Discussion

T. D. Pennington (1990) neither discussed nor listed Sideroxylon rufohirtum. In A. Cronquist’s (1945c) revision of Bumelia and in some floristic treatments (e.g., R. W. Long and O. Lakela 1971; R. P. Wunderlin 1998), S. rufohirtum (as S. rufotomentosa) was included within B. reticulata as a subspecies or variety.

We recognize Sideroxylon rufohirtum as a species, following recent treatments by R. K. Godfrey (1988) and B. J. Herring and W. S. Judd (1995), who differentiated it from S. reclinatum based on consistent differences in indument, habit, and habitat. It is characterized by its habit as a low shrub, reddish brown to brown indument, and comparatively short pedicels.
