Uncertain ID. Sandy soil.
Flowers small for Astragalus that I know. Leaf shape and density about average ditto.
Leaves and calyx with long dense hairs, flower stem and leaf rachis less so. Calyx with very long narrow lobes. Flower wings relatively short for Astragalus.
Raceme densely flowered, pedicels short with narrow hairy bracts at base.
Observed on roadside in loose, sandy soil. Flowers were observed to be repeatedly pollinated by a Gray Hairstreak (Strymon melinus). Three other plants observed in viscinity flowering and fruiting.
Looks a little different than the Hood River Milkvetch
long wings, black hairs on calyx, erect banner, sparse small leaves slightly offset (alternate). early stage pod visible in photo 3. sandy soil.
