and Monterey to Marin Co. and Point Arena; northward ranging 

 towards the interior (Howell Mountain, Mt. Shasta), but only at 

 considerable altitudes. June. Peduncles sometimes as much as 

 22 in. high. 



2. P. strobilina H. & A. Erect, 2 or 3 ft. high, villous through- 

 out and glandular-pubescent on the branches, peduncles and peti- 

 oles; leaflets orbicular to rhombic-ovate, more glabrous above, 2 in. 

 long; stipules large, membranous, acuminate; peduncles shorter than 

 the leaves; spikes short-oblong, the bracts very large, deciduous; 

 calyx 6 lines long or more, the lower tooth much the longest and 

 equaling the purple corolla; stamens monadelphous; ovary pubescent. 



Hill country from Contra Costa Co. and Alameda Co. (Oakland 

 Hills, Torrey, 1865) to Santa Cruz (Bolander, 18G5). Seldom 

 collected. 



3. P. macrostachya DC. Nearly glabrous, villous-pubescent or 

 tomentose; stems erect, 4 or 5 or even 8 or 10 ft. high; leaflets ovate- 

 lanceolate, truncate to acute at base, lj to 3 in. long; peduncles very 

 much exceeding the leaves; spikes broadly cylindrical, silky-villous 

 with white hairs; bracts broad, acuminate, as long as the flowers; 

 calyx 3 to 5 lines long, the lower tooth a little the longest, exceeding 

 the purple petals; tenth stamen nearly free; pod hairy, ovate-oblong, 

 acute, flattened, 3 or 4 lines long. 



Along rivers and larger streams in the valleys, following the canon 

 bottoms in the mountains, and abounding in the salt marshes. The 

 most common and widely distributed species of the genus, occurring 

 both in the Coast Ranges and Sierra Foothills. The next is a very 

 closely allied form. 



4. P. Douglasii Greene. Habit of the preceding, but more 

 slender, nearly glabrous, the stem, and often the petioles, sprinkled 

 with elevated dot-like glands; leaflets rhombic-ovate, 1^ to 2h in. 

 long; racemes narrower than in the last, 2 to 3 in. long, on slender 

 peduncles 3 or 4 in. long; bracts deltoid and long-acuminate, cadu- 

 cous; rachis and calyx densely short-villous, the hairs often blackish, 

 the segments of the latter just shorter than the violet corolla. 



Apparently not common. Santa Clara Co. to Marin Co. Aug.- 

 Sept. 



5. P. physodes Dougl. Low, mostly but 1 ft. high, nearly gla- 

 brous; leaflets ovate, varying to orbicular, mostly acute, 1 to 2 in. long; 

 peduncles shorter than the leaves or exceeding them; racemes short, 

 dense, the bracts small; calyx cup-shaped, its teeth very short and 

 subequal, slightly villous with usually dark hairs, rather more than 

 £ as long as the corolla, at length much enlarged and inflated; corolla 

 5 to 6 lines long; petals greenish white, the keel purple-tipped; pod 

 roundish, compressed, 3 lines long. 



Common in open spots on bushy or wooded slopes of the higher 

 hills or mountains: Monterey; Gabilan Mountains; Mt. Diablo Range; 

 Wild-cat Canon; Marin Co. and northward. Apr.-June. 



6. P. Californica Wats. Low and tufted, the stems many from
