Nuttall’s description in the roughness of 
the leaves, but that author had evidently 
only a single imperfect specimen. . The 
species is intermediate between G. pedun 
cularis and G. tenuifolia, y., distinguished 
from the former by the slender stems and 
filiform leaves, often but not always fas- 
cicled, from the latter by the large flowers, 
long peduncles, &c

Has. Texas, Saeed (3rd Coll. n. 
294.). (v. s. sp.) 
This plant has sometimes almost the fo- 
liage and aspect of G. heterophylla, with 
the corolla of G. tenuifolia but larger, the 
peduncles are nearly as long as in G. fili- 
folia. The anthers are very woolly as in 
G. tenuifolia.

The ave yarieties may, perhaps, be 
species, especially the last, but the charac- 
ters are very slight. They all differ from 
uncularis by the glabrous, scarcely

short capsule and habit; from G. longifolia
