Revision as of 17:56, 18 September 2019
Stems usually hirsute basally, rarely glabrescent, trichomes often simple, sometimes branched. Basal leaves: blade surfaces sparsely to densely pubescent, trichomes simple and stalked. Fruits (3.5–)4–5.8(–6) cm; style (0.2–)0.5–1 mm, (rarely stout). 2n = 32.
Phenology: Flowering Mar–Jul.
Habitat: Bluffs, cliffs, ledges, rocky hillsides, open woods, bottom lands, gravel bars, meadows, streamsides, upland prairies, grassy swales, hillsides, stream bottoms
Elevation: 0-2500 m

Discussion
Some populations in northern Indiana and northern Illinois, [e.g., Herman 8790 (Jo Davies County) and Friesner 19072 (Elkhart County), both at GH] most likely represent hybrids between the two varieties of Arabis pycnocarpa. Trichomes borne proximally on stems of these plants are a mixture of forked and simple. It is expected that hybrids can be found where the ranges of the two taxa overlap.
