45. Scheuchzeri, VILL. (C. Linifolia, Willd.)

Perennial, 4-12 in.: stem 1-4-flowered, usually 1-flowered: root-leaves roundish, ovate, or cordate; stem - leaves linear or narrowly lanceolate, sessile, denticulate, the lowest stem - leaves spatulate: calyx-lobes slender, linear-awl-shaped, nearly as long as the bell-shaped dark blue corolla. Alpine and subarctic regions of Newfoundland, Labrador, Alaska, and Rocky Mts. to Colo., also in Eu. and N. Asia. F.S. 21:2205, not L.B.C. 5:485, which De-Candolle states is C. rotundifolia. variety alba, Hort. Flowers white. Gn. 60, p. 164. The stem - leaves of C. Scheuchzeri are distinctly serrate, while in C. rotundifolia they are entire; the flower-buds nod in the former, but are erect in the latter. The calyx-lobes are relatively longer in C. Scheuchzeri, and perhaps the bell is deeper.

46. Caespitdsa, Scop. (C. Pumila, Curt. C. Pusilla, Haenk.)

Perennial, 4-6 in.: root-leaves tufted, short-petioled, ovate, glandular-dentate, shining: calyx-lobes linear, erect, a third shorter than the bell-shaped corolla: flowers nodding, blue; pollen violet-colored. B.M. 512. Gn. 43:24; 48, p. 297; 60, p. 161. G. 25:307. R.H. 1908, p. 223. - Dwarfer than C. rotundifolia, with root-leaves never reniform, shorter-petioled, and lasting until after flowers have gone. Perennial, quickly forms a dense mat, and blooming from June till Oct. The European trade catalogues usually offer C. caespitosa and C. pusilla separately, and doubtless plants of distinct horticultural value are passing under these names, but there seem to be no sufficient botanical characters to distinguish them. Correvon says that C. pusilla differs from C. caespitosa only by its less stoloniferous character. variety alba, Hort., has white flowers G.C. Ill, 48:96. Gn. 72, p. 143; 75, p. 368. G.M. 54:466. variety pallida, Hort., has pale blue flowers G.M. 53:612.

47. excisa, Schleich. Perennial, glabrous, height 4-5 in.: stems slender, 1-flowered: root-leaves spatulate; upper leaves linear; calyx-lobes bristly, spreading, at length reflexed, a third shorter than the bell-shaped corolla: flowers pale blue, divided to about half their depth, with a round hole at the base of each sinus, which easily distinguishes it from C. pulla and all other campanulas. Rare in Alps. B.M. 7358. L.B.C. 6:561. Gn. 60, p. 64. - A rare rock-plant. Likes cool, moist air, and not too full exposure to sun.

bbbb. Flowers tubular, often long and narrow.

Campanumaea

(variant of Campanula). Cam-panulaceae. Twining or loose-growing perennial herbs, with rhizomes or tubers, rarely grown in. greenhouses. Leaves mostly opposite, simple and often cordate, petioled: flowers yellowish or greenish, broadly bell-shaped, . 4-6-lobed: fruit a berry. - Five species occur in the Himalayan and E. Asian region and the Malay Archipelago. C. javanica, Blume, and C. inflata, Clarke, both with yellowish brown-veined flowers are mentioned in gardening literature: the flowers are about l 1/4in.; in the former the calyx is nearly free from the berry, which is hemispherical; in the latter the calyx is adnate to the berry, which is ellipsoidal; both are twiners. C. gracilis, Hort., is of the genus Leptocodon, and C. lanceolata, Sieb. & Zucc, is a Codonopsis.
