21. L. leucophyllus Greene (pi. 76, figs. 1-8). Silky-canescent 

 perennials, with stems long and procumbent, bearing leaves with three 

 approximate leaflets; leaflets elliptical (oblanceolate), acute, variable 

 in width — 1 to 8 mm. ; umbels sessile or nearly so, consisting of but 

 1 to 3 (5) flowers 6 to 9 mm. long; calyx nearly one-half length of 

 flower, the narrowly linear teeth nearW one-half length of tube ; 

 claws of petals exserted ; wings longer than the keel ; legumes silk}''- 

 canescent, straight or falcate, slender, much exceeding the calyx ; 

 seeds 2 to several, rounded-oblong. 



Upper Sonoran and Transition from San Benito and Monterey 

 counties east to Inyo County, Distribution Map 7. April-July. 

 Apparently includes Greene's Hosackia procumhens. The calyx teeth 

 of the type of the latter are not so nearly triangular nor so different 

 in other ways from those of L. leucophyllus as one would be led to 

 think from reading Greene's diagnosis. Hosackia procumhens Greene 

 is midwa}^ between Hosackia sericea Benth. and the variety proposed 

 below.
