Specimens on which this species is founded have been re- 
ferred to both Hedeoma Reverchonit and H. Drummondy7, 
the latter however is so different that it need not be consid- 
ered in this connection; it differs from Hedeoma Reverchonia 
in its widely spreading habit and the copiously divided 
branches. The leaves are only about one-half as large and 
more remote and their blades of an ovate or oval shape as 
compared with a narrowly oblong one. The calyx is only 
one-half as large and lacks the characteristic bristly pubes- 
cence of A. Reverchouiz. 
The original specimens were collected by Mr. Heller, at 
Kerrville, April 25-30, ee and distributed i in his Plants of 
Southern Texas, no. 1663

oles: calices 5-6 mm. tong, hispidulous, surpassed by the 
leaves; tube somewhat swollen; segments of the lower lips
