39. P. congdonii Greene. Stem erect and simple or more often divergently 

 branched, 2i,'2 to 9 inches high, sparing!}' leafy, hirsutulous ; leaves basal or sub- 

 basal ; leaf -blades obovate or narrowly elliptic to oblong, % to 1 inch long, entire, 

 strigose, the lower loug-petioled, the upper nearly sessile; racemes soon a little 

 loose ; calj-x-lobes linear to narrowlj' spatulate, puberulent and also hirsute-ciliate ; 

 corolla light blue, campanulate, slightly puberulent outside, 3 to 3V2 lines long, 

 its scales adnate, very short and broad at base (where attached in pairs to the fila- 

 ment and thus forming a large pocket), abruptly reduced and narrow at apex; 

 stamens included, the filaments glabrous or with scattered very short hairs ; style 

 usually cleft %, glabrous or scantily hairy below ; capsule about 6-seeded. 



Sandy soil around bushes, 2000 to 5000 feet, infrequent : Sierra Nevada from 

 Mariposa Co. to Kern Co. Apr. -May. 



Note on relationship. — "In general aspect Phacelia congdonii simulates P. humilis to such 

 a degree that it has been regarded as a variety of that species. This plant of the chaparral belt 

 in the foothills of the southern Sierra Nevada, however, may well be distinguished from Phacelia 

 humilis, a species which has its development in the Canadian Zone on the east side of that mountain 

 range. Morphologically, P. congdonii appears to be closest to P. curvipes. It is most readily 

 separated from that species by its short straight fruiting pedicels, light blue corolla, very short 

 (if any) hairs on the filaments, and the different form of the corolla-scales." — E. P. Hoover. 



Discovered over four decades ago, Phacelia congdonii is still so little collected that much 

 remains to be done in determining its full status. The following stations indicate its range: 

 Buckeye, Mariposa Co. ; Big Sandy Valley, e. base of Black Mt., Fresno Co., Hoover 3466 ; Stony 

 Flat, near Cedarbrook, Fresno Co., Hoover 4360 ; Greenhorn Pass, Kern Co., Purpus 5698.

40. P. keckii M. & J. Stem diffusely branching from the base, reddish-brown, 

 5 to 16 inches high; herbage puberulent and thinly hirsute, slightly glandular; 

 leaf -blades oblong, mostly tapering at base, entire or with a pair of salient lobes 

 towards the base, % to 1% inches long, the petioles nearly as long or the upper ones 

 1 to 2 lines long ; racemes dense, terminal on the branches, 2 to 3 inches long ; calyx- 

 lobes oblong-oblanceolate, long-hirsute (especially on the margins) ; corolla violet 

 (the throat and tube white), turbinate-campanulate, 3^2 to 4 lines long, only 

 slightly exceeding the calyx, its limb 3 to 5 lines wide ; stamens glabrous, included. 



Dry ridges, 3500 to 5000 feet : Santa Ana Mts. June. 



Eef.— Phacelia keckii M. & J., Bull. Torr. Club 51:298 (1924), type loc. trail from Glen 

 Ivy to Santiago Peak, Santa Ana Mts., Mum 7056. The coroUa limb {Mum 4' J^eclc 7068) is 4 

 to 5 lines wide; in P. suaveolens, a near relative, 2 to 2% lines wide. 



41. P. saxicola Gray. Plant compactly branched from the base, 1 to 2 inches 

 high, the branches flowering from the base or below the middle ; herbage, inflores- 

 cence and calyces minutely giandular-puberulent and hispidulous with spreading 

 hairs ; leaf-blades obovate, entire, 1 to 2y-2 lines long, drawn down to a petiole i/^ 

 to as long; racemes only slightly seorpioid, the flowers discrete, the pedicels short, 

 subequal; calyx-lobes liuear-spatulate, nearly as long as the corolla-throat; corolla 

 purplish-limbed, tubular, % to 1^/4 lines long, the rounded lobes ascending, % line 

 long ; scales very narrow or none ; stamens % as long as corolla-tube and -throat, 

 the filaments a little dilated downward ; style short, cleft % ; capsule about half as 

 long as the fruiting calyx, about 50-seeded. 



Gravelly hillslopes, 6200 feet : southern Mono Co. East to southern Nevada and 

 northwestern Arizona. Apr. -July.
