Of conservation concern.

Deeringothamnus rugelii commonly associates with both Asimina pygmaea and A. reticulata, and overlaps in flowering time with both. No hybrids between the two genera had been observed until a recent discovery of a putative hybrid between D. rugelii and Asimina reticulata by Dr. E. Norman (pers. comm. 1994).
