This extremely rare, federal and state (Tennessee) endangered species is known from only three natural locations in Rutherford county Tennessee. The species was first recognized as a new species by biologist Milo Pyne (then Milo Gutherie) in 1988. Since then two other locations have been found. One, Flat Rock Cedar Glade, is now protected (see 'More Info' below). There were likely other locations early in the 1900s. It seems that the early Tennessee botanist Augustin Gattinger collected the plant in 1901 form a location near the La Vergne railroad station which is also in Rutherford county and a specimen was collected in 1948 from a location in Davidson county Tennessee which is now under Percy Priest Reservoir.

Similar Species: Tennessee Milkvetch, Astragalus tennesseensis has cream or yellowish flowers, yellow brown fruit and is hairy.

One of the best general guides to wildflowers of the North Eastern and North Central United States. Newcomb's key is an excellent, simple method for identifying plants. Newcomb has drawings for almost every plant mentioned that are excellent aids to identifying the species. Though only the more common plants are covered this is often the first book I pick up when trying to identify a wildflower.
