Boechera microphylla (Nutt.) Dorn[FNA7, HC2]
little-leaf rockcress, small-leaved rockcress

Publication: Vasc. Pl. Wyoming ed. 3. 376. 2001.

Origin: Native

selected vouchers: WTU

Notes: FNA7: "Boechera microphylla is recognizable by its minute (0.05-0.1 mm), 4-8-rayed leaf trichomes, mat-forming habit, simple and 2-rayed trichomes on stems proximally, and ascending fruits. Both sexual and apomictic collections are known; further study is needed to determine whether they truly are conspecific. The taxa traditionally treated as Arabis (Boechera) microphylla vars. macounii and thompsonii are here recognized as B. macounii and B. cascadensis, respectively (see M. D. Windham and I. A. Al-Shehbaz 2007 for detailed comparison)."
