freely branching habit, usually 10-20cm tall but sometimes more, the young stems reddish. Leaves evergreen, linear to linear-oblong with revolute margins, deep lustrous green and leathery, densely borne at the stem tips. Flowers fragrant, deep rose to white, 1.2-2cm long, 1-1.6cm wide, in terminal clusters of five to thirty, spring to early summer. Fruits not fleshy, often enclosed by withered flower. Czechoslovakia, in the Muran region of the Carpathians, in crevices on limestone and conglomerates at 700-1300m. Varies in the wild in leaf size, density and degree of revolution and in flower size. The following names have been given by Joseph Halda: D.a. subsp. arbuscula. This is more or less as described above but presumably has smaller flowers, because D.a. subsp. arbuscula forma grandiflora has flowers of the same size given in the main description. Other forms are albiflora (white), and platyclada (fasciated). D.a. subsp. septentrionalis has more elongated, yellowish-brown stems and shorter, more crowded, strongly revolute leaves. D.a. subsp. septrionalis forma radicans has slender creeping stems, some below ground which root freely, and smaller flowers. Forma platyclada 'B' and var. albiflora seem to be much the same as those of the same names under D.a. subsp. arbuscula.
