Robust Rock Jasmine is a robust, runner carrying perennial herb, forming compact to loose mats. Flowers are 0.7-1 cm across, white with yellow eye. In older flowers the color changes to pink with a red eye. Petals are obovate to nearly round, 3-3.5 mm long, tip entire to wavy. Sepal-cup is 3-3.4 mm long 1/3 rd, to 1/2 divided, glandular-hairy; sepals triangular, bluntish, often tinged purplish. Ovary is spherical-depressed. Style is about 1.1 mm long, stigma nearly headlike. Flowering stems are stout, 4-9 cm long, glandular-hairy, 3-12-flowered, at length hairless. Bracts are 3.5-6.5 mm long, lanceshaped, blunt, glandular-hairy, tip sometimes purplish tinged. Flower-stalks are 2-6 mm long, slender, shorter and less often equalling the bracts. Stolons are chestnut brown, hairy and sparse glandulose, hairless at length. Lead rosettes are 0.4-1.4 cm broad, 1-1.5 cm apart or closer. Leaves are barely dimorphic, 4-9 x 1.5-2.8 mm, inverted-lanceshaped to lanceshaped, blunt, greyish-green, outermost leaves on drying brown or yellowish-brown. Hairs silky hairy to hairy, white or rusty in color; longer hairs 0.4-1.9 mm long, appressed and hairy towards the tip, shorter ones sparse and glandular-stipitate. Capsule protrudes out of sepal-cup, brownish-yellow, valves blunt. Robust Rock Jasmine is found in Afghanistan to Himalaya till Nepal, and S. Tibet, at altitudes of 3100-5100 m.
