| Oxytropis middendorffii Trautv. | |
| Publ. & Syn. | Trautv., Phaenog. Pfl. Hochnord.: 49 (1847). Described from the Taimyr River in Taimyr (Siberia). |
| Notes | See Yurtsev's initial comments to sect. Gloeocephala and see Excluded taxa for Oxytropis middendorffii subsp. trautvetteri. Murray and Elven: We find the splitting of this species excessive, into six arctic and two near-arctic subspecies with comparatively narrow ranges: subsp. middendorffii from Taimyr to the Lena River, subsp. schmidtii in one locality just south of the preceding in southwestern Taimyr, subsp. orulganica in Kharaulakh, subsp. jarovii (non-arctic) between Kharaulakh and the Kolyma River, subsp. coerulescens mainly east of the Kolyma River in West Chukotka but also isolated in the Koryak Mountains, subsp. anadyrensis mainly in Chukotka but also with isolated occurrence much farther west, subsp. submiddendorffii disjunct in Wrangel Island and Chukotka, and subsp. trautvetteri (non-arctic) along the Okhotsk Sea. The proposed subspecies are entered but with strong doubts. Yurtsev: The species might be divided into three taxa ranked up to three species, each with 2-4 subspecies: one with middendorffii, orulganica, and submiddendorffii; one with coerulescens and jarovii; and one with schmidtii and trautvetteri. Additional studies are needed. Murray and Elven: Yes. |
