342 HYDROPHYLLACEAB. 



Higher hills of the Coast Ranges: Napa Valley; Bodega; Mt. Tamalpais; 

 Berkeley Hills and southward to Southern California. 



8. P. tanacetifolia Benth. Fiddle-neck. Stouter than P. distans, erect, 

 less frequently branching, the leaves similar but commonly less finely dissected; 

 racemes 3 or 4 in. long, ascending and approximate; sepals linear, beset with 

 rigid bristles, in fruit little exceeding the oval capsule; corolla open-campan- 

 ulate, 3 to 4 lines long, lavender-color or bluish; internal appendages entirely 

 adnate by the inner margins; stamens much exserted. 



Sacramento Valley and southward to Southern California. Apr. It fur- 

 nishes bee pasturage in about six weeks from seed and the bloom lasts about 

 six weeks. The nectar flows all day. The honey is amber in color, sometimes 

 light green and of a mild aromatic flavor. Cows fed on it show a marked 

 increase in yield of milk but will not eat it alone at first. Cultivated by bee- 

 men in southern Germany (Harry E. Home). 



9. P. malvaefolia Cham. Stinging Phacelia. About 1% ft. high, hispid- 

 bristly throughout, the bristles with a conspicuous pustulate base; leaves 

 simple, petiolate, round- or elliptic-ovate with broad and frequently truncate 

 or cordate base, slightly 5 to 9-lobed, toothed, 1 to 3 in. long; spikes solitary 

 or geminate; corolla white, longer than the unequal linear-spatulate sepals; 

 stamens exserted; capsule 2-seeded; seeds pitted. 



Oakland, San Francisco and Angel Island. 



10. P. rattanii Gray. Similar but the spikes more slender and elongated; 

 four sepals spatulate, the fifth obovate and longer; corolla only 2 lines long. 



Northern Sonoma Co. to Ukiah. June. 



11. P. californica Cham. Rock Phacelia. Erect, stout, 1% to 2 ft. high, 

 from a branched but depressed leafy woody caudex; stems and petioles with 

 scattered hispid hairs; the foliage strigose, either green or canescent; leaves 

 pinnate or pinnatifid, the large terminal lobe elliptic to lanceolate, with 1 to 

 several pairs of smaller or much reduced leaflets or lobes below, or entire; 

 petioles commonly long; spikes dense, ascending or erect, 1 to 2 in. long, mostly 

 rather short-peduncled, usually in a paniculate cluster at the end of the stem; 

 sepals oblong; corolla purple or white, 3 lines long; stamens exserted, long- 

 hairy at the middle. 



Very common throughout our district on rocky points and ledges, in typical 

 form on the San Francisco Peninsula and in Marin Co. May-June. Variable 

 in habit. Var. imbricata Jepson. Taller, often 2% ft. high; racemes 2 to 

 4 in. long, scattered in a looser panicle, less commonly in 2s and 3s and mostly 

 on longer peduncles; corolla dingy white; fruiting calyces ovate, conspicuously 

 imbricated. — St. Helena; foothills of the Vaca Mts. 



12. P. nemoralis Greene. Stems 1 or few, simple below, paniculately 

 branched above, 1V+ to 3 ft. high, very bristly with stinging hairs; herbage 

 light green; leaves elliptical to oblong, 1 to 4 in. long, simple and entire or 

 with a pair of small leaflets at base; radical and lower leaves on petioles 2 

 to 3 in. long, uppermost short-petioled or sessile; fully developed spikes 2 in. 

 long or more, slender, in twos or threes, terminating the stems or lateral 

 branches; corolla whitish, 2 lines long, the flower otherwise as in no. 11, to 

 which it is very closely related; capsule 2-seeded.

13. P. breweri Gray. Pour to 7 in. high, diffusely branching at the base, 

 the stems Blender and with rather long internodes; herbage harshly pubescent 

 witli rather Bhorl hairs; leaves oblong lanceolate, entire, cleft towards the base,
