Trilisa Cassini. Common name: Trilisa.
A genus of 3 species, perennial herbs, endemic to the Southeastern Coastal Plain of North America. The genus name is an anagram of Liatris, as is Litrisa. Schilling (2011b) showed that Trilisa and Litrisa should be separated from Carphephorus, unless an alternate solution is pursued of either additional splitting, or lumping Liatris, Carphephorus, Litrisa, and Trilisa.
Tribe: Eupatorieae. Subtribe: Liatrinae.ID notes: Trilisa can be distinguished from Carphephorus by its smaller heads (involucres 3.5-6 mm high vs. 6-15 mm high), fewer phyllaries per head (6-12 vs. 15-40), and lack of shining resin dots on the leaves (Carphephorus has numerous resin dots).

- If you opt out of including email, please be as specific as possible (e.g., which photo is incorrect?)
- Please do not submit questions asking to identify plants or about horticultural topics (e.g., how do I control an invasive plant in my garden?). Instead, those questions can be submitted here for the Carolinas region only.
- Please do not send us feedback about unkeyed species as this work is ongoing.
- Please allow time for flora edits to show in our next data release. We greatly appreciate your feedback but may require extra time to research complicated taxonomic issues.
