44. L. microcarpus Sims. 

 Chick Lupine. Plant com- 

 monly 1/2 to 2 feet high, the 

 stem stout, often fistulous, 

 sometimes succulent, simple 

 below and parted at the middle 

 into many spreading branches 

 or sometimes branched from 

 the base ; herbage more or less 

 villous ; leaflets oblanceolate to 

 oblong-oblanceolate, acute or 

 rounded at apex, often mucro- 

 nate, I/2 to 1^/2 inches long; ra- 

 cemes 4 to 10 inches long, on 

 long or short peduncles ; whorls 

 very definite and rather re- 

 mote, sometimes approximate ; 

 bracts setaceous, commonly 

 shorter than the calyx, reflex- 

 ing; pedicels % to 1 line long; 

 flowers 4 to 7 lines long, spreading, after anthesis becoming closely erect ; cal\^ 

 sparingly pubescent, the upper lip scarious, obscurely toothed or cleft, the lower 

 long, toothed; petals rose-pink or lilac to dark purple; keel eiliate near the claw on 

 upper margin, sometimes also on lower margin; pods ovate to oblong-ovate, 6 to 8 

 lines long, long-hairy ; seeds 2, usually minutely granulose. 



Valley flats or hillsides, 5 to 2500 feet: Monterey Co. to Siskiyou Co., thence 

 east to Lassen and Modoc Cos. North to southern and eastern Oregon. Apr.-May. 

 The original material of Lupinus microcarpus Sims came from Chile. While Chilean collec- 

 tions of this species are scanty in North American herbaria, the material before us resembles 

 Californian specimens very closely. In certain cases, if the labels were removed, it would seem 

 impossible, on the basis of the material itself, to say whether a given sheet were Californian or
