Pappus (flower Structure)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a dispersal mechanism for the achenes that contain the seeds. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or '' Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. In genera such as '' Bidens'' the pappus has hooks that function in mechanical dispersal. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an '' Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a vital role in the wind-aided dispersal of its seeds. By creating a separated vortex ri ...

Iodocephalopsis
Vernonieae is a tribe of about 1300 species of plants in the aster family. They are mostly found in the tropics and warmer temperate areas, both in the Americas and the Old World. They are mostly herbaceous plants or shrubs, although there is at least one tree species, ''Vernonia arborea''. Taxonomy Vernonieae is considered sister to the tribe Liabeae. The tribe originated in southern Africa or Madagascar, and spread to the Americas in at least two different events. In many works some 80% of the species in this tribe are classified in the genus ''Vernonia''. Other authors, like Harold E. Robinson, divide the tribe into a larger number of small genera.

Vernonia
''Vernonia'' is a genus of about 350 species of forbs and shrubs in the family Asteraceae. Some species of this genus are known as ironweeds. Some species are edible and of economic value. They are known for having intense purple flowers. There have been numerous distinct subgenera and subsections named in this genus, and some botanists have divided the genus into several distinct genera. For instance, the ''Flora of North America'' recognizes only about twenty species in ''Vernonia'' ''sensu stricto'', seventeen of which are in North America north of Mexico, with the others being found in South America. Taxonomy The genus was circumscribed by Johann Christian Daniel von Schreber in Gen. Pl. ed. 8 vol.2 on page 541 in 1791. The genus name of ''Vernonia'' is in honour of William Vernon (1666/67 - ca.1711), who was an English plant collector, ( bryologist) and entomologist from Cambridge University, who collected in Maryland, USA in 1698. Species Species of this genus are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
