Galegeae is a tribe in the flowering plant family Fabaceae, subfamily Faboideae. The tribe is found mostly in the northern hemisphere, but can also be found in Australia, Africa, and South America. Recent molecular phylogenetic work has determined that tribe Galegeae is paraphyletic, and that its members are scattered throughout the IR-lacking clade.

Astragalus is a large genus of over 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of the Northern Hemisphere. Common names include milkvetch, locoweed and goat's-thorn. Some pale-flowered vetches are similar in appearance, but they are more vine-like than Astragalus.
