Conyza (Asteraceae): una valoración crítica basada en las poblaciones de Cataluña, España

Conyza (AsterAceAe): A criticAl evAluAtion bAsed on populAtions in cAtAloniA, spAin.— The genus Conyza is examined with a view to providing a fresh look at its diversity and classification in NE Spanish territory, Catalonia in particular. Each taxon is briefly described and commented on, and a new key including both past and extant species has been elaborated. Two infraspecific taxa: C. canadensis var. glabrata and C. bonariensis var. angustifolia, formerly largely ignored, have been recognised, and the identity and status of other taxa occasionally recorded from the region is also discussed.
