WEAKLEY'S FLORA OF THE SOUTHEASTERN US (4/14/23):
Pityopsis aspera var. adenolepis
FAMILY
Asteraceae
Go to FSUS key
Dig deeper at SERNEC, a consortium of southeastern herbaria.
The genus Pityopsis has been split from Chrysopsis (the golden-asters) and from Heterotheca (camphorweeds) by the silky, silvery, appressed hairs on leaves and stems. Read more at Vascular Plants of North Carolina.
Nesom in Taxonomic synopsis of Pityopsis (Asteraceae) (2019) subsumes this variety under a more broadly defined P. aspera, since he did not find a clear morphological or geographic separation between these varieties. We are tentatively maintaining the varieties, pending further field study, per Weakley's Flora (2023).
