolate (''Eithea'' has oblanceolate-petioled leaves). The leaf growth pattern is annual or persistent, and often histeranthous. Their texture is firm, and they are moderately canaliculated internally. The scape is hollow and the spathe has two bracts which may be fused or free. The inflorescence may have between one and thirteen flowers. The flowers, which may be sessile or pedicellate have a perigone that is actinomorphic to highly zygomorphic, and is tubular, campanulate or infundibulorm in shape. The tepal-tube may vary from obsolete to being more than half the length of the perigone. When a paraperigone is present it consists of basal appendag ...

Phycella
''Phycella'' is a genus of herbaceous, perennial bulbous flowering plants belonging to the family Amaryllidaceae, subfamily Amaryllidoideae. The genus consists of five species distributed from central Chile to northwestern Argentina. Taxonomy The genus was described by John Lindley in 1825. After further examining specimens of ''Amaryllis ignea'' (see illustration) that he had described the previous year as ''Amaryllis'', with some reservation, Lindley concluded they were a separate genus, naming two species, ''P. ignea'', and ''P. cyrtanthoides'' (previously ''A. cyrtanthoides''). Subsequently, it was considered these were the same plant, and ''P. ignea'' was reassigned to a synonym for ''P. cyrtanthoides''. Phylogeny ''Phycella'' is located in the American (Hippeastroid) clade of the Amaryllidoideaetribe, where it is placed in tribe Hippeastreae, subtribe Traubiinae. In molecular phylogenetic analysis, ''Phycella'' forms a sister group to the remainder of the Hippeastre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhodolirium
''Rhodolirium'' is a small South American genus in the tribe Hippeastreae of the family Amaryllidaceae. Although originally described by Philippi in 1858 it has long remained buried in other taxa, principally ''Hippeastrum'' and more recently ''Rhodophiala''. Only in recent years has it been rehabilitated. Restoring the genus was first proposed by Naranjo & Poggio (2000), and accepted by Ravenna in 2003, although he used the name '' Rhodolirion'', originally used by Baker (1878) in his very broad construction of ''Hippeastrum'' including both ''Rhodophiala'' and "''Rhodolirion''". He also renamed '' Rhodolirium andinum'' as ''Hippeastrum rhodolirion''. Later he elevated ''Rhodolirion'' to the status of subgenus, with ''H. rhodolirion'' (subsequently '' Rhodophiala rhodolirion'') as the type species . Subsequently the genus has been treated as part of ''Rhodophiala''. Description Flowers single or pluriflor, perigone infundibular (funnel shaped) with elongated floral tube. ...

Famatina (plant)
''Famatina'' was a small genus of South American bulbous plants identified by the Chilean botanist Ravenna in 1972. Five species have been described. Molecular phylogenetic studies suggested the genus was polyphyletic, and species have been moved to other genera. Taxonomy Molecular phylogenetic studies suggested the genus was polyphyletic. Of four species examined, one (''F. maulensis'') segregated in a clade together with members of the Traubiinae subtribe, while the remaining three (''F. andina'', ''F. cisandina'', and ''F. herbertiana'') segregated with members of subtribe Hippeastrinae. The first species is now placed in the genus ''Phycella'', the others in the genus ''Zephyranthes''. Subdivision Described species: * ''Famatina andina'' (Phil.) Ravenna – synonym of ''Zephyranthes tenuiflora'' * ''Famatina cisandina'' Ravenna – syn. of ''Zephyranthes cisandina'' * ''Famatina herbertiana'' (Lindl.)

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...
