 Chod. Monog. ii. 156. t. 21. f. 7-8 (1893). P. setifera Brandeg.!

 Culiacan, 1 Nov. 1904, Brandegee (type coll. of P. setifera: G). 

 T. 2. Fig. 65. From Chodat's full description and figures there 

 can be no doubt of the identity of his P. crinita (types Karwinski 

 303, 304 (hb. Monac.)) with Brandegee's P. setifera. 



111. P. hygrophila HBK. Slender erect annual, simple or 

 slightly branched, glabrous throughout, about 3 ^m. high, the 

 stem narrowly wing-angled. Lowest leaves sub verticillate, linear-
