Vernonia Serratuloides
''Vernonia'' is a genus of about 350 species of forbs and shrubs in the Daisy family Asteraceae. Some species are known as ironweed. 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 found in ...

Vernonia Arkansana
''Vernonia arkansana'' (also known as Arkansas ironweed and great ironweed) is a species of perennial plant from family Asteraceae found in south-central United States. The plant is high and wide. The flowers bloom from August to September and are pink-purple coloured. The cultivar 'Mammuth' is a recipient of the Royal Horticultural Society's Award of Garden Merit. Ecology The plant is pollinated by various insects such as bees, butterflies, and skippers. The same fauna representatives also collect nectar. Bees like '' Melissodes vernoniae'' are frequent visitors to ''Vernonia'' plants in general. Another special guest the species attracts is ''Aphis vernoniae'', an aphid that prefers to suck on juice of the species. Various caterpillars of moths also enjoy the feeding. Birds on the other hand, don't feed on it, due to hard seeds, and small amount of pollen left (for hummingbird Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ...
