 Orange Co., Peirson; Palomar Mt., Jepson 1564; Moro Mils near Fallbrook, San Diego Co., 

 Abrams 3310; Warner Ranch, San Diego Co., Hall 9427 (a variant with long narrow leaves cor- 

 responding to var. barbarae in the bolanderi group, and, except for narrower stipules, probably 

 similar to the type of L. strictus Nutt.). 



Var. alefeldii Jepson comb. n. Stipules larger, sometimes nearly half as large as the leaflets; 

 flowers larger, 10 to 15 lines long, red, purple or blue. — San Gabriel Mts. to San Diego Co. 



Locs. — Claremont, Los Angeles Co., Chandler; Palomar Mt., Parish 4402; Fallbrook, San 

 Diego Co., Cleveland; Witch Creek, San Diego Co., Alderson. The segregation of this variety is 

 not always satisfactory since the larger-flowered forms do not always have larger stipules. It is 

 usually found with the species but is more common in San Diego Co. (Erythea 6:88). Feb.-June.

8. L. bolanderi "Wats. Hillside Pea. Stems angled, low and herbaceous, or 

 climbing 3 to 7 feet high on shrubs and woody below; herbage glabrous or finely 

 puberulent; leaflets narrowly elliptic to ovate, usually more acute at apex than 

 base, mucronulate, dark green, lighter below, % to 1% inches long; stipules broadly 

 or narrowly semi-sagittate; racemes many-flowered; lowest calyx-tooth lanceolate, 

 11^ to 2 times as long as the tube; corolla dull white, turning sordid in age, 7 to 9 

 lines long, the banner violet-veined, sometimes pink-tinged; seed with a small aril. 



Open or brushy slopes in the hills, 50 to 2500 feet : Santa Barbara Co. and the 

 Tehachapi Mts. to Humboldt Co. North to Oregon. Mar.-June.

The stipules are highly variable in size, shape and margin, and do not vary consistently with 

 any other character. Sometimes this species, especially near the coast, exhibits broad stipules 

 and glabrous or nearly glabrous herbage, sometimes broad stipules and pubescent herbage, some- 

 times narrow stipules and subglabrous herbage, in any case with either few or many-flowered 

 racemes, and so by many intergrades passing into the following rather indefinite variety. 



Var. violaceus Jepson comb. n. Herbage pubescent ; stipules narrow ; flowers sometimes 

 fewer. — Mendocino Co. to Los Angeles Co. : South Mill Creek, Ukiah, Jepson 9250 ; Mt. St.

 540; Monterey, Jepson 2995; Sycamore Canon, Santa Inez Mts., Jepson 9149 (stipules large). 



Var. quercetorum Jepson comb. n. Plants typically low, the stems erect ; pubescence whit- 

 ish; corolla tawny. — Inner South Coast Range from Contra Costa Co. to Santa Clara Co.: Mt. 

 Diablo, Brewer; Mt. Day, R. J. Smith; Mt. Hamilton, Greene. 



Var. tracyi Jepson comb. n. Stems erect, about 1^2 feet high ; herbage glabrous, the leaflets 

 beneath scantily puberulent; stipules rather narrow, the lower lobe curved; peduncles about 

 equaling the leaves; racemes 10 to 11-flowered, % to 1 inch long, the flowers crowded, 5 to 5^2 

 lines long; calyx-teeth not exceeding tube; corollas yellow or cream-color. — Brushy slopes, 3000 

 feet: Grouse Mt., Humboldt Co. 



Var. barbarae Jepson comb. n. Leaves narrowly linear to linear -lanceolate. — Monterey Co. 

 (Little Sur River, Davy 7379) and San Luis Obispo Co. (San Carpojoro, Gondii) to Santa Bar- 

 bara Co.
