Discussion

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).
