 or pale blue; wings blue; keel ciliate for its whole length. 



Hillslopes near the seashore: San Francisco; Marin Co. 

 ■ 3. L. Chamissonis Eseh. Stems densely tomentose, woody 

 below, I to 3 ft. high; leaflets 6 to 9, more or less silky-pubescent, 

 oblong-oblanceolate; petioles short, mostly not as long as the leaflets; 

 flowers indistinctly or not at all whorled, bluish or lavender, the 

 banner with a permanent yellow spot; keel glabrous. 



Near the seashore: San Francisco and Marin Co. ilay. Very 

 doubtfully distinct from no. 2, which is only provisionally main- 

 tained. 



4. L. albifrons Benth. Branching bush 2 to 3 ft. high, with a 

 distinct woody trunk; growth of the season silky-pubescent; leaflets 

 7 to 10, oblanceolate to obovate, 10 lines long or less, silvery-silky 

 on both sides; petioles mostly longer than the leaflets; flowei-s deep 

 blue, in mostly distinct whorls in a loose raceme often 1 ft. long; 

 pedicels 3 lines long; upper calyx-lip broad, cleft, the lower entire; 

 petals subequal; banner broad, with a whitish or sometimes yellow 

 spot early changing to red-purple; keel ciliate; pod 2 in. long, 5 to 9- 

 seeded; seeds oval, 2 lines long, brownish, with a marginal dark line. 



Abundant, especially on the higher hills, in both the Coast Ranges 

 and Sierra Xevada. Feb. -May. Sometimes low and csespitose, 

 without a trunk. 



L. EMINESS Greene grows on ' ' burns ' ' on Mt. Tamalpais; the seed- 

 lings, germinating in the rich ashy soil, grow rapidly and crowd each 

 other up to a height of 6 ft. or less; the slender trunk, 1 in. in diani- 

 eter, being scarcely branched save at the top. TVe do not consider it 

 distinct from no. 4. 



L. juctrxDUS Greene. Shrub IJ to 3 ft. high, all the younger 

 stems silky-pubescent; leaflets 7 to 10, oblanceolate, obtuse, mostly 

 1 in. long; flowers blue, 6 or 7 lines long; raceme 6 in. long, the 

 bracts slender, a little shorter than the flower-buds; upper calyx-lip 

 deeply 2-cleft; lower lip entire or obscurely dentate; banner with a 

 vellow spot in center; keel obscurely or plainly ciliate just below the 

 apex.— Vacaville, Cal., £. S. Piatt, Mar. 23, 1898. This species
