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 botany, botanist and phytogeography, 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 (other), 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 Old Botanical Garden of Göttingen University, 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 Type (biology), types of species described by him, are housed ... [...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. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds 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 (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...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 ...

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.
