Oreocarya suffruticosa

Oreocarya suffruticosa is a species of flowering plant in the family Boraginaceae, native to the west and central United States and to northern Mexico. It was first described by John Torrey in 1827 as Myosotis suffruticosa and transferred to Oreocarya by Edward Lee Greene in 1887. Varieties of Oreocarya suffruticosa have previously been placed within several species of Cryptantha, including Cryptantha cinerea, Cryptantha jamesii and Cryptantha pustulosa.

Taxonomy
Oreocarya suffruticosa was first described (as Myosotis suffruticosa) by John Torrey in 1827. It was transferred to the genus Oreocarya by Edward Lee Greene in 1889. Starting in the 1920s, a broad circumscription of the genus Cryptantha was adopted by many botanists, and taxa recognized as varieties of Oreocarya suffruticosa were placed in several species of Cryptantha and their subtaxa, including Cryptantha cinerea, Cryptantha jamesii and Cryptantha pustulosa. A molecular phylogenetic study in 2012 showed that when Cryptantha was broadly circumscribed, it was not monophyletic, and Oreocarya was resurrected (along with some other genera). Oreocarya suffruticosa was divided into five varieties.

Varieties
, Plants of the World Online accepted five varieties:
 * Oreocarya suffruticosa var. arenicola (L.C.Higgins & S.L.Welsh) R.B.Kelley – synonyms include Cryptantha cinerea var. arenicola
 * Oreocarya suffruticosa var. laxa (J.F.Macbr.) R.B.Kelley – synonyms include Cryptantha cinerea var. laxa and Cryptantha jamesii var. laxa
 * Oreocarya suffruticosa var. pustulosa (Rydb.) R.B.Kelley – synonyms include Cryptantha cinerea var. pustulosa, Cryptantha jamesii var. pustulosa and Cryptantha pustulosa
 * Oreocarya suffruticosa var. setosa (M.E.Jones) R.B.Kelley – synonyms include Cryptantha cinerea and four varieties of Cryptantha jamesii
 * Oreocarya suffruticosa var. suffruticosa – synonyms include Cryptantha cinerea var. jamesii and Cryptantha jamesii

Distribution
