In the northerly parts of California two slight and hazy variants emerge through the medium 

 of intergrades: Var. stkicta Brand. Stems slender, very strictly or rigidly erect, glandular- 

 pubescent (at least above), commonly non-glandular 

 below, frequently sub-glabrous or glabrous below, 

 mostly 8 to 11 inches high, simple or branched only at 

 summit, the cymes relatively loose; leaves narrowly 

 lanceolate, glabrous or subglabrous, at least below, 

 sometimes finely ciliolate or villous-ciliolate ; calyx 

 glandular-pubescent. — Montane valleys or fiats, 2300 

 to 5200 feet: eastern Tehama Co. (Battle Creek Mdw., 

 Mineral, Jepson 12,272) ; Siskiyou Co. (Edgewood, 

 Kisling) ; Humboldt Co. (Larrabee Valley, Tracy 

 8791, "flowering a month later than associated small 

 plants of the species" ; Corral Prairie, Trinity Summit, 

 Tracy 14,146). North to Washington. In no two 

 collections studied is the segregation of pubescence on 

 the various parts of the plant the same. 



Var. GLABELLA Brand. Habit of the species ; up- 

 per portions of stem and calyces glabrous, lower part 

 of stem pubescent but less glandular than in the spe- 

 cies; leaves as in the species, glabrous beneath; cymes 

 open. — Valley flats, 2000 to 2500 feet: Humboldt Co. 

 (Larrabee Valley, Tracy 8692 ) . North to Washington. 

 In the Sierra Nevada foothills is a form of more 

 significance because definitely restricted to a limited 

 area: Var. villosa Jepson & Hoover var. n. Simple, 

 erect, usually markedly villous, especially above ; co- 

 rolla purple or crimson throughout (both the lobes 

 and the tube). — (Caulis simplex, erectus, fere valde 

 villosus, praesertim supra ; flos per totam coroUam 

 purpureus vel puniceus. ) — Lower foothills from Placer 

 Co. to Calaveras Co.: Auburn, Bolander 4508; Pilot 

 Hill, Eldorado Co., Jepson 15,762 (type) ; Nashville, 

 Eldorado Co., Jepson 18.055; lone, Amador Co., Jep- 

 son 18,666 ; Mokelumne Hill, Blaisdell.

25. G. gilioides Greene. (Fig. 388.) Stem erect, loosely branching, leafy, 4 to 

 15 (or 23) inches high, or the few branches diffusely spreading, i/o to 2^4 feet long; 

 herbage more or less villous or pilose and glutinous ; leaves y^ to 1% (or 2%) inches 

 long, mostly petioled, the blades narrow-obovate to oblanceolate or linear, entire or 

 with a salient tooth on each side, or the blades pinnately cleft or pinnate with 3 to
