This species is sometimes placed in the Saxifraga genus, and sometimes in the Micranthes genus. Colorado flora expert, William Weber, places them in the Micranthes indicating that they have only basal leaves - whereas Sacrifraga have leafy stems. John Kartesz, another authority for plant names, also places these in the Micranthes genus.
The flower head of Snowball Saxifrage is a compact, slightly elongated cluster containing between 10 and 40 flowers, at the upper end of a stout, reddish stem, densely covered with yellowish, glandular, head-shaped hairs. Flowers have five ascending, green sepals below and between five white, clawed, oblong petals. Petals are a little longer than the sepals. The five stamens have green filaments and yellow anthers. It is found over a wide range of elevations but is most common in the high mountains, in the tundra zone above the treeline. Leaves grow only at the base; they are thick and fleshy, with coarsely toothed edges.
