LEGUMINOS^. 93 



umbel sessile: fl. smaller, the keel and wings white, the latter not 

 spreading. Along streamlets in the middle or higher Coast Range. 



16. L. Crassifolius (Benth.), Greene. Erect, stout, 23 ft. high, of 

 a dull green hue, as if glaucous, but minutely pubescent: leaflets 9 15, 

 thickish, obovate or oblong, obtuse, mucronulate, ^ in. long or more : 

 peduncles nearly equalling the leaves; umbel many-flowered, the 13- 

 foliolate bract a little below it; calyx-teeth triangular, short; corolla 

 purplish marked with green spots: pods thick, 2 in. long. Common in 

 the mountain districts. May, June. 



17. L. stipularis (Benth.), Greene. Not as tall as the last, more 

 slender, villous ivith spreading hairs and often somewhat glandular; 

 leaflets 15 21, obovate-oblong, acute, mucronate, ^ 1 in. long; stipules 

 large, ovate : peduncles short, 4 8-flowered, the leaf -like bract near the 

 middle, 3 9-foliolate: calyx 2 lines long, the subulate teeth short: 

 corolla purple; pod straight, 1 \% in. long. Contra Costa and Sonoma 

 counties. Seldom seen. 



18. L. balsamiferus (Kell.). Stoutish, erect, 2 ft. high, with 'the 

 foliage and inflorescence of L. crassifolius nearly; but herbage of a vivid 

 green, the stem and growing parts very glutinous from abundant gland- 

 ular-hispidulous short hairs. Hood's Peak, Sonoma Co., Bioletti. 

 Doubtless a rediscovery of Dr. Kellogg's Hosackia balsamifera. 



**## Stipules gland-like; leaflets few, unequally distributed; pods small, 



indehiscent, usually arcuate and long pointed. 



^Perennials (sometimes woody at base). 



19. L. glaber (Vogel.), Greene. Suffrutescent, 28 ft. high, erect or 

 decumbent, nearly glabrous; leaflets mostly 3, on young shoots 4 6, 

 oblong to linear-oblong, % % in. long, obtuse or acute: umbels many, 

 sessile; fl. 3 4 lines long, yellow, turning red: calyx-teeth subulate, erect, 

 rather less than half as long as the tube. Usually tufted and reedy- 

 looking, the foliage sparse, the flowers profuse. Common about San 

 Francisco, and southward throughout the State, in the Coast Eange 

 chiefly; flowering almost all the year round. 



20. L. Benthami, Greene. Eesembling the last, but smaller and 

 mostly prostrate: umbels on peduncles which equal or exceed the leaves 

 and are 1 3-foliolate-bracted at top: calyx-teeth more slender, stellate- 

 spreading in the bud and recurved in flower. Common on low hills near 

 the sea in San Mateo Co. June, July. 



21. L. jnnceus (Benth.), Greene. Nearly glabrous, erect, shrubby, 

 with slender branches reedy and sparsely leafy: leaflets obovate to 

 oblong, 2 4 lines long: fl. 3 lines; calyx 2 lines long or less; teeth very 

 short and blunt. A more southerly species than either of the two 

 preceding; but said to have been found near San Francisco.
