0>'AGRACE,=E. 



Hillsides and ridges of the outer Coast Ranges: Santa Cruz; San 

 Francisco Peninsula; Oakland Hills; Belvedere; Mt. Tamalpai?; 

 Olema; Petaluma; Healdsburg, etc. June and July. Mostly 

 branched above, occasionally at base, often simple, especially when 

 low. Buds oblong, acute, puberulent. Anthers in anthesis coiling 

 into a ring. Less vigorous specimens, 2 to 3 in. high, are frequent. 



Var. concolor. Simple, 1 ft. high, nearly glabrous, leaves linear, 

 1 in. long; sepals pinkish, turned to one side in the flower; petals 6 

 to 6 lines long, crimson; anthers somewhat spirally twisting after 

 dehiscence; stigmas oblong or elliptical, \ line long; capsule unknown. 

 — Pope Valley grade from Calistoga, May 2, 1893; Walker Canon, 

 Vaca Mountains, May 17, 1892, Jepson. A puzzling form, referred 

 here provisionally as a variety. 



4. G. quadri vulnera Spach. Simple or with erect branches from 

 the base, finely pubescent or the younger parts (especially the ovary) 

 canescent; leaves linear or narrowly oblong, entire or slightly 

 denticulate, mostly less than 1 in. long, sessile or very short-petioled; 

 petals 4 to 6 lines long, truncate or obtuse or even subacute, towards 

 apex erose-denticulate; style longer or shorter than stamens; capsule 

 pilose-pubescent, 2-ribbed on the four sides, sessile. 



Very common in the Coast Ranges and Sierra Foothills. May- 

 June. A variable species, especially in pubescence, size, foliage, 

 color of flowers and character of capsules. The leaves subtending 

 capsules are often elongated, thickish and conduplicate, especially on 

 plants of the inner Coast Ranges; such plants commonly have very 

 lax spikes. Plants observed in 1896 at Forest Grove, Santa Cruz 

 Mountains, growing within a space of twenty square ft. and indubit- 

 ably of common parentage showed the following variations in color of 

 petals: (1) Pale lilac or almost white. (2) Similar in color but with 

 purplish or deeper colored base. (3) Similar to no. 1 but with small 

 wedge-shaped purple or crimson spot at apex. (4) Like preceding, 

 but with the spot larger. (5) Uniformly deep purple or crimson. 

 In these same plants the style was either shorter, as long as, or 3 or 4 

 times longer than the stamens. Capsule in this species also variable 

 as to ribbing; plants with only the anterior and posterior faces plainly 

 2-costate are referred to this aggregate. The var. tenella (G. tenella 

 as to Wats.) has nearly smooth capsules. The seeds of the species are 

 somewhat cubical, rather obtusely pointed at one end, with the 

 opposite end square and fimbriate-edged or margined. More exten- 

 sive comparisons may reveal several species here taken as one, but the 

 present results of field studies do not encourage this supposition. 



5. G. albescens Lindl. Stem simple or branching from the base, 

 1 to 2 ft. high; more or less canescent; leaves oblong to lanceolate, 

 sparingly denticulate, 1 in. long; flowers mostly crowded on many 

 short lateral spikelets; petals purplish blue, 3 to 5 lines long; capsule 

 oblong, conspicuously 8-ribbed, 3 to 6 lines long, pubescent. 



An indefinite and little known species: Oakdale (San Joaquin 

 Valley). Seemingly passes into the 



Var. micropetala (6. micropetala Greene). Leafy inflorescence
