Ourisia montana, Buch.

A small erect hispid plant, 1–2 ½ inches high. Stems creeping; leaves few, linear, ovate, or obovate, entire, 1–1 ¼ inch long, ⅓–½ inch broad. Petiole one-third as long as the leaf. Scape 1 ¼ inch, with one very small bract. Flowers solitary, large for the size of the plant, pedicels slender, springing from the base, and with the flower topping the leaves. Corolla large, white, oblique, limb 5-fid., ¾ inch diameter. Calyx 5-partite.

The large entire leaves, long pedicels, and large flowers, distinguish this species from Ourisia uniflora and Ourisia colensoi. Collected on Mount Alta Range, at 5,000 to 6,000 feet altitude.
