Phycella Herbertiana
''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] |

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Herb
In general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. ''Herbs'' generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while ''spices'' are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits. Herbs have a variety of uses including culinary, medicinal, aromatic and in some cases, spiritual. General usage of the term "herb" differs between culinary herbs and medicinal herbs; in medicinal or spiritual use, any parts of the plant might be considered as "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin and pericarp. The word "herb" is pronounced in Commonwealth English, but is common am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhodophiala
''Rhodophiala'' was a genus of herbaceous, perennial and bulbous plants in the Amaryllis family (Amaryllidaceae, subfamily Amaryllidoideae). It consisted of about 30 South American species distributed in southern Brazil, Argentina, and, specially, in Chile. Most of the species are known colloquially as ''añañuca''. It has now been submerged in ''Zephyranthes''. Description ''Rhodophiala'' species resemble small-flowered ''Hippeastrum'' or multiflowered ''Habranthus'' species. Their narrow parallel-sided leaves are unlike that of ''Hippeastrum'', more closely resembling that of ''Habranthus'' or ''Zephyranthes''. Taxonomy At one stage, ''Rhodophiala'' was considered a subgenus of the closely related ''Hippeastrum''. Although as of February 2016 not yet accepted by the World Checklist of Selected Plant Families a number of species of ''Rhodophiala'' have been rehabilitated as ''Rhodolirium''. Species The World Checklist of Selected Plant Families accepts 27 species :Search ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Segregated (taxonomy)
In taxonomy, a segregate, or a segregate taxon is created when a taxon is split off from another taxon. This other taxon will be better known, usually bigger, and will continue to exist, even after the segregate taxon has been split off. A segregate will be either new or ephemeral: there is a tendency for taxonomists to disagree on segregates, and later workers often reunite a segregate with the 'mother' taxon. If a segregate is generally accepted as a 'good' taxon it ceases to be a segregate. Thus, this is a way of indicating change in the taxonomic status. It should not be confused with, for example, the subdivision of a genus into subgenera. :For example, the genus ''Alsobia'' is a ''segregate'' from the genus ''Episcia''; The genera ''Filipendula'' and ''Aruncus'' are segregates from the genus ''Spiraea''.

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.)
