21. P. ramosissima Dougl. Stems several from the woody root-crown, simple 

 or branching above, diffuse or trailing, puberulent and usually with a few short 

 scattered spreading bristles or rarely subglabrous, ll^ to 3Vi feet long; herbage 

 glandular (especially near the inflorescence) ; leaf -blades ovate to oblong in out- 

 line, hirsutulous, 1 to 3 (or S^/o) inches long, pinnately divided into 5 to 9 oblong 

 and serrate or incised divisions or leaflets, these 3 to 9 lines long, the lower distinct, 

 the upper more or less confluent; petioles i/4 to IV2 inches long; racemes borne in 

 clusters of 2 or 3, the clusters set on the branched forks of the peduncles, the forks 

 often divaricate; calyx-lobes obovate to oblong-spatulate or linear, often drawn 

 down to a narrow claw-like base, twice the length of the capsule or longer; corolla 

 sordid- or yellowish-white or bluish, campanulate, with rotate limb, 3 lines long; 

 scales elongated or narrow, enlarged downward into a semi-orbicular undulate 

 border ; stamens and style somewhat exserted ; seeds oblong, 1 line long. 



Brushy slopes or about rocks in the foothills or mountains or in gravelly stream- 

 beds, 20 to 9500 feet : transmontane Sierra Nevada from Siskiyou Co. to Inyo Co. ; 

 Sierra Nevada (w. slope) from Butte Co. to Kern Co.; Tehaehapi Mts.; Coast 

 Ranges from Lake Co. to Monterey Co. ; coastal Southern California from Santa 

 Barbara Co. to San Diego Co. North to Washington, east to Utah, south to Lower 

 California. Apr.-Aug. 



Geog. note. — The geographic range of Phacelia ramosissima longitudinally is marked, since 

 it extends from Washington south into Lower California and east into Utah, and is exceeded by 

 no other species of this genus save the complex-aggregate, Phacelia magellanica. Its altitudinal 

 range and its variety of physiographic situation is also considerable. It is found on the shore line 

 near Monterey at about 20 feet altitude, and inhabits the southern Sierra Nevada in the Kern 

 Caiion region on Soda Creek at 9500 feet altitude. It is also found in the caiions on the arid east 

 side of the Sierra Nevada in Inyo and Mono counties, on the plateaus of Lassen County and in 

 the canons of the inner foothills of the Mt. Hamilton Range near the San Joaquin valley floor. 

 By way of further contrast, it may be added that its habitats on the hUl slopes near Tomales Bay 

 in Marin County lie within twelve miles of Redwood (Sequoia sempervirens) colonies, and that in 

 upper Napa Valley near Calistoga it occurs within two miles of Redwood groves. This species 

 thus grows in a wide diversity of climatic and topographic areas. In so wide a geographic range 

 there is to be noted some variation in vegetative characters of the plant, especially in size and seg- 

 mentation of the leaf and in degree of pubescence and in glandulosity. These variations are only 

 partially associated with geographic distribution. 



All plants of Phacelia ramosis.sima throughout its range are glandular, or to some slight de- 

 gree glandular, on the stems, or at least near the inflorescence. In general, cismontane Sierra 

 Nevada plants tend to be less glandular than Coast Range plants. In the Coast Ranges the amount 

 of glandular pubescence in this species increases southward and is most marked in coastal South- 

 ern California, or somewhat marked in the region along the coast line from Monterey south. All 

 plants, in some degree, have the stems hispid or hirsute with spreading hairs, varying from near 

 subglabrous to rather densely bristly-hirsute; the stems are, in addition, commonly puberulent. 

 In aspect, in habit and in leaf character the species is most uniform on the west slope of the
