11. A. pycnosl achyus, Gray. Stout, 2 ft. high, more or less villous- 

 hoary: leaflets about 21, oblong, ^ in. long: fl. yellowish, in dense 

 cylindrical short-stalked spikes: pods crowded, retrorsely imbricate, ovate, 

 acute, laterally flattened, thin-coriaceous, glabrous, coarsely reticulate, 

 1-eelled. — In moist subsaline grassy land near the entrance to Eolinas 

 Bay, Bolander, 1863, Greene, 1888, also in a similar locality not so near 

 the se*a southwest of Mt. Tamalpais. 



5. GLYCYRRHIZA, Diosc. (Licokicb). Glandular-viscid perennials 

 with unequally pirmate leaves, and flowers in axillary peduncled spikes; 

 calyx 5-cleft. Stamens monadelphous or diadelphous; the alternate 

 anthers smaller. Pod short, compressed, prickly, indehiscent. 



1. G« g'lutinosa, Nutt. Two or three ft. high, erect or decumbent, 

 either nearly glabrous and viscid with minute sessile resinous dots, or 

 more decidedly glutinous by a villous or hirsute glandular pubescence, 

 never scurfy: leaflets 13 to 19, oblong-lanceolate, 1 or 2 in. long; stipules 

 ovate-acuminate to lanceolate, persistent: spikes merely oblong, 1 to 1% 

 in. long, on peduncles of 1 in. : pod bur-like. — Common in the Mt. Diablo 

 Eange, and on the plains eastward; also at Alameda. 



6. AMOBPHA, Linnseus. Shrubs with unequally pinnate leaves 

 which, with the young twigs and inflorescence, are pellucid glandular 

 and heavy-scented, the glands in age dark brown and opaque. Leaflets 

 many; stipules and stipels caducous. Flowers very small, dark purple, 

 in long and narrow terminal spikes. Calyx obconic-campanulate, 5- 

 toothed, persistent. Banner (the only petal present) erect, concave, un-

 glandular, scarcely dehiscent, 1- or 2-seeded. 



1. A. hispidnla, Greene. Two to four ft. high, pubescent or gla- 

 brous, the glandular dots supplemented on the twigs, stalklets and leaf- 

 rachis by acute prickle-like glands with tips more or less recurved: 

 leaflets 8 — 12 pairs, oval to linear-oblong, an inch long, retuse or emar-

7. PSEUD ACACIA, Tourn. (Locust-Teeb). Trees or shrubs with 

 odd-pinnate leaves and stout prickles in place of stipules, the leaflets 

 prickly-stipellate. Flowers showy, in pendulous racemes. Calyx slightly 

 bilabiate, 5-toothed. Banner large, roundish, reflexed, little longer 

 than the wings and keel. Stamens diadelphous. Pod linear, flat, 

 several-seeded, margined along the upper suture, readily dehiscent. 



1. P. vulgaris, Tourn. P. odorala, Moench. Robinia Pscudacacia.
