Capnorea lasiantha Greene. Rootstocks stout; scapes 6-8 cm. long; 

 leaves spatulate to oblong, obtuse, sparsely strigose-pubescent, 2-4 cm. long, 

 the petioles mostly as long; corolla campanulate, the lobes shorter than the 

 tube. In moist soil, not rare. /rvss -~ /&~^-/ 



Capnorea villosula Greene. Rootstocks slender; scapes 5-6 cm. high, 

 shorter than the leaves; leaves few, spatulate, obtuse, pubescent beneath, 

 1-3 cm. long, the petiole as long or shorter; corolla rotate, about 1 cm. broad, 

 the lobes longer than the tube. Moist hillsides, near Pullman. x*-* -s^*"-''/

297. PHACELIA. 



Perennial or mostly annual herbs; leaves simple, lobed or 

 divided, alternate, or the lowest opposite; flowers in one-sided 

 raceme-like cymes; calyx deeply 5-parted, the lobes usually 

 narrow and similar ; corolla from almost rotate to narrow- funnel- 

 form, commonly with appendages inside of the tube, consisting 

 of 10 vertical plaits in pairs between the bases of the filaments; 

 stamens equally inserted low down or at the base of the corolla; 

 ovary with narrow parietal placentae; ovules and seeds 4- 

 numerous. 



Leaves pinnately cleft into narrow subequal lobes; flowers blue. 



P. 

 Leaves entire or with a few much smaller lateral divisions. 



Corolla bright blue, rather large; ovules 12-16. P. 



Corolla white or bluish, small; ovules 4. P. heterophylla. 



Phacelia idahoensis Henderson. Perennial, erect, 50-70 cm. high, nearly 

 glabrous below, villous-hirsute in the inflorescence, leafy to the top; leaves 

 pinnately-parted, the divisions again cleft ; inflorescence a dense narrow thyrsus, 

 with many short densely-flowered lateral branches; flowers pale blue; corolla 

 open campanulate, the lobes equalling the tube, which bears ten vertical 

 appendages within. In wet meadows, Craig Mountains and near Collins, 

 Idaho. 



Phacelia linearis (Pursh) Holzinger. Annual, 10-50 cm. high, simple 

 below the inflorescence; whole plant rough-hairy, usually with some shorter 

 white pubescence; leaves sessile, linear or lanceolate, entire or cleft into 2-5 

 narrow lobes; inflorescence usually branched, consisting of spike-like racemes; 

 pedicels short; calyx-lobes linear, hispid-ciliate; corolla violet-blue, nearly 

 rotate, 12-15 mm. broad, appendages 10, narrow, free from the filaments; 

 stamens equalling the corolla; filaments sparsely hairy; style 2-cleft; capsule 

 shorter than the calyx; ovules 12-16; seeds pitted-reticulate. Stony soil, 

 common in the warmer valleys. SZ'-KJ. 



Phacelia heterophylla Pursh. Biennial, erect, 50-150 cm. high, rough- 

 hairy and canescent throughout; leaves lanceolate, acute, simple or with 1 or 2 

 pairs of small lateral leaflets, the lower petioled, the upper nearly sessile; 

 inflorescence compound, of racemosely arranged spikes, much coiled when in 

 bud; calyx-lobes linear or lanceolate, very hispid; corolla white or whitish, 

 5-lobed, exceeding the calyx; appendages 10, broad, united at base to the 

 filaments; stamens much exserted, the filaments sparsely hairy; capsule ovate, 

 acute ; ovules 4 ; seed-coats pitted and honey-comb-like. Common and variable.
