C. coriacea Davis in Notes R.B.G. Edinb. 24:29, t. 4 (1962). Syn: C. radula Fischer var. minor Boiss., Fl. Or. 3:909 (1875)!
Shortly crispidulous-pubescent chasmophytic perennial. Stems ascending, 3-15 cm, densely leafy, furrowed, branched in a short, ± corymbose, many-flowered panicle. Cauline leaves thick, firm, ovate, obovate to orbicular, coarsely and simply dentate, narrowed into a short petiole or ± sessile, middle cauline leaves 8-23 x 5-26 mm, upper leaves obovate-oblong, entire, sessile, minute, bract-like. Flowers 1-3 on rigid branches. Ovary shortly obconical, 2 mm. Calyx lobes narrowly triangular, 2-4 mm, patent, with very short reflexed appendages. Corolla broadly infundibular-campanulate, 9-12x8-12 mm, divided to ½ into ovate-oblong lobes barbate inside, corolla tube glabrous within, pubescent-hispid outside, lilac-blue. Style exserted. Stigmas 3(-4). Capsule erect, broadly hemispherical, 4 mm. Seeds ellipsoid, 1 x 0.4 mm, brown, shiny. FI. 7-9. Limestone crevices, rocks, 1540-2600 m.

Endemic. Ir.-Tur. element. The species is closely allied to C. hedgei (Upper Euphrates) and to C. radula Fischer from N. Iraq and possibly from Daralaghez (Soviet Armenia). In the latter area there probably exists another still undescribed species, intermediate in floral characters between C. hedgei and C. radula (as suggested on the basis of limited and insufficient material). Fedorov (in FI. U RSS 24:248-249, 1957) has stressed the variability of this isolated population in Daralaghez in relation to habitat. According to him the typical C. radula grows in shady and moister places whereas the plants near to C. coriacea grow in dry, open places. We are not convinced that the differences, especially in floral characters, are due only to ecological conditions. The whole group shows relationships with the variable, chasmophytic perennial C. postii from S. & E. Anatolia, N. Iraq and W. Syria (Latakia). The observed differences in habit, indumentum and floral characters between the different populations within and between the species are presumably due to long isolation and allopatric differentiation.
