Identification tip: Similar to Tephrosia spicata, brown hair tephrosia, but may be distinguished by its flower stalk which is nodding while those of T. spicata are erect. Also, the foliage of Tephrosia onobrachoides is grayish green while T. spicata is rust colored due to a covering of brown hairs. Tephrosia virginiana has generally smaller leaflets and is the only species of Tephrosia which has erect simple stems and terminal inflorescences. It is also found on drier sites than most Tephrosias (Grelen and Hughes, 1984).
