Erect often coarse annual, 1-10 dm. high ; stems simple or branched from the base, less 

 commonly branched above. Leaves lanceolate to occasionally elliptic, entire, sessile, 5-10 cm. 

 long, glabrous to puberulent or glandular to scabrous ; flowers sessile in terminal and some- 

 times axillary heads ; bracts foliaceous, lanceolate-ovate ; calyx obconic, becoming chartaceous, 

 lobes lanceolate; corolla narrowly funnelform to subsalverform, tube 2-3 times the calyx, not 

 clearly differentiated from throat, appearing as though dilated upward, salmon-yellow to cream 

 or nearly white ; lobes lanceolate, rotately spreading ; stamens unequally inserted on throat or 

 lowermost on tube, unequal in length, anthers blue, those of longer stamens exserted ; stigma 

 included ; capsule obovoid ; seeds solitary in the locules. 



Higher mountains of southern California from San Diego County north through the Sierra Nevada and

 ing on the river Columbia, as far to the eastward as the valleys of the Rocky Mountains, but not beyond that 

 great dividing ridge." May-Aug.

Erect, decumbent or spreading annuals, 5-15 cm. high, stems much-branched, rarely simple, 

 herbage glandular-pilose to villous, viscid, clammy. Leaves from variously toothed to pin- 

 nately dissected, when simple or nearly simple, the blade orbicular ; opposite or alternate below, 

 alternate above, thin, often very diverse on an individual plant; flowers sessile, congested in 

 clusters at ends of branches and in axils of upper leaves ; calyx campanulate, lobes lanceolate- 

 attenuate ; corolla narrow-funnelform to subsalverform, 8-12 mm. long, pink to white, lobes 

 rotately spreading ; stamens inserted unequally on the throat, the lowermost on short filaments 

 near base of throat, the upper on long filaments, exserted, filaments very unequal ; stigma reaching 

 the lowermost stamens ; locules of capsules 2-3-seeded. 



From Vancouver Island, south on the west side of the Cascades through the Sierra Nevada to Kern County 

 and in the Coast Ranges to Monterey County, California. Type locality: "about Fort Vancouver, on the

Erect annuals, 3-10 cm. high, divaricately branched. Leaves petioled or subsessile, blade 

 elliptic, entire or coarsely 3-toothed or incised at summit, those of inflorescence usually entire, 

 glandular-villous, thick; flowers sessile to subsessile or short-pedicelled, congested in clusters 

 at ends of branches ; calyx about 10 mm. long, segments lanceolate to lance-acuminate, glandular- 

 villous to viscid, green to base, the replicate sinuses chartaceous to the base of the tube, but 

 not membranous, calyx-tube thus with alternate green and white longitudinal bands ; corolla 

 tubular-funnelform, tube relatively stout, purple, throat and base of lobes yellow, lobes pink to 

 purple ; stamens unequally inserted, the upper on the throat, the lower on the tube, filaments
