Symphyotrichum texanum (E.S. Burgess) Semple. Common name: Texas Aster. Phenology: Aug-Oct. Habitat: Limestone cliffs, sandstone cliffs, bluffs. Distribution: MO and KS south to LA and TX; disjunct east of the Mississippi River in e. LA, e. MS, and w. and c. KY; Mexico (COA).

ID notes: The distinctive cordate (heart-shaped) basal and cauline leaves bearing serrate-crenate margins combined with the relatively short ray florets surrounding disc florets that tinge an almost watermelon-pink at anthesis make this one of the easiest Symphyotrichum to identify in eastern TX (Aidan Campos, pers.comm. 2021).

Origin/Endemic status: Native

Taxonomy Comments: Sometimes treated as a variety or lumped under S. drummondii; characters used to separate the two are variable and further taxonomic work is needed to clarify distributions.
