Discussion

Variety sericea is the common phase of Oxytropis deflexa south of the Arctic. The variety is highly variable, especially in size and aspect of flowers. Flowers of some of the variants appear not to open, as if they were cleistogamous. The Pan-Arctic Flora (http://panarcticflora.org/) treats var. sericea as O. deflexa subsp. retrorsa.
