Similar to D. lamingtonii, but leaves covered on both surfaces with reflexed hairs and the corolla-lobes scarcely notched at all. In addition the calyx is divided almost to the base, whereas in D. lamingtonii it is only divided for a half of its length. South-western Iran. Fars Province, east of Shiraz behind the University library, on sunny or partially shaded limestone cliffs and also on gentle slopes, 1600-2250m. One of the most desirable species but difficult to cultivate. Should be kept somewhat drier than other species. Botrytis is especially troublesome during the autumn and winter. Clones in cultivation, JCA2936, SLIZE254, DZ I 00-41.
