When working on Hymenoxys, I had occasion to examine 
Syntrichopappus lemmoni Gray, and concluded that it ought to 
be separated from Syntrichopappus as a distinct genus, thus: 
/ Microbahia gen. nov. 
Close to Syntrichopappus, but pappus entirely absent: rays 
rose-purple without yellow: leaves entire. 
Microbahia lemmoni (Gray) 
Actinolepis lemmoni Gray, Proc. Am. Acad. 16: 103. 188r. 
Syntrichopappus lemmoni Gray, Proc. Am. Acad. 19: 20.
