PHACELIA FAMILT 261 



type loc. Red Mts., w. Stanislaus Co., Elmer 4338. P. cinerea Eastw., in Mcbr., Contrib. Gray 

 Herb. 49:26 (1917), type loc. San Nicolas Isl., Trask, is a synonym ace. P. A. Munz; an annual 

 plant might be described as a perennial and there would be little else to distinguish it from P. dis- 

 tans (E. F. Hoover). P. rainosissima var. cinerea Jepson, Man. 823 (1925). P. tanacetifolia var. 

 cinerea Brand, Univ. Cal. Publ. Bot. 4:216 (1912), type loc. Argus Eange, Inyo Co., Purpus 5042, 

 may belong here. 



24. P. vallis-mortae Voss. Steins erect, usually branching at or above the 

 base, set with scattered spreading bristles, 9 to 15 inches high ; leaf-blades glandular- 

 puberulent and appressed-hirsute, pinnately divided, 1 to 2 inches long, the divi- 

 sions remote, entire, incisely toothed or pinnatifid, % to 1 inch long ; racemes dense, 

 rather short ; calyx-lobes linear-oblanceolate, acute, puberulent and bristly; corolla 

 lavender, 3 to 5 lines long, its lobes rounded, over-lapping at base ; scales at base 

 eonnivent in pairs over base of filaments, retrocurved outward, then running 

 straight upward, adnate but with free lance-shaped or ovate tips ; stamens included 

 or a little exserted, glabrous ; ovary densely clothed with straight erect hairs. 



Brushy desert slopes or flats, 2100 to 7300 feet ; eastern Mohave Desert ; Inyo 

 Co. ; southern Mono Co. East to Utah. May-June. 



Tax. note. — In its narrow calyx-lobes, bristly inflorescence and often long pedicels this species 

 is allied to Phacelia cieutaria var. hispida ; in other respects it draws close to P. distans. Before 

 anthesis the calyx-lobes are already quite long and arch high, looselj' eonnivent by their tips above 

 the corolla-bud, thus leaving a free space between the summit of the corolla-bud and the summit 

 of the calyx (Ord Mt., Jepson 15,489). In Phacelia distans, before anthesis, the tips of the calyx- 

 lobes stand free and erect about the corolla-bud ; in anthesis the calyx-lobes are somewhat broad 

 and tend to half -conceal (sometimes they wholly conceal) the corolla-throat. In anthesis, the 

 narrow calyx-lobes of Phacelia vallis-mortae spread widely and cover little of the corolla throat. 



At the base of the filaments the pairs of corolla-scales in Phacelia vallis-mortae overlap. The 

 filaments thus appear set in a sort of open cup ; behind each filament is a round semi-transparent 

 area or spot in the tube of the corolla. The style is divided nearly to the base.

25. P. cieutaria Greene. Stem erect, branching, 1 to 2 feet high; herbage 

 puberulent and thinly spreading-bristly, somewhat glandular- viscid ; leaf -blades 

 2 to 5 inches long, pinnately divided into distinct segments or leaflets, or the larger 

 terminal segment merely pinnatifid or lobed ; leaflets Vl to 1 (or 214) inches long, 

 serrate or rather coarsely cleft-toothed, the lobes or teeth usually upwardly pointed, 

 or yet again the leaflets finely pinnatifid ; racemes rather dense, in 2s or 3s on the 

 ends of the branches, 1 to 4 inches long; calyx-lobes narrowly linear, thickly set 

 with horizontally spreading bristles ; corolla dingj'' white or pale lavender-white, 

 with translucent brownish spots in the throat, never blue ; scales adnate to corolla 

 on one side and to the stamen-filament on the other, the pair thus forming a deep 

 V-shaped pocket behind the filament, each scale with a very small acute free lobe 

 above the corolla attachment and a larger free lobe above the filament attachment, 

 this upper free margin often dentate; stamens included or only slightly exserted; 

 seeds % to I14 lines long.
