Baccharis

Baccharis /ˈbækərɪs/[2] is a genus of perennials and shrubs in the aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as "groundsel bush", and in fact Baccharis is in the same family as the true groundsels, Senecio.

Baccharis, with over 500 species, is the largest genus in the Compositae.[3] It is found throughout the Americas, distributed mainly in the warmer regions of Brazil, Argentina, Colombia, Chile and Mexico,[4] with B. halimifolia ranging northward along the Atlantic Coast to the southern tip of Nova Scotia in Canada.[5]

If present, the leaves of Baccharis are borne along the stems in alternate fashion. Flowers are usually white or pinkish. There are no ray flowers, but many disk flowers (which are staminate) and pistillate flowers.

Some species of Baccharis are toxic to animals; in particular, consumption of B. coridifolia may lead to necrosis in the gastrointestinal tract of cattle, horses, sheep, and rabbits.

Classification [edit]

Baccharis is related to the genera Archibaccharis and Heterothalamus.[6]

The genus Baccharis is named after Bacchus (Dionysus), the Roman god of wine.

Ecology [edit]

Baccharis species are used as food plants by the larvae of some Lepidoptera species, such as the swift moths Phymatopus californicus and P. hectoides. Those of the leaf-miner moths Bucculatrix dominatrix and B. seperabilis feed exclusively on Bush Baccharis (B. pilularis), B. ivella has been found on Eastern Baccharis, and B. variabilis is a polyphagous species which has been recorded on various Baccharis. The Coleophora case-bearers C. linosyridella and C. viscidiflorella are polyphagous species whose larve have been recorded on the Bush Baccharis as well as other plants. Caterpillars of the owlet moth Schinia ocularis feed exclusively on Broom Baccharis (B. sarothroides).

Uses [edit]

Several species of Baccharis are of interest for cultivation, as the dense but flexible stem structure makes for a good windbreak.

Plants of this genus are rich in terpenes, and some are used in native or folk medicine. One that has been specifically described from Chilean Baccaris is viscidone.

Baccharis flowers are rich in nectar, and several species are good honey plants. Particularly B. dracunculifolia is highly esteemed by beekeepers.

Conservation [edit]

A few Baccharis species (especially from the northern Andes) are almost extinct due to habitat destruction. The northernmost occurrence of B. halimifolia, in Nova Scotia, Canada, is also receiving conservation attention.[5]

Invasiveness [edit]

Some Baccharis species, particularly Eastern baccharis (B. halimifolia), have become invasive weeds in places such as Australia and Spain, where they are not native..

Selected species [edit]

Formerly placed in Baccharis [edit]

The following species are among the many that were considered to belong within Baccharis but are now classified in other genera:
