GILIA FAMILY 139 



3. P, douglasii Hook. Stems many from the root-crown, erect, forming a dense 

 tuft or rough mat 2 to 8 inches high and 3 to 12 inches broad, the branches of the 

 root-crown mostly short and erect, sometimes long aiid prostrate; herbage green 

 and lightly pubescent to gray pubescent, or the leaves merely ciliate below, the 

 upper portion glabrous or subglabrous ; leaves densely clothing the branchlets, 

 sometimes with similar leaves fascicled in the axils, the blades linear or subulate, 

 3 to 5 (or 8) lines long; flowers solitary in the upper axils, mostly sessile or subses- 

 sile ; calyx 4 to 5 lines long, the lanceolate or acerose teeth about I/2 as long as the 

 puberulent tube ; corolla white, whitish-lavendet or lilac, 7 to 11 lines long, its lobes 

 obovate, % to % length of tube; stamens unequal, included, the filaments shorter 

 than the anthers; style shorter than calyx. 



Rocky ledges or granite sand slopes, 4700 to 10,300 feet : northern Ventura Co. ; 

 Sierra Nevada from Tulare Co. to Modoc Co. and eastern Siskiyou Co. ; North Coast 

 Ranges from the Yollo Bolly Mts. to western Siskiyou Co. East to the Rocky Mts., 

 north to British Columbia. June-Sept. 



Tax. note. — Various collections from Oregon, Idaho, Washington and British Columbia, re- 

 ferred by American and European botanists to Phlox douglasii, agree with the original diagnosis 

 and the plate in Hooker, Flora Boreali- Americana (2:73, t. 158), save that in all collections 

 examined the calyx-teeth equal the calyx-tube or are slightly shorter or slightly longer ; whereas 

 in the illustration of the type (t. 158) the calyx-teeth are shown as Vn of the length of the calyx- 

 tube. No specimens have been seen which match the tj'pe in this particular, but the point is prob- 

 ably one of little more importance than is pubescence of the calyx, which in various northern 

 collections generally exhibits one of the following states: (1) calyx-tube villous or puberulent and 

 the teeth glabrous, (2) calyx-tube and teeth villous or puberulent, or (3) calyx glabrous or 

 nearly so.

Var. austromontana (Gov.) Jepson & Mason. Leaves loosely arranged (relatively remote), 

 usually long (8 to 12 lines) and comparatively broad (1 to 1% lines at base), the margins usually 

 not recurved or only slightly ; calyx-lobes strongly earinate-ribbed ; corolla white or bluish. — Mon- 

 tane slopes, 4500 to 7500 feet: San Gabriel Mts. (Blue Ridge, Peirson 3179) ; San Bernardino 

 Mts. (n. slope. Parish 3689) ; San Jacinto Mts. (Hemet Valley, Mum 5450) ; Santa Rosa Mts. 

 (sw. side, in upper Coyote Caiion, Jepson 1439) ; Cuyaniaca Mts. (betw. Cuyamaca reservoir and 

 Julian, C. V. Meyer 441; Talley's, South Cuyamaca, K. Brandegee). South to Lower California, 

 east to Arizona. The calyx is said to be plicate in the sinuses but this character in this group is 

 usually imaginary. 



Var. caespitosa Mason. Plants closely caespitose, a little moss-like, forming small but ex- 

 tremely dense cushions, the branchlets % to 1 inch high ; leaves densely imbricate, 1 to 3 lines long, 

 the margins revolute and thus making rib-like folds on the back which are usually more prominent 

 than the midrib and often obscure it. — Alpine summits, 10,600 to 12,500 feet: southern Sierra 

 Nevada (east side or easterly crests) from Olancha Mt., Tulare Co. (Hall tf- Bahcoch 5228) and 

 Piute Pass, Tulare Co. (Ferris 8883) to Parker Pass, Tuolumne Co. (A. L. Grant 1608), Mono 

 Pass (Jepson 4463) and Mt. Dana (Jepson 3293) ; White Mts. (Benton, near Foleys, ShocMey 

 116). East to the Rocky Mts., north to Washington. For California there is just cited only 

 collections representing the markedly condensed alpine form (Phlox muscoides Nutt.). 



Var. canescens Mason. Plants compact or cushion-like, 1 to 2 inches high and 2 to 5 inches 

 broad ; herbage villous- puberulent or slightly floccose-tomentulose ; leaves % to 3 lines long, as 

 if 3-ribbed beneath, the midrib prominent and rounded, and the margins revolute-rounded. — 

 Sandy ridges or rocky slopes, 4000 to 8000 feet: southern Sierra Nevada in Kern Co. (Pah Ute 

 Peak, Purpus 5341) ; Modoc Co. (Warner Valley, Manning 712; betw. Middle Lake and Lower 

 Lake, e. of Lake City, Manning). East to the Rocky Mts., north to Washington. The differentiae 

 relied on between var. canescens and var. caespitosa, as to the Californian representatives, are 

 extremely slight. Moreover they are not constant, so that var. canescens must be regarded as 

 a weak varietal unit.
