Flowers solitary, 5-merous, perfect, borne on ebracteate pedicels, pedicels 3-5 mm long, tomentose. Epicalyx lobes 5, 1.5-2.2 x c. 0.3, linear to oblong-lanceolate, acute. Sepals 5, broadly deltoid, 2-2.2 x 1.2-1.6 mm, acute or acute-acuminate, apices glandular, surfaces glabrous adaxially, glabrous or sparsely tomentose abaxially. Petals 5, white to creamy 2.7-4 mm long, 2.5-3.2 mm wide, elliptical to spathulate, with rounded to emerginate apices. Stamens 10, filaments 0.5-0.8 mm long, anthers elliptical, c.0.5 x c.0.3 mm.

    Lectotype: Sikkim, Zemmu Valley, 4270 m, 13 July, 1909, Smith & Cave 1383a (CAL). (Dikshit & Panigraphi, J. Orissa Bot. Soc. 3(1): 31-36. 1981).

    We have not seen any specimen from Pakistan. Our observations are based on the material collected close to the border of Pakistan and Kashmir.

    Distribution: Afghanistan, Burma, Bhutan, Nepal and China (Xizang and Yunnan).

    On rocky or stony alpine slopes and meadows alt. 1300-1500 m.

    Sibbaldia perpusilloides can be distinguished from other species of Sibbaldia by its almost glabrous nature and its habit. It shares a moss or cushion-l ike habit with Sibbaldia tetrandra but Sibbaldia tetrandra is densely tomentose plant with mostly 4- merous flowers.
