To the above species, fully described by Agardh, we have the two following to add : — 



24. L. truncates; appresse pubescenti-pilosus demum glaber, foliolis 5-7 linearibus 

 basi angustatis apice bi-tridentatis, stipulis minutis linearibus brevibus, racemis elon- 

 gatis, floribus alternis, bracteis pedicello brevioribus persistentibus, calycis bracteolati labio 

 superiore bipartito inferiore integro (minute tridentato, Nutt.), ovario lineari-oblongo 

 hirsutissimo. — Nutt. mst. — Torr. et Gr. Fl. ined. 



Nearly allied to L. linifolius. Roth ; and an imperfect specimen, in Dr Lindley's collection from Douglas 

 (California), is doubtfully referred to that species by Agardh. But it is truly distinct, in the more truncate 

 leaflets and the much smaller stipules and bracteas, which latter are also persistent. MrNuttall found it at 

 San Diego, N. California, and his name we adopt. Flowers deeply tinged with purple. 



25. L. parvijlorus ; elatus erectus ramosus pubescenti-hirsutus demum glaber, foliolis 

 5-7 obovato-lanceolatis, stipulis minutis subulatis persistentibus, racemis elongatis, flori- 

 bus (parvis caeruleis) subverticillatis, bracteis subulatis pedicellum aequantibus deciduis, 

 calycis sericei labiis suboequalibus superiore bidentato inferiore integro, (legumine birsuto 

 subtrispermo). — Nutt. mst Torr. et Gr. Fl. ined. 



Hab. Between Henry and Smith's Rivers, Snake Country. (Tolmie.} — An exceedingly well-marked 

 species, 1^ to 2 feet high, subglaucous. Leaflets broader upwards, acute or generally very obtuse. Racemes 

 long, slender, of numerous small bluish flowers.
