PHACELIA FAMILY 



255 



Montane gravelly flats or slopes in granite sand, 4000 to 8300 feet : Sierra Ne- 

 vada on the west slope from Eldorado Co. to Tulare Co. May-July. 



Tax. note.— The specific name is for a former student at Berkeley, Docia Patchett, who 

 worked upon the Phaceliae of California in 191G. She was the first to note distinctions between 

 these plants and the plants of Phacelia humilis of the east slope of the Sierra Nevada.

15. P. marcescens Eastw. Stems erect, 

 simple or branching, 4 to 9 inches high ; herb- 

 age and inflorescence glandular, puberulent ; 

 leaf-blades ovate to ovate-lanceolate, com- 

 monly entire or some toothed at base or with 

 1 or 2 pairs of supplementary lobes; racemes 

 rather dense, the flowers subhorizontally 

 spreading ; corolla blue, deeply cup-shaped, 

 cleft half-way, 2 lines long, only gradually 

 or slowly pushed off by the enlarging cap- 

 sule ; scales long and very narrow, adnate or 

 sometimes with a short free apex ; stamens 

 exserted ; style cleft % or % ; capsule 1 

 (sometimes 2 to 4) -seeded. 



Montane flats or slopes, 4500 to 6900 feet : 

 Sierra Nevada in Nevada and Placer Cos. 

 June-July. 



Geog. note. — Phacelia marcescens is an endemic 

 of extremely narrow range. It has thus far been 

 found only on the headwaters of Bear Eiver and of 

 the North Fork American River. Its extreme longi- 

 tudinal range appears to be about ten miles. Here 

 cited are: Bear Valley, Nevada Co., Jepson 21,029; 

 Emigrant Gap, Jones 3294; Cisco Butte, Hall 8756; Serena Lake, near Conner Peak, Placer Co., 

 N. French 463. The original description reads, "stylo solum apice bifido," but material from the 

 type locality has styles cleft % of the way to the base.

 Bear Valley, Nevada Co., Bolander; Jepson, Man. 821 (1925). 



16. P. racemosa Bdg. Stem slender, erect, simple below, commonly with op- 

 posite branches above, 4 to 8 inches high, glabrous and glaucous below the inflores- 

 cence ; leaf-blades narrowly lanceolate, entire, tapering at base, puberulent, i/o to 

 l^^ inches long, shortly petioled or subsessile, equaling or surpassing the racemes ; 

 racemes loose, few to several-flowered, the rachises and calyx-lobes glandular- 

 puberulent; calyx-lobes linear-spatulate, unequal, shorter than the corolla, scarcely 

 accrescent; corolla dull white or blue, eylindric-campanulate, 1 to 2 lines long; 

 scales linear or oblong, wholly adnate ; stamens included, glabrous ; style cleft % ; 

 ovules 1 or 2 to each placenta ; capsule globose, shorter than the calyx. 



Stony soil of montane slopes, 5300 to 7500 feet : Sierra Nevada from Lassen 

 and Plumas Cos. to Fresno Co. June-July. 



Field note. — Phacelia racemosa, with its opposite leaves, has the habit of slender dwarf 

 Collinsias, the simple stem corjTiibosely branching at summit. The coroUa is pale, translucent 

 between the veins, thus imparting a coralline appearance. At base of corolla-tube inside occur 

 5 yellow glands or pits.
