Rabbitbrush
Rabbitbrush is a common name for shrubs, principally of the western United States, in three related genera of the family Asteraceae: * '' Chrysothamnus'' — about seven species in the United States, including Greene's rabbitbrush * ''Ericameria ''Ericameria'' is a genus of North American shrubs in the family Asteraceae. ''Ericameria'' is known by the common names goldenbush, rabbitbrush, turpentine bush, and rabbitbush. Most are shrubs but one species ''( E. parishii)'' can reach tree ...'' — about six species in the United States, including gray (or rubber) and Parry's rabbitbrush * '' Lorandersonia'' — about four species in the United States, including Bailey's rabbitbrush and spearleaf rabbitbrush Taxonomy for these genera has changed recently; previously, the rabbitbrushes in ''Ericameria'' and ''Lorandersonia'' were included in ''Chrysothamnus''. In each of these genera, not all species are called "rabbitbrush"; most ''Ericameria'', for instance, are cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow Rabbitbrush
''Chrysothamnus viscidiflorus'' is a species of shrub in the family Asteraceae of the Americas known by the common names yellow rabbitbrush and green rabbitbrush. Description ''Chrysothamnus viscidiflorus'' grows up to about in height, with spreading, brittle, pale stem branches. The leaves are up to a few centimeters long and may be thin and thread-like or up to 1 cm wide and oblong. They are glandular, resinous, and sticky. The inflorescence is a bushy cluster of flower heads, each head 0.5–1 cm long. The flower head is lined with sticky yellow-green phyllaries and contains several yellowish protruding flowers. The fruit is a hairy achene a few millimeters long with a wispy pappus at the tip. The species grows in sagebrush and woodland habitat.

Chrysothamnus
''Chrysothamnus'', known as rabbitbrush, rabbitbush, and chamisa, are a genus of shrubs in the family Asteraceae. The native distribution is in the arid western United States, Canada, and northern Mexico. It is known for its bright white or yellow flowers in late summer. ''Chrysothamnus'' may grow up to a tall shrub or subshrub, usually with woody stem bases. The leaves are alternate, sessile or with short petioles, with entire edges. The flowerheads are singular or in clusters. Each composite flower often has five to 6 (though sometimes upwards of 40) yellow disc florets and no ray florets. ''Chrysothamnus'' species are used as food plants by the larvae of some Lepidoptera species including '' Coleophora linosyridella'', '' Coleophora viscidiflorella'' (which have both been recorded on ''C. viscidiflorus'') and '' Schinia walsinghami''. ; Species * '' Chrysothamnus depressus'' – dwarf rabbitbrush, longflower rabbitbrush – California Nevada Arizona Utah Colorado New Mex ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Ericameria
''Ericameria'' is a genus of North American shrubs in the family Asteraceae. ''Ericameria'' is known by the common names goldenbush, rabbitbrush, turpentine bush, and rabbitbush. Most are shrubs but one species ''( E. parishii)'' can reach tree stature. They are distributed in western Canada (Saskatchewan, Alberta, British Columbia) western United States (from the western Great Plains to the Pacific) and northern Mexico. Bright yellow flower heads adorn the plants in late summer. All the species have disc florets, while some have ray florets but others do not. ''Ericameria nauseosa'', (synonym ''Chrysothamnus nauseosus''), is known for its production of latex. Etymology ''Ericameria'' is based on the genus name ''Erica'' and the Greek word ''meros'' ('part'), in reference to the similarity of the plant's leaves to those of ''Erica''. Uses This genus has a number of admirable landscape plants for heavily alkaline soils, but most species need extensive rejuvenation pruning ev ...
