Notes: FNA7: "Draba novolympica is the same taxon that C. L. Hitchcock (1941) and R. C. Rollins (1993) called D. paysonii var. treleasei, and G. A. Mulligan (2002) called D. paysonii. The two are amply distinct and should be recognized as separate species. Draba novolympica is easily distinguished from D. paysonii by having fruit valves pubescent with 2-6-rayed (occasionally some simple) trichomes 0.05-0.4 mm, sepals 1.5-2.5 mm, petals 2-3.5(-4) × 1.5-2 mm, fruits (2.5-)3-4(-5) × 1.5-3.5 mm, styles 0.2-0.6(-0.8) mm, and ovules 1.2-1.8 × 0.8-1.1 mm. By contrast, D. paysonii has fruit valves pubescent with simple and 2-rayed (some 4- or 5-rayed) trichomes (0.2-)0.4-1 mm, sepals 2.8-3.5 mm, petals (4-)5-6 × (1.5-)2-3 mm, fruits (5-)6-9 × (3-)3.5-5 mm, styles (0.6-)0.8-1.2 mm, and ovules 1.7-2.2 × 1-1.4 mm.

Both R. C. Rollins (1993) and N. H. Holmgren (2005b) indicated that Draba novolympica (as D. paysonii var. treleasei) occurs in Alaska and Yukon, but we have not seen any material from there, and it is likely that their records were based on misidentified plants. Previous reports of D. paysonii from Canada (e.g., G. A. Mulligan 1971b) pertain instead to D. novolympica."
