Astragalus missouriensis
(Missouri Milkvetch)
Family: Fabaceae (Pea)
Astragalus missouriensis grows on dry sites on the plains and foothills. Plants are sprawling with purple-pink flowers in clusters at the ends of stems. Fruits are plump, relatively straight and less than 1-inch long.

Compare to Astragalus shortianus, which grows in similar habitats. These two species are difficult to separate. Fruits of A. shortianus are curved and more than 1-inch long. Hairs of A. shortianus are attached at the base, while hairs of A. missouriensis are attached in the middle of the hair.  A microscope is usually needed to see this, and the experience is often ungratifying.
