Species which were named in honor of Heller include the Southern Pacific rattlesnake (Crotalus helleri), the Taita Thrush (Turdus helleri), and the Puna Thistletail (Schizoeaca helleri).
More than 20 endemic species of African violets (e.g. Saintpaulia teitensis) occur exclusively in that region and known endemic bird species are the Taita Thrush (Turdus helleri) and the Taita Apalis (Apalis fuscigularis).
The Taita Thrush was previously classified as subspecies of the Olive Thrush (Turdus olivaceus), but it is regarded as distinct species since 1985.
