 HOSACKIA HA70UNI Orcutt. 



''Suffrutescent, 6-i2 / high or more, 

 the slender stems woody at base, at first 

 slightly spreading, then recurving in- 

 ward and slightly intertwining, forming a 

 loosely-compact bush, glabn us or near- 

 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, )4r l A 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]/ z • 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, 1S89, growing among the 

 rocks in a canyon leading into the : do- 

 rado desert, on the old stag t line from 

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

 bra, Torrey, this plant is commonly 

 known as deer w«-ed, 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. 

 SYRMATIUM DESDR- tIDEUM Greene. 



"Shrubby, erect, 4-7° high, with roughish 

 brown stern an inch or 2 in thickness, & m any- 

 short ascending branches: branch lets angular, 

 their growing parts more or less minutely 

 appressed-silky, the plant otherwise glabrous: 

 leaflets 3, narrowly oblong, obtuse: umbels 

 numerous, on short peduncles, not bracted: 

 calyx 3—1" long, the triangular-subulate teeth 

 34 as long as the nearly cylindrical tube: corol- 

 la 4-6" long: pod %' long, slightly curved, 3- 

 seeded: seeds terete & straight. Hill tops, 



among other bushes, on the higher parts of 

 Santa Ciuz Island. Near S gla'orum, but of 



entirely different habit, with much larger fis 

 & fruit, on shOit, rigid, crowded branchlets."

 Br Ca ac pr II 1 208, who says:— 'Some of its 

 forms are exactly the mainland plants."
