Tetrachondra Hamiltonii
''Tetrachondra'' is a plant genus and a member of the family Tetrachondraceae. It comprises two species of creeping succulent, perennial, aquatic or semi-aquatic herbaceous plants. Its distribution range is disjunct: one species is endemic to New Zealand (mainly Stewart Island, Otago and Southland) while the other one is endemic to southern Patagonia and Tierra del Fuego. These plants bear essential oils. Description Leaves The leaves stem short and erect from prostrate rooting stems. They are simple, opposite leaves, with aromatic glands and no stipule. The leaves are connate by flattened petioles. The lamina is simple, minutely denticulate on the margin, and leathery on the surface. Flower Flowers are solitary and can be axillary or terminal. They are tetramerous, without free hypanthium. There are a distinct calyx, which consists of 4 fused sepals, and a distinct corolla, consisting of 4 fused petals. The androecium consists of 4 free, epipetalous stamens, all of which ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polypremum
''Polypremum'' is a flowering plant genus in the family Tetrachondraceae. The genus contains the single species ''Polypremum procumbens'', commonly known as juniperleaf or rustweed. ''Polypremum'' has also been placed in the various families Buddlejaceae, Loganiaceae, Rubiaceae The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules ..., and most recently in its own Polypremaceae. ''P. procumbens'' is a perennial or annual forb/herb, and grows low with sometimes multiple ascending stems producing small white flowers that bloom in summer and fall. Leaves are opposite, 1–2.5 cm, narrow, and pointed at the end. The foliage turns a brownish red in autumn. ''P. procumbens'' is native to eastern USA excluding New England, south to Central America and the West Indies, with occurrences i ...

Richard Wettstein
__NOTOC__ Richard Wettstein (30 June 1863 in Vienna – 10 August 1931 in Trins) was an Austrian botanist. His taxonomic system, the Wettstein system, was one of the earliest based on phyletic principles. Wettstein studied in Vienna, where he was a disciple of Anton Kerner von Marilaun (1831-1898) and married his daughter Adele. He was a professor at the University of Prague from 1892, and at the University of Vienna from 1899. He newly laid out the Botanical Garden of the University of Vienna. In 1901 he became president of the Vienna Zoological-Botanical Society (''Zoologisch-Botanische Gesellschaft''), and during the same year took part in a scientific expedition to Brazil. In 1919 he was appointed vice-president of the Vienna Academy of Sciences. During his later years (1929–30), he traveled with his son, Friedrich, to eastern and southern Africa. The mycological genus ''Wettsteinina'' is named in his honor and also '' Wettsteiniola'', which is a genus of flowering plants ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
