Scientific Name

Physaria acutifolia Rydb.

Description

Species Description - A small tufted perennial with a deep rather slender tap-root. Basal leaves numerous, 1.5-2.5 cm. long, oblanceolate or obovate, acute, entire or slightly wavy, very finely stellate: stem-leaves rather few, oblanceolate: flowering stems 4-6 cm. long, ascending or depressed: fruit small, obtuse or slightly cordate at the base, deeply divided above: cells inflated, almost spherical, 4-6 mm. in diameter: style about 5 mm. long.

Discussion

This species differs from P. didymocarpa in the smaller size, in the acute leaves, and the smaller fruit, which is more deeply divided above and less so below. In general habit it resembles more P. Geyeri, from which it differs in the turgid more spherical cells. It grows in the mountains, reaching an altitude of 3000 m.
