The plant had not been documented in Missouri for nearly 50 years, yet it occurred in local abundance after the fires. It was soon touted as a pyrogenic resurrection, and, as happens with such botanical discoveries, there was much talk. Botanists and ecologists, myself included, ascertained that fire must have triggered dormant rootstock or seed into action that pre- scribed fire was giving this once exiled species a new lease on the land. It became another piece of “feel good” evidence that fire was restorative and the discovery went a long way toward affirming that belief. Desmodium humifusum is a procumbent trefoil derived from D.
