Mountain kittentails is a perennial wildflower about 10 to 60 cm tall. The leaves are mostly basal, although several small, reduced leaves may be found below the infloresence. The basal leaves are long petiolate with cordate bases, and either somewhat round in shape to somewhat kidney-shaped. The leaf blades are palmately veined and about 2.5 to 8 cm long and about as wide. The leaf margins are shallowly to deeply toothed, with individual teeth often posessing even smaller teeth.
The infloresence is elongate, with individual flowers having four sepals and four unequal corolla lobes. The individual petals are from 4 to 7 mm in length. The stem is often somewhat villous within the infloresence. The seed capsules are about 5 to 7 mm high and perhaps slightly wider. They are shallowly notched. See the photo at right above.
