27. L. douglasii Greene (pi. 80, figs. 1-8). Perennials with long 

 (4 dm.) decumbent branches, long internodes, and peduncled umbels 

 extending along the stems ; stems clothed with short appressed hairs ; 

 leaves and calyces with a somewhat looser pubescence ; largest leaves 

 2 to 3 cm. long ; leaflets 4 or 5, oblanceolate or obovate, usually acute ; 

 umbels several-flowered, the bract when present of one or more 

 leaflets ; flowers 10 to 12 mm. long ; calyx teeth linear-subulate, villous, 

 equal in length to the tube ; blade of the banner oblong, wings oblong, 

 noticeably surpassing the keel ; legumes arcuate, extending well 

 beyond the calyx, canescent, keeled, and attenuately beaked. 



Northern California north to Washington and Idaho. Sonoran 

 and Transition. Distribution Map 9. May-July. Reaches its typical 

 condition in the states north of California. In northern California 

 it becomes somewhat reduced, with leaves less than 2 cm. long, flowers 

 8 to 12 mm. long, and calyx teeth equal in length to the tube or 

 shorter. In Humboldt, Siskiyou, Trinity, and Lake counties it passes 

 into the variety congestus ; in the northern Sierra Nevada, into the 

 variety nevadensis (Distribution Map 9).

 (approaches var. nevadensis). 



Var. nevadensis Ottley n. comb. (pi. 80, figs. 9-16). Perennials 

 (flowering the first season), prostrate, with wiry branches; pubescence 

 always appressed; leaves 1 to 1.5 cm. long; peduncles shorter than 

 in the species ; flowers 4 to 7 mm. long ; calyx teeth typically not more 

 than half the length of the tube ; wings equaling or exceeding the keel 

 in length ; keel not beaked, the upper margin almost a straight line. 



Occurring sparingly in northern California but abundant in the 

 Transition of the Sierra Nevada, and of occasional occurrence in the 

 mountains of southern California. Also in Nevada. DLstribution 

 Map 9. May-Avigust. In southern California its place is largely 

 taken by Ij. davidsonii Greene and L. argophyllus Greene var. decorus. 

 In the San Jacinto Mountains it is scarcely distinguishable from L. 

 eriophorus Greene var. hcermannii. It appears in San Diego Coiuity, 

 though hardly in its typical condition.
