 vania. Tennessee, and California."

A large patch of this species was noted near the railroad in 

 the vicinity of Lake Charles. The same plant has also been col- 

 lected by the writer near Slidell. Not otherwise known from 

 Louisiana. Previous known distribution, acording to Small, 

 ""Florida to Texas, New ^Mexico, and tropical America." 



Houstonia An gusti folia Michx.

 plorers, as in the prairies around Lake Charles it is one of the 

 most abundant species. Range : according to Small, ' ' Illinois to 

 Kansas, Florida, and Texas."
