The leaves are radical, rather leathery, broadly spoon-shaped, scalloped, toothed, narrowed into the leaf-stalk. The bracts are linear. The flowers are white, in heads or cymes, densely-clustered. The sepals are united below, purplish, adnate to the base of the carpels, the calyx being half-inferior. The petals are not spotted, and are longer than the calyx. The beaks of the capsule are spreading. The plant is 3-6 in. high, flowering in July and August, and is a herbaceous perennial.

Starry Saxifrage (Saxifraga Stellaris, L.)

The habitat of this Saxifrage is alpine and subal-pine rills, damp rocks on mountains. The plant has the rosette habit, and the stems are tufted, but the aerial stems are scapes. The rootstock is branched and small. The plant is hairless, or has but few hairs. The leaves are rather succulent, fringed with hairs, entire, oblong, lance-shaped, wedge-shaped, toothed, narrow below, hardlv-stalked. The flowers are few, white, in a loose cyme or corymb. The scape bears no leaves. The sepals are lance-shaped. The petals are clawed, ovate, with two transverse yellow or purple spots below. The anthers and pistils are red.

The leaf-stalk is glandular, flattened, broad. The crenatures are cartilaginous. The flowers are white or pink, in a panicle-like raceme. The flower-stalks are glandular. The scape is without leaves. The sepals are reddish. The anther-stalks are swollen above. The anthers are red. The beaks of the capsule are spreading.
