Flaveria Juss. (Compositae), a newly naturalized genus in

Abstract

Abstract:

Flaveria bidentis (L.) Kuntze, a newly naturalized genus and species of Compositae form Hebei and Tianjin, China, is described and illustrated. Flaveria Juss. is related to Tagetes L. and Gaillardia Fouger. in having phoranthium without chaffy bracts, but differs by having leaves opposite and decussate, base usually connate, capitula aggregated in flat-topped corymbose panicles or glomerulelike synflorescences in the apex of the branches, flower yellow, ligule floret 1 (rarely 2), pappus absent.

Key words: Flaveria, naturalized genus, Flaveria bidentis, Compositae, China.
