 pane/flora, Choisy ?) New Mexico, Fendler, no. G44, also Wright, 

 no. 1584. "Colorado," Hayden. — The seeds in this widely diffused 

 species are well marked, being so coarsely pitted that five or six pits 

 fill the whole girth ; and the thick obtuse edges of, or elevated por- 

 tions between, the pits appear likewise to be minutely rugose under a 

 strong lens.

 .... — Mexico. The principal specimens I have seen (Sierra Mad re, 

 Seemann) seem distinct enough from the foregoing, which, however, 

 Kunth's figure too much resembles. He figures, but does not describe, 

 the seeds as smooth.
