Draba oligosperma Hook.[FNA7, HC, HC2]
few-seeded draba whitlow-grass

Publication: Fl. Bor.-Amer. 1: 51. 1830.

Origin: Native

selected vouchers: WTU

Notes: Rollins (1993): This species reproduces by agamospermy, which largely explains morphological variation among populations. Historically such variation received sub-specific ranking, but it seems best to leave the deviants undesignated taxonomically.

FNA7: "Draba oligosperma is a highly variable and widespread species that has been shown to be apomictic (G. A. Mulligan and J. N. Findlay 1970; Mulligan 1972). It has been divided into species and infraspecific taxa by previous authors; the variation is continuous in every character; there are no clear geographical and morphological patterns that support its division. For characteristics separating D. oligosperma from the closely related D. pectinipila, see 80. D. pectinipila.

Draba andina (Nuttall) A. Nelson (1899), not Philippi (1858) is an illegitimate name, sometimes found in synonymy under D. oligosperma."
