Physaria arctica is a perennial flowering herb in the family Brassicaceae, known by the common name arctic bladderpod. [1]
Plants are 6–12 cm high [2] with a short taproot and woody stem-base. Basal leaves, 2–6 cm and arranged in a rosette [3] predominate, and are obovate to oblanceolate, while cauline leaves, sessile or shortly petiolate, are oblanceolate or lingulate and 0.5-1.5 cm. [4] Inflorescences are loosely racemose, with flower stalks ascending or erect and 5–20 mm. There are 3-8 radially symmetrical flowers per inflorescence, [3] and the petals are spaulate, 5-6mm, with blades that narrow gradually to the claw. [4]
Physaria arctica grows in sand and gravel from calcareous bedrock, river bars and terraces, cliff ledges, scree and talus slopes. [4]
