sides, deeply cordate, 3-7-lobed to about the middle, the lobes triangular-

 numerous, in narrow compound racemes: pistillate flowers solitary, or rarely

 Along rivers and in waste places; from the eastern part of our range to the 

 Atlantic States.

1. Campanula uniflora L. Sp. PI. 163. 1753. Chiefly glabrous, 4-10 cm. 

 high, from a stout, several-headed rootstock: leaves small, 1-3 cm. long, 

 thickish, entire or nearly so; the lowest spatulate or oblong, obtuse; the upper- 

 most linear: flowers 8-12 mm. in length, mostly horizontal: calyx-tube nearly 

 as long as the lobes which are from half to fully as long as the deeply cam- 

 panulate bluish corolla: capsule cylindraceous or clavate, about 1 cm. long. 

 On bare alpine slopes in the Rocky Mountains, and extending into the arctic 

 regions. 



2. Campanula Parry! Gray, Syn. Fl. N. A. 2: 395. 1886. From elongated 

 and creeping filiform rootstocks, 8-25 cm. high, mainly smooth and glabrous; 

 stem slender, erect, simple and with slender-peduncled flower, or with some 

 lateral leafy branches: leaves thinnish, entire or sparingly callous-denticulate, 

 somewhat veiny; radical and lower spatulate or lanceolate with tapering base, 

 hirsute-ciliate; upper linear-lanceolate, from a sessile base, attenuate-acute: 

 flower erect in anthesis: corolla almost crateriform, 5-lobed to middle, spread- 

 ing, 2-3 cm. in diameter, violet-blue or even purplish, little surpassing the 

 linear-subulate often callous-denticulate calyx-lobes: ovary turbinate: capsule 

 nearly obovate, opening close under the base of the erect calyx-lobes. C. 

 planiflora. In the mountains of our range. 



3. Campanula rotundifolia L. Sp. PI. 163. 1753. Slender, branching, 

 10-30 cm. high, 1-10-flowered: root leaves round-cordate or ovate, mostly 

 toothed or crenate, long-petioled, early withering away; stem leaves numerous,

 sule nodding, opening at or near the base. (C. petiolata Rydb. Fl. Col. 326. 

 1906.) Subarctic and extending southward in the mountains to Mexico. 



4. Campanula aparinoides Pursh, Fl. 1: 150. 1816. Stem almost filiform, 

 3-6 dm. high, equably leafy to the top, the sharp angles rough with short re-
