Kumlienia hystricula is is a small perennial herb growing from fleshy roots and a thick caudex. It produces a basal rosette of hairless green leaves which are rounded with several round lobes. Each leaf is one to three centimeters wide and is borne on a long petiole. From the patch emerge several inflorescences on erect to drooping peduncles up to about 20 centimeters tall. Each flower has 5 or 6 white sepals which look like petals. The actual petals are much smaller, shiny yellow-green structures curving around the center of the bloom. There are many stamens and pistils in the center. The fruits are bristly, lance-shaped bodies a few millimeters long and clustered together.
