ly so throughout: leaflets 3 or less, ob- 

 long, obtuse, 1-2 mm. long: fl. single or 

 more rarely in pairs, short pedunculate, 

 2 mm. long: calyx of equal length, the 

 teeth narrowly subulate, erect, %rYi as 

 long as the tube: pod but slightly in- 

 curved, usually twice the length of the 

 persistent calyx, i-seeded: seed dark 

 olive-green, 2# mm. long, slightly 

 curved. I take pleasure in dedicating 

 this delicate species to Mr. Marion D. 

 Haydon, in return for his hospitality and 

 for his directing my attention to various 

 forage plants whose valuable qualities 

 had previously been unsuspected. Col- 

 lected in April, 1889, growing among the 

 rocks in a canyon leading into the Colo- 

 rado desert, on the old stage line from 

 San Diego to Ft. Yuma. With H. gla- 

 bra, Torrey, this plant is commonly 

 known as deer weed, but its smaller 

 growth will render it less valuable for 

 cultivation and it is apparently too limi- 

 ted in its distribution to assume import- 

 ance as a wild forage plant." Orcutt, 

 West American Scientist, vi. 63, Jl 1889.
