The species has a stout taproot that branches at the rootcrown and gives rise to several stems that are 20 to 150 centimeters (8 to 60 inches) tall.

The flowers have light- to deep pink petals 1 to 2 centimeters (0.4 to 0.8 inch) long.

The calyx (outer whorl of floral parts) ranges from uniformly finely stellate to bristly with a mixture of longer, simple to four-rayed, spreading hairs sometimes as long as 2.5 to 3 millimeters (0.1 to 0.12 inch).

procera by the presence of the hairs on the margins of the calyx lobes and by its large, somewhat fleshy, basal leaves, which are smooth to the touch on both surfaces.

Most of the historical records of this species are based upon occurrences in the Icicle and Peshastin Creek watersheds.
