sepalis lanceolato-subulatis, Eocky ravines near El Paso, April — May. (No. 1668, Wright.) 

 Plant 1-2 feet high. Leaves l|-2 inches long, and from less than a line to 2^ lines wide. 

 Corolla blue ; lobes of the limb about one-fourth the length of the tube. Pods as in the two 

 preceding species. No. 1671 Wright is a variety with very narrow leaves, which are scabrous 

 with short hairs on the margin. ■ 



Haplophyton cimicidum^ Decaisne in DC. Prodr. 8, p. 412? In crevices of rocks, Magdalena, 

 Sonora ; Thurber, Schott. (No. 1666, Wright.) Stems several from a woody base, ^1-2 feet 

 high, minutely pubescent. Leaves 1-1| inch long, and 2|-4 lines wide, opposite or alternate, 

 scabrous with short rigid hairs, which stand on a swollen crustaceous base. Flowers terminal 

 solitary or 2-3 in a cymule. Calyx | the length of the corolla-tube ; no traces of glands. Corolla 

 sulphur- yellow, somewhat salverform ; the tube shorter than the obovate lobes. Stamens united 

 about middle of the tube of the corolla; anthers oblong, rather acute, rather longer than the 

 free portion of the filaments. Ovaries oblong, distinct, each 7-8-ovuled ; style rather stout. 

 Stigma oblong-capitate, entire. Pods 2 inches long, very slender, tapering to a long narrow 

 point. Seeds oblong-linear, the testa wrinkled, each extremity furnished with a coma of white 

 hairs, which are longer than the body of the seed. This genus was founded on a Mexican plant ; 

 and part of the character, especially what relates to the seed, is drawn from an unpublished figure 

 of Mocino and Sesse. Notwithstanding the seed is said to be hairy only at the upper extremity, 

 I strongly suspect that the coma of the lower end had become detached, as it is very deciduous. 

 Our plant agrees in every respect with H. cimicidum, except that the latter is said to have leaves 

 2-2A inches Ions and 8-10 lines wide.
