General: perennial, the taproot topped by a branched or simple crown. Stems several or solitary, herbaceous, erect, simple, 5-30 cm tall. Flower cluster and herbage loosely and often rather thinly cobwebby-woolly-hairy.

Leaves: alternate, mostly 3-parted or pinnatifid with a narrow axis and segments, or in some stunted individuals sometimes all entire. Basal leaves tufted and persistent, 1-6 cm long, stem leaves often smaller but still generally well developed.

Flowers: numerous, stalkless in a terminal, dense, rounded or more often slightly elongated cluster with bracts at bases. Corolla persistent, white, the tube 5-9 mm long, quite a bit longer than the calyx, the 5 spreading lobes 2.5-5 mm long. Filaments attached at the recesses of the corolla, shorter than the 0.6-1.0 mm anthers. Style short, not reaching much, if at all, beyond the middle of the corolla tube. June-August.

Fruits: capsules with seeds 2.5-3 mm long, becoming slimy on the surface when wet.
