Style longer than the corolla ; corolla-lobes spreading. 



Corolla deep blue, twice as long as the calyx-lobes. C. prenanthoides. 



Corolla pale bluish, little longer than the calyx-lobes. C. scouleri. 

 Style included; corolla lobes erect. 



Herbage puberulent; leaves all entire. C. scabrella. 



Herbage glabrous; at least the basal leaves not entire. 

 Cauline leaves linear, entire; basal orbicular or cor- 

 date. C. rotundifolia. 

 Cauline leaves spatulate-lanceolate, dentate; basal 



similar. C. piperi. 



Campanula prenanthoides Durand. Pubescent or glabrous; stems usually 

 several, erect, 30-60 cm. high; leaves ovate-oblong to lanceolate, sharply and 

 coarsely serrate, acute, 1-2 cm. long, the cauline sessile, the lower ones short- 

 petioled; flowers in a raceme, short-pedicelled; calyx-lobes subulate; corolla 

 blue, narrowly campanulate, its lanceolate lobes 3 or 4 times as long as the 

 tube. 



In open places, southern Oregon, perhaps not reaching our limits. 



Campanula scouleri Hook. Glabrous or nearly so; stems slender, 20-30 

 cm. high, often with a few branches; leaves ovate to ovate-lanceolate or the 

 upper lanceolate, acuminate, serrate, tapering at base, the petiole margined; 

 flowers in a raceme or a few-branched panicle; calyx-lobes subulate; corolla 

 12-15 mm. long, pale bluish, somewhat funnelshaped, the lance-ovate oblong 

 lobes spreading, longer than the tube. 



In open woods, common. First collected by Scouler at Fort Vancouver, 

 Washington. 



Campanula scabrella Engelm. Ashy puberulent, tufted, the numerous 

 stems arising from a much branched base, 5-10 cm. high; leaves entire, firm, 

 spatulate to linear; corolla blue, campanulate, with lance-ovate lobes as long 

 as the tube. 



High alpine meadows, Mount Adams, and the mountains of northern Cali- 

 fornia, probably occurring in our limits. 



Campanula rotundifolia L. Glabrous, erect, branched at the very base, 

 10-40 cm. high; basal and lower leaves broadly ovate or orbicular, cordate, 

 dentate or entire, petioled; cauline linear, the lower somewhat spatulate, 

 acute, sessile, 2-7 cm. long; flowers solitary or racemose, erect; pedicels 

 slender, nodding in the fruit; calyx-lobes subulate, longer than the tube, one- 

 half or one-third as long as the corolla; corolla campanulate, blue, 12-20 mm. 

 long; capsule openings near the base. 



Prairies and rock cliffs from sea level to 2000 m. altitude. 



Campanula piperi Howell. Glabrous; stems densely tufted from a much 

 branched somewhat woody base, 4-10 cm. high, leafy; leaves thin, oblong- 

 lanceolate or spatulate, saliently dentate, acute, 1-3 cm. long, narrowed at 

 base into margined petioles; calyx-lobes subulate; corolla campanulate, 

 bright blue, 1.5 cm. long. 



Abundant in rock crevices in the Olympic Mountains at about 2000 m. 

 altitude. 



Family 100. COMPOSITAE. COMPOSITE FAMILY. 



Annual biennial or perennial herbs or undershrubs (in ours) ; 

 leaves without stipules; flowers in a close head on a common
