Boechera pendulocarpa (A. Nelson) Windham & Al-Shehbaz[FNA7, HC2]

Publication: Harvard Pap. Bot. 11: 77. 2006.

Origin: Native

selected vouchers: WTU

Notes: FNA7: "Though often treated as a variety of Arabis (Boechera) holboellii (e.g., R. C. Rollins 1993), B. pendulocarpa is easily distinguished from that species by having simple and 2-4-rayed (versus 4-8-rayed) trichomes proximally on stems, cauline leaves without auricles, fruiting pedicels gently (versus sharply) recurved, and shorter (2-)2.5-3.8 (versus 3.5-6.5) cm, non-secund fruits. The two taxa have allopatric distributions, with B. pendulocarpa found in the mountains of western North America and B. holboellii apparently confined to Greenland. Recent use of the name A. (Boechera) exilis for this taxon (e.g., G. A. Mulligan 1996; R. D. Dorn 2001; N. H. Holmgren 2005b) is based on misinterpretation of the type (M. D. Windham and I. A. Al-Shehbaz 2006)."]
