| Abstract: | A new species,Erigeron astranthioides, apparently endemic to the Sierra Madre of central Durango, is described and illustrated. It is contrasted withE. forreri (Greene) Greene andAstranthium, both of which are similar, though apparently through convergence. The new species is part of a lineage that includes six other primarily epapposeErigeron species mostly from the western Sierra Madre; within this group its closest relative appears to beE. mimus (S. F. Blake) Nesom, with which it is compared. |
