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.

By: Newcomb, Lawrence and Illustrated by Morrison, Gordon. 1977, Little, Brown and Company, ISBN:0-316-60442-9

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.

This is perhaps the best of many field guides covering this region. Featuring 446 excellent color photographs (located with the text) and mentioning as similar to those illustrated are another 800 or so species for a total coverage of over 1,200 species. The start of each family section includes line drawings of some of the species showing important features. The text includes the usual description, bloom season, range, habitat and additionally includes information such as medical uses and lore and how the species was named. This is the official field guide of the Tennessee Native Plant Society.
