Pulse Family 219 



acute; umbels numerous, sessile; flowers 6-8 mm. long, yellow, 

 turning reddish; calyx 3-5 mm. long; the teeth subulate, erect, 

 slightly less than half as long as the tube. (H. glabra Torr.) 



Common throughout our range in dry places below 3000 feet. Flowering 

 nearly the year round. 



13. L. junceus (Benth.) Greene. Much resembling the last, 

 erect, shrubby ; leaflets obovate to oblong, 4-8 mm. long ; umbels 

 short-pedunculate to sessile; flowers 6 mm. long; calyx 4 mm. 

 long or less; teeth short and blunt. 



Said to occur along the seacoast of Los Angeles County, but we have been 

 unable to detect it. 



14. L.. leucophyllus Greene. Slender, 3-6 dm. high, much 

 branched and ascending, having the habit of L. glaber, but sil- 

 very canescent with a close short silky pubescence ; leaflets 3, 

 cuneate-oblong to linear, 12-15 mm. long; umbels few-flowered, 

 sessile or short-peduncled ; flowers 6 mm. long; calyx half as 

 long, with short slender teeth. (H. sericea Benth.) 



San Gabriel Mountains, Davidson. 



15. L. argophyllus (Gray) Greene. Densely silvery-silky 

 throughout; stems herbaceous, decumbent or ascending, 3-6 dm. 

 long ; leaflets 3-7, obovate and rounded, or oblong and acute, 5-12 

 mm. long; umbels dense, capitate, on short simple bracted ped- 

 uncles; flowers 8-10 mm. long; calyx half as long; the teeth 

 filiform, nearly as long as the tube, silky. 



In the pine belt of the San Gabriel and San Bernardino Mountains. 



16. L. Davidson! Greene. Suffrutescent at the very base, the 

 slender branches 3-6 dm. long, prostrate or decumbent, only 

 sparsely leafy, floriferous chiefly near the ends; herbage canes- 

 cent with an appressed silky pubescence ; leaflets 3-5,'cuneate- 

 obovate, obtuse or acutish, 4-8 mm. long; umbel unifoliate- 

 bracted, many-flowered, on a slender peduncle, 2.5 cm. long or 

 less, usually exceeding the leaves; calyx-tube 2 mm. long; the 

 teeth slender, 1 mm. long; corolla about 6 mm. long, sulphur- 

 yellow, becoming deep red in age; pod strongly arcuate. 



Wilson's Peak, where it was first collected by Davidson. This specie's 

 is very close to L. argophyllus and will no doubt prove to be only a form of it. 

 May-July. 



17. L. Nevadensis (Wats.) Greene. Branches mostly prostrate, 

 wiry at base and more or less woody, 3-6 dm. long; sparingly
