 leaves orbicular or nearly so, more or less cordate at base; cauline 

 leaves linear and acuminate-attenuate 1. C. rotundifoUa. 



1. Calyx lobes typically with 1 or more callose teeth on each side; mature capsule

1. Campanula rotundifolia L. Bluebell, harebell. 



Perennial to about 1 m. high, usually much smaller, the rootstocks slender 

 and elongate; stems erect or decumbent, scabrous, simple to freely branched; 

 leaves often in rosettelike clusters at or near base, long-petioled, round-cordate 

 to elliptic or oblanceolate, to 5 cm. long and wide, mostly toothed, early-wither- 

 ing; cauline leaves numerous, linear to narrowly lanceolate, smooth, to 1 dm. long 

 and 3 mm. wide; flowers as many as 15 in a lax raceme; calyx lobes narrowly 

 triangular to linear-subulate, usually entire, with sharp slender tips, erect to 

 spreading or reflexed in fruit, to 1 cm. long and 2 mm. wide; corolla violet-blue, 

 mostly 12-25 mm. long, the tube 7-15 mm. long; corolla lobes ovate-oblong, 

 abruptly pointed at tips, 5-8 mm. wide; filaments 2.5-4.5 mm. long, abruptly 

 dilated and ciliate on the basal portion; anthers 4-6 mm. long; capsule pendent, 

 obovoid to ellipsoid or subglobose, prominently ribbed, 4—8 mm. long, 2-4 mm. 

 in diameter. C. petiolata sensu Woot. & Standi. 



In wet meadows, edge of streams and rocky wooded areas in canyons of mts. 

 in the Tex. Trans-Pecos (Culberson Co.), N.M. (widespread in the mts.) and 

 Ariz. (Apache, Coconino, Greenlee and Graham cos.), June-Oct.; across the n.- 

 cen. portion of N.A., s. in the mts. to Tex., and n. Mex. 



Throughout its wide area of distribution this species is highly variable. 



2. Campanula Parryi Gray. 



Plant slender, to about 7 dm. high; basal leaves mostly oblanceolate to obovate, 

 to about 4 cm. long and 7 mm. wide, tapered at base; cauline leaves linear- 

 elliptic to linear-oblanceolate, to about 5 cm. long and 6 mm. wide, obtuse to 

 long-acute at apex; flowers rarely more than 3, usually solitary; calyx lobes lance- 

 subulate, to about 1.5 cm. long in anthesis, typically with 1 or more callose teeth 

 on each side; corolla bluish-purple, about 2 cm. long, divided to about the middle 

 into broadly ovate apiculate lobes; filaments broad and pubescent, about 2 mm. 

 long; anthers about 6 mm. long; style 1 cm. long; mature capsule erect, the 

 valves distinctly above the middle, usually two thirds to three fourths of the 

 distance from base to apex. 



In wet rnt. meadows in N.M. (rather widespread) and Ariz. (Apache and 

 Coconino cos.), July-Sept.; also Wyo. and Ut. 



3. Lobelia L. Lobelia 



Perennial, biennial or annual herbs; leaves mostly of a lanceolate type; flowers 

 axillary or chiefly in bracted racemes, usually inverted before anthesis, the pedicel 

 twisted; calyx 5-cleft, regular, parted to the summit of the ovary or the calyx 

 tube extending a little above the ovary; corolla variously colored, with relatively 

 narrow tube and spreading lobes, the tube usually cleft nearly to base between 

 the 2 lobes of the upper lip, the 3 lobes of the lower lip often somewhat united, 

 broad and conspicuous; stamens 5, usually free from the corolla; filaments free 

 at base, united distally into a tube; anthers united into a tube, the orifice of the 

 tube usually partly closed by the incurved tips of the 3 longer anthers, the shorter 

 anthers usually stiff-bearded at apex; corolla, stamens and style withering-persistent 

 on the fruit; capsule 2-celled, many-seeded, opening by apical loculicidal valves, 

 splitting at apex and the 2 halves recurved laterally.
