PHACELIA FAMILY 



251 



In Hanaupah Canon, near the "big spring," a plant of this species -was found in a crevice of 

 a cliff ; its stems hung do%vu so as to make a leafy drapery which covered six feet of the rocky wall. 

 The main unbranched stems were often 4 feet long. In material from this station teratological 

 flowers were found in which chorisis of the normally regular corolla was accompanied by a bilabi- 

 ate arrangement of the resulting petals. This station is at 4500 feet. The odor of the herbage is 

 rather mephitic and very disagreeable. The stems are very fragile. 



This species has been considered identical with Phacelia glechomaefolia Gray of Arizona 

 (Jones, Proc. Cal. Acad. ser. 2, 5:708). Phacelia glechomaefolia is, however, an erect loosely- 

 branched plant so different in form and leafage from P. perityloides Avith its low mound-like habit, 

 that the two, aside from the loose many-flowered ra- 

 cemes of the Arizona plant, contrasting with the close 

 few-flowered racemes of the Death Valley plant, may 

 be regarded as quite unlike.

6. P. hydrophylloides Torr. (Fig. 400.) 

 Stems few to many, spreading or decumbent, 

 usually branched, sometimes simple, finely 

 hispid with spi'eading hairs, 4 to 10 inches 

 high, arising subterraneously from the deep- 

 seated crown of a thick woody taproot ; leaf- 

 blades broadly ovate to oblong-ovate, incisely 

 few-toothed or lobed (especially towards the 

 base), silky-strigose on both sides, ^2 to 2i/2 

 inches long, sometimes with 1 or 2 pairs of 

 supplementary leaflets near summit of the 

 petiole; petioles 1 line to \y^ inches long; 

 racemes short, congested in a capitate cyme; 

 calyx-lobes narrow-linear or linear-spatulate; 

 corolla cup-shaped, violet-blue or whitish, 3 

 lines long, its spreading lobes revolute from 

 each side so that they become pointed, the 

 corolla-limb thus a little star-shaped; scales 

 semi-oval or broadly linear, wholly adnate, 

 the free edge undulate, the pair united below 



with base of filament ; stamens and style conspicuously exserted, the style 2-parted 

 nearly to the middle or below ; capsule 3 to 8-seeded, the seeds angled. 



Dry sandy or gravelly or granite soil, high montane, 5000 to 9000 feet : Sierra 

 Nevada from Lassen Peak to Tulare Co. East to Nevada. June-Aug. 



Biol. note. — In open pine forests of the Sierra Nevada Phacelia hydrophylloides forms cir- 

 cular colonies. The root-crown is very deep-seated; it gives rise to branched and spreading sub- 

 terranean stems which in the course of time develop taproots and become independent of the 

 central root-crown.

7. P. procera Gray. Stems very stout, erect, simple, usually in clusters from 

 a heavy root-crown, equablj' leafy to the inflorescence, 3 to 7 feet high ; herbage 

 puberulent, the summit of the stem and the inflorescence glandular; leaf-blades 

 ovate to ovate-lanceolate, 2^/2 to 41/2 inches long, laeiniate-pinnatifid into a few 

 coarse acute lobes, sometimes deeply incised, or the lower leaf-blades with supple- 

 mentary leaflets; racemes mostly geminate, the many pairs disposed in a compact 

 terminal panicle ; calyx-lobes linear, acute, shorter than the capsule ; corolla sordid
