Zeltnera Trichantha
''Zeltnera trichantha'' is a species of flowering plant in the family ''Gentianaceae''. It is referred to by the common name alkali centaury. It is endemic to northern California. Description ''Zeltnera trichantha'' plants are up to 45 cm tall with ovate to lanceolate leaves up to 4 cm long. The inflorescence is flat topped and densely packed with small but showy pink flowers with five petals and a yellow to white throat. Range and habitat ''Zeltnera trichantha'' is native to northern California, mostly in coastal hills and mountains and occasionally in the foothills of the Sierra Nevada. It often grows in alkaline vernal pools and saline flats, sometimes on serpentine soils. References trichantha ''Columnea'' is a genus of around 200 species of epiphytic herbs and shrubs in the family Gesneriaceae, native to the tropics of the Americas and the Caribbean.

August Grisebach
August Heinrich Rudolf Grisebach () was a German botanist and phytogeographer. He was born in Hannover on 17 April 1814 and died in Göttingen on 9 May 1879. Biography Grisebach studied at the Lyceum in Hanover, the cloister-school at Ilfeld, and the University of Göttingen. He graduated in medicine from the University of Berlin in 1836. He undertook expeditions to Provence, Turkey, the Balkans, and Norway. In 1837 he became associate professor and in 1847 full professor at the medical faculty in Göttingen and was named director of the botanical garden there in 1875. While his main fields of interest were phytogeography and systematics, especially the Gentianaceae and Malpighiaceae, he considered his ''Flora of the British West Indian Islands'' his most important work. Much of his collection, especially the types of species described by him, are housed at the Göttingen University Herbarium. His taxonomic classification is set out in his ''Grundriss der systematisc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gentianaceae
Gentianaceae is a family of flowering plants of 103 genera and about 1600 species. Etymology The family takes its name from the genus '' Gentiana'', named after the Illyrian king Gentius. Distribution Distribution is cosmopolitan. Characteristics The family consists of trees, shrubs and herbs showing a wide range of colours and floral patterns. Flowers are actinomorphic and bisexual with fused sepals and petals. The stamens are attached to the inside of the petals ( epipetalous) and alternate with the corolla lobes. There is a glandular disk at the base of the gynoecium, and flowers have parietal placentation. The inflorescence is cymose, with simple or complex cymes. The fruits are dehiscent septicidal capsules splitting into two halves, rarely some species have a berry. Seeds are small with copiously oily endosperms and a straight embryo. The habit varies from small trees, pachycaul shrubs to (usually) herbs, with ascending, erect or twining stems. Plants are usually rhiz ...

Zeltnera
''Zeltnera'' is a genus of flowering plants in the gentian family. It was erected in 2004 when the genus ''Centaurium'' (the centauries) was split. Genetic analysis revealed that ''Centaurium'' was polyphyletic, made up of plants that could be grouped into four clades. Each became a genus. ''Centaurium'' remained, but it is now limited to the Eurasian species. The Mexican species now belong to genus '' Gyrandra'', and the Mediterranean and Australian plants are in genus '' Schenkia''. The new name ''Zeltnera'' was given to this genus, which contains most of the North American centauries. There are about 25 species.Mansion, G.
