LEGUMINOS^. 21 



like bract near the middle, 3 9-foliolate : calyx 2 lines long, the subulate 

 teeth short: corolla purple: pod straight, 1 — Ifg in. long. — In the Mt. 

 Diablo Range, from Contra Costa Co. to Monterey. Seldom seen. It 

 probal)ly includes the IJoi^ackia tnacropliyJla and hahamifera, Kell. Proc. 

 Calif. Acad. ii. 123 & 125, but this may also be doubted ; and the species 

 ought to be carefully studied anew, in the field, by those who know 

 where to find any of the forms referred here.

 about Nevada City, and for a few miles westward and northward ; but 

 apparently of very limited distribution.

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

 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. and southward. June, July.

 glabrous, erect, shrubby, with slender branches reedy and sparsely leafy : 

 leaflets obovate to oblong, 2 ^ lines long : fl. 3 lines ; calyx 2 lines long
