Heliotropium derafontense is a good species; placed in synonomy by mistake under H. shoabense.

Recorded by Vierhapper from Jebel Derafonte. Description based largely on fruiting characters and the form of the calyx, corolla and stigma. Certainly, across Soqotra there is a great deal of variation between the four Soqotran species (H. riebeckii Schweinf. and Vierh., H. socotranum Vierh., H. shoabense Vierh. And H. derafontense Vierh.) and "morpho-types" in different areas can be distinguished by a mosaic of characters including flower colour, leaf shape, differences in indumentum and inflorescence structure. Unfortunately, the characters used by Vierhapper for distinguishing species (especially nutlet characters) are unreliable and do not correlate with geographically distributed "morph-types".
No material has been seen, so its status is uncertain. The type is apparently lost.
