Micranthes stellaris grows as a leaf rosette, which produces a generally leafless stem up to tall. The leaves are toothed and somewhat fleshy, ovate or obovate, and without an obvious petiole. They are typically long (varying from ), with a cuneate (wedge shaped) base. The flowers are borne in a loose panicle comprising 5–10 flowers; M. stellaris has a chromosome number of 2n = 28. Linnaeus noted the species' occurrence in the mountains of Spitsbergen, Lapland, Switzerland, Styria and Westmorland. The name M. stellaris subsp. prolifera is used for plants from the south eastern Alps which have few flowers but produce bulbils along the stems.

Micranthes stellaris has an Arctic–alpine distribution. Further south, it is found from the Sierra Nevada in southern Spain to the eastern Carpathians,

In the Arctic, M. stellaris may occur down to sea level. Within the British Isles, M. stellaris is abundant in North Wales, Northern England and Scotland, reaching the summit of Ben Nevis , but is only found locally in Ireland. In the Vosges, it occurs around 3600 feet (1097 m), but only rarely below in the Swiss Alps. In the Sierra Nevada of southern Spain, it lives at up to It is self compatible, but its flowers are protandrous, and are usually pollinated by flies.
