(klados, branch, and thamnos, bush, from the Greek). Ericaceae. Shrubs, rarely cult, for their handsome pink flowers Erect, with many virgate branches: leaves deciduous, alternate, entire: flowers pink, terminal, 1-3, nodding; corolla divided to the base or nearly so into 5 oblong petals; stamens 10: caps. 5-6-celled. - One or 2 species in Pacific N. Amer., from Alaska to Wash. Hardy, with handsome rather large pink flowers in summer; rarely cultivated They will probably grow best in peaty and sandy soil, in a half-shady position; prop, by seeds or by cuttings of soft wood under glass, and by layers.

C. pyrolaeflorus. Bong. Shrub, 4-10 ft.: leaves nearly sessile, obo-vate-lanceolate, mucronulate, glabrous, pale green, 1 1/2-2 1/2 in. long: flowers solitary, with 5 separate petals, 1 in. across. Alaska to Ore. G.F. 10:215. B.M. 8353. - C. campanulatua, Greene. According to Greene, this species differs from the preceding chiefly in the petals being united at the base and the anthers opening with a pore at the apex, and occurs in Wash., while C. pyrolaeflorus is restricted to Alaska, but the specimens from Ore. and Wash, do not differ from C. pryolaeflorus; possibly C. campanulatus was based only on an abnormal form.
