Botany picture #5: Baccharis rhomboidalis

Baccharis rhomboidalis (Asteraceae) from the vicinity of Bariloche, Argentina, 2009. Baccharis is a large genus of shrubby daisies in the Americas. It is considered to be taxonomically very difficult, i.e. many species are hard to identify or tell apart (not this one though). The English Wikipedia, as of this writing, calls it the largest genus of the daisy family with 500 species despite also writing that the genus Senecio has 1250 species. Ah, the joys of crowd-sourcing.
