Pityopsis Nuttall. Grass-leaved Golden-aster.

Contributed by Alan S. Weakley, Edwin L. Bridges, & Bruce A. Sorrie

Key to Pityopsis

A genus of about 13 taxa (variously recognized at species or varietal rank), perennial herbs, of se. North America south to Central America. Pityopsis is taxonomically and nomenclaturally difficult. The problems include species and varietal concepts in a morphologically and cytologically diverse group, nomenclatural issues involving typification and application (and frequently misapplication) of a plethora of names at specific and varietal ranks, in three genera: a narrow Pityopsis, a broader Chrysopsis, or a very broad Heterotheca.
