| Oxytropis vassilczenkoi Jurtz. | |
| Publ. & Syn. | Jurtz., Bot. Mater. Gerb. Bot. Inst. Komarova Akad. Nauk SSSR 19: 262 (1959). Holotype (LE): Russian Far East: South Chukotka, "Anadyrskii raion, bas. r. Anadyr ...", 03. Aug. 1950, leg. S. Vallit. |
| Notes | Elven and Murray: Oxytropis vassilczenkoi was previously (and also more recently, Kozhevnikov 1980) considered one or more races of O. adamsiana. It replaces O. adamsiana east of the Kolyma River. Yurtsev: It is similar in general appearance to O. adamsiana but differs constantly in several characters of different parts of the plant. Elven and Murray: Two subspecies were proposed by Yurtsev. We do not find them very different and they are largely sympatric. Yurtsev: The species occurs in two eco-geographical races with ranges differing in details. Subspecies substepposa is perhaps closer than subsp. vassilczenkoi to O. uschakovii; some of the leaflets are sometimes subverticillate in O. uschakovii and O. vassilczenkoi subsp. substepposa, which might be explained by hybridization with xerophytic species of section Baicalia. |
