The following nomenclatural adjustments are proposed for the apomictic, hybrid species of Boechera to make the names available for the forthcoming account of the Brassicaceae in the Flora of North America. Two new species of Boechera (B. elkoensis and B. peirsonii) are described, and a new name (B. cascadensis) is proposed for the taxon currently known as Arabis microphylla var. thompsonii. In addition, 13 new combinations (B. calderi, B. californica, B. consanguinea, B. depauperata, B. drepanoloba, B. harrisonii, B. horizontalis, B. macounii, B. paddoensis, B. pauciflora, B. pinetorum, B. porphyrea, B. rubicundula) are validated. Notes on the delimitation and/or distribution of B. calderi, B. falcatoria, and B. goodrichii are presented. Boechera calderi is reported for the first time from California, Idaho, Montana, Oregon, Washington, and Wyoming, and B. goodrichii is reported for the first time from Nevada.
