Astragalus convallarius

When not flowering, Astragalus convallarius looks similar to Astragalus duchesnensis (which has purple flowers). You will see more branches than leaves on either plant. A. convallarius has smaller leaflets and much less distinct zig-zag stems. A. convallarius may look similar to A. linifolius but A. convallarius stems are not as robust, its pods are much longer, and the flowers have a yellowish tint without a keel spot. The stems of A. convallarius may also resemble some Brassicaceae or Polygoniaceae.

The stems of A. linifolius may also resemble some Brassicaceae or Polygoniaceae. Usually the pile of old stems at the base, and old pods, will be enough to tell them apart.
