* Annuals of the Old World, sparingly and locally adveutive, not enough so to count as

 P.* Californicum, Gray.^ Very much like P. dulmtm, but hairs scanty, much finer: 



jictals saffron or more red, with lemon-colored or greenisli eye toward the base : capsule 



(about half inch long) clavate-turbinate, 6-11-merous; dehiscing by dentiform sulxiuadrate 



valves a line long and wide, disclosing the placenta3. — Proc. Am. Acad. xxii. 313; Bran-

1 In the light of Miss Eastwood's notes (Zoe, iv. 4), A. HfsproA, Gray, differs strikingly in the 

 field from the tj'pical A . platyceras, the former being much more densely setose, with, generally 

 much finer spines or bristles, more sessile heads, paler foliage, and less deeply pitted seeds. It is 

 doubted, however, whether these differences are more than varietal, as apparent intermediates occur.
