Cyananthus (Greek for blue flower). Campanulaceae. Ten or a dozen herbs, probably mostly perennial, of the high mts. of Cent, and E. Asia, with showy blue fls. terminating the ascending mostly simple hairy sts.: corolla funnelform, tubular or bell-shaped, 5-lobed; stamens free from the corolla, the ovate anthers more or less connate around the pistil: fr. a caps, with persistent calyx, loculicidally 3-5-valved: Lvs. alternate, usually small, entire or somewhat lobed. C. Iobatus, Wall., may be expected in collections of choice alpines: 4—5 in.: Lvs. small, narrowing to base, tooth-lobed at summit: fls. bright blue, 1 in. diam., resembling a shining periwinkle fl., funnelform with reflexed lobes, the corolla exceeding the calyx-tube and hairy in the throat. B.M. 6485. Other species mentioned in recent horticultural literature are C. microphyllus, Edgew. (C. linifolius, Wall.), with slender wiry sts., small entire lvs., and fls. like those of C. lobalus but with very hairy throat and longer narrower segms.; C. incanus, Hook. f. & Thoms., with numerous wiry sts., small nearly sessile lvs., and yellow campanulate fls. with hairy calyx; the W. China form of this (var. leiocalyx) has a less hairy calyx: C. Hookeri, Clarke, is an annual with small stalked lvs. and blue fls., from China and India; has rigid sts. with short lateral fl.-branches. L.H.B.
