Draba longipes is a relatively common, white-flowered member of the mustard family (Brassicaceae) found in the mountains of Denali (primarily north of the Alaska Range crest). This species occurs in wet to well-drained alpine sites in gravel bars, meadows, scree slopes, rivulets and tundra. Plants are perennial herbs, loosely matted, with 10-15 cm tall stems arising from a branched caudex. Basal leaves are arranged in a loose rosette, lanceolate to oblanceolate in shape, up to 2.5 cm long, with entire or lightly toothed margin, and pubescent with branched and stellate hairs. Stems are unbranched, slightly pubescent often with a few small leaves or leafless. Flowers (3-15) are arranged in a terminal raceme. As with all mustards, there are 4 petals, 4 sepals, and 6 stamens. Petals are white to light yellow in color. Fruits are more or less hairless silicles, 5-11 mm long, 2-3 mm wide, the same length to half as long as the pedicels, linear-lanceolate in shape, flattened, and not twisted. This is one of the most common alpine species of Draba in Denali. Draba nivalis is another common, white-flowered Draba, but it has tiny leaves in dense basal rosettes. There are many other uncommon species of Draba in the park that can look similar, people wishing to make a more certain identification should consult a technical flora.

Draba longipes usually flowers in late June to early July with fruits mature by mid-July to late July.

D. longipes is monoecious with bisexual flowers. Flowers are self-fertilizing, with some outcrossing due to insect visits (Mulligan and Findlay 1970). Fruits are dehiscent and forcibly eject seeds. Seeds have no specialized dispersal adaptations.

D. longipes is an alpine species that grows in tundra, meadows, snowbeds, rocky slopes, cliffs, and scree. Soil pH for plots where D. longipes was found ranged from 4.6 to 7.4 with an average pH of 5.6.

Well-drained moist sites.
