Conyza (Asteraceae): A critical evaluation based on populations in Catalonia, Spain
DOI:
https://doi.org/10.3989/collectbot.2020.v39.005Keywords:
Catalonia, Compositae, Conyza, Erigeron, Iberian Peninsula, keys, synonyms, taxonomyAbstract
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.
