Discussion
Variety conjunctus is most easily recognized in bloom, the long, narrow flowers, with their cylindric calyces and, usually, lilac- or purple-tinged petals being diagnostic. When in fruit, it is easily confused with the narrow-fruited form of Astragalus reventiformis, a species of the inner slope of the Cascade Range in Washington.
