Plantce Lindheimeriance. 251 



Industry. June — August. Also, in Drummond's Texan 

 Collection. Stems six to sixteen inches high, from a very 

 thick perpendicular root. Leaves mostly broadly oval, and 

 obtuse. Flowers large and greenish : calyx pubescent, one- 

 third the length of the corolla. Follicles ovate-lanceolate, and 

 with a long acumination, " 8-angled, the angles often some- 

 what tuberculated ; the outer one furnished with soft spines, 

 or a dentated crest." Undheimer. This species is nearly 

 allied to A. longicornu, Benth., which we find has a similar 

 gynostegium, only a little more decidedly 3-lobed at the apex, 

 as well as a bifurcated horn, both lobes of which are shorter 

 than in our species. There is also a bifurcated horn in 

 A. obtusifolia.

 in open woods, near Industry. April — June. (Also, No. 190 

 and 203 of Drummond's second, and 237 of the third Texan 

 collection.) Stems 6 to 15 inches high, diffuse ; leaves 1-2 

 inches long, cordate, with an open sinus, the uppermost some- 

 times almost truncate at the base. Corolla greenish purple, 

 about two lines in diameter. The fleshy lobes of the cup- 

 shaped coronas are furnished in the middle with a small pro- 

 cess, which is connected at the base with the mid-nerve of 

 the anther, and is free and incurved at the obtuse point, the
