face, hrcridlv obovate, 7 uiiii. wide when spicad oiil, the sidc-s 

 turned back and probably parallel; wino^s apparently entirely 

 coverinj^^ the keel, 5 mm. (kep; keel stronjj^ly curved. 



Tlie de.scription and illu^tration.s are from Parry 41, col- 

 lected near St. Georjje, Utah, in 1874, the specimen in the her- 

 barium of the Mi.s.sonri Hotanical Garden. Thi"^ is part of the 

 tvpe coljecliou. Dr. Rvdberg^ cotnpares this with L pusi//iis, 

 but the habit and aspect is different. .-X remarkable feature of 

 this species is that the stipules are more nearly free than in anv 

 related species. 



L. riihois has been collected at least once in Nevada. 

 Goodding 22j4a from Dry Lake, Clark county, di-^tributed as L. 

 pusillus, is this specie.s. It is orrouped with the subo^en us /*/<?/)/- 

 carpos. vSiuce none of the Great Bai^in and interior species 

 are strictly typical, I now propose a new section for thein, whicli 

 may bear ihe name Prsii.i.l, from the f)ldest species in the sec- 

 tion. They ha\e medium sized connate cotyledons with entire 

 edges, scattered, nsuall\- \iolet flowers wliich are shaped iniich 

 like those of t\pical Lupinus, the calyx lobes both g-reen, the 

 upper one usualh; well developed; pods ovate or elongated, and 

 sometimes more than 2-seeded.
