of Yernal radiate plants near to Ga - 
Urdia'i in the barrens or glades of 
West Kentucky and W. Tennessee,

114. Lophactis FJ. G. by C. S. Ra- 
FINESQUE. 
I noticed in 1818 this plant on the 
Wabash, but out of blossom, in 
1821. Dr. Ward brought me a per-

ana. It is also a N. G. of radiate 
plant near the Vernasolis , Leptopo- 
da and Balduinia. The name means 
crested rays.
