Plants 8-45 cm tall. Stolons filiform, densely crisped glandular villous, with scaly leaves. Stem glandular villous. Basal leaves with petiole 15-21 cm, glandular piliferous; leaf blade spotted, subcordate or reniform to orbicular, 1.5-7.5 cm long, 2-12 cm wide, 5-11-lobed, glandular hairy, base subtruncate or rounded to cordate, margin irregularly dentate, apex obtuse or acute. Cauline leaves and bracts 1-4, lanceolate, ca. 6 mm long, 2 mm wide. Inflorescence 7-61-flowered. Sepals spreading to reflexed, ovate, 1.5-3.5 × 1-1.8 mm, abaxially and marginally glandular hairy, 3-veined; veins confluent at apex. Petals 5, white, spotted, of which largest two lanceolate-oblong, 0.6-1.5 cm long, 2-4 mm wide, base clawed, apex acute, pinniveined; smallest three petals ovate, 2-4.4 mm long, 1.3-2 mm wide. Stamens 4-5.2 mm. Ovary ovoid, with a semiannular nectary disc; styles divergent.

Growing in forest, scrub, meadows, shaded rock crevices; 400-4500 m.

Flowering and fruiting from April to November.

Phylogenetic analysis of chloroplast sequence data derived from matK and rbcL was employed to examine relationships among sections of Saxifraga, the segregate genera Zahlbrucknera, Saxifragopsis, and Cascadia, and the relationships of these taxa to other Saxifragaceae sensu strict (Soltis et al., 1996). Results indicated that Saxifraga is polyphyletic, comprising two well-differentiated clades. One clade, Saxifraga sensu stricto, is the sister to the remainder of the family and consists of Saxifraga sections Irregulares, Heterisia, Trachyphyllum, Cymbalaria, Mesogyne, Xanthizoon, Porphyrion, Ciliatae, Cotylea, Ligulatae, Saxifraga, and Gymnopera. A second major clade of Saxifraga species, Micranthes sensu lato, comprises the large section Micranthes, as well as the segregate genus Cascadia, and S. tolmiei of section Merkianae.

The chromosomal number of Saxifraga stolonifera is 2n = 30 (Ma et al., 1990).
