PHACELIA FAMILY 1 99 



veined with deeper blue or purple, lighter and often dotted 

 toward the center. — A foothill and valley species, reaching 

 Wawona and Yosemite Valley. 



3. N. humilis Eastw. Stems spreading, 2 to 8 in. long. 

 Leaves all opposite, Yz to \ x / 2 in. long, entire or with few 

 entire lobes, tapering to the base. Pedicels about as long as 

 the leaves. Corolla scarcely Y% in. across, white, often purple- 

 dotted but without a purple spot at tip of each lobe. — Hog 

 Ranch Road and Hazel Green to 8000 ft. alt., but not common. 



4. N. exilis Eastw. Stems slender and weak, 3 in. to 2 ft. 

 long. Leaves / 2 to 2 in. long, the lower deeply lobed, the 

 upper less lobed or entire, mostly petioled. Pedicels mostly 

 much longer than the leaves. Corolla Y% to Y% in. across, 

 white. — Our most common Nemophila, abundant in the Yo- 

 semite and throughout the lower part of the Yellow Pine Belt. 



N. sepulta Parish, may be found. It has pinnately lobed 

 leaves, the upper longer than the pedicels, and very small 

 white flowers (often bluish without). 



3. DRAPERIA. 



1. D. systyla Torr. Draperia. Stems V/ 2 ft. or less high, 

 from a spreading perennial base. Leaves all opposite, silky- 

 hairy, ovate, entire, 1 to 2 in. long, petioled. Flowers crowded 

 on the coiled branches of a naked peduncle. Corolla purplish, 

 about Yi in. long, funnelform. Stamens unequal, not exserted. 



We here adopt the generic name, Draperia, to also serve 

 as a common name for this plant, since no other has been pro- 

 posed. The genus was named in honor of Professor John 

 William Draper, of New York, a chemist and historian. 

 D. systyla is the only species, but it occurs in two forms. The 

 first is broad-leaved and grows plentifully on banks through- 

 out the Yellow Pine Belt of the Sierra Nevada. The second 

 (var. minor Brand) has leaves only % to Y> in. wide and more 

 wedge-shaped at the base. It has been collected in Yosemite 

 Valley. 



4. PHACELIA. 



Herbs with bluish or white flowers in coiled spikes or 

 racemes. Calyx 5-lobed nearly to the base. Style 2-cleft. 

 Capsule with 2 seed-bearing portions which nearly meet in the 

 middle. Seed-coats pitted or netted. The species are here 

 arranged according to habit, as a matter of convenience. It 

 is doubtful if the usual classification based on the number of seeds 

 is a natural one.
