Growing 5 to 38 centimeters tall with a slender taproot and mostly leafless stems, it has a delicate, glabrous appearance. Its broadly ovate to triangular leaves feature small, entire leaflets rarely exceeding 4 millimeters long, with petioles one to one and a half times the length of the leaf blade. The fruit is broadly oblong, 7.8 to 10 millimeters long, with narrow wings measuring 0.5 to 1.3 millimeters wide.
