The material of this species available for study is very scanty. 
This circumstance probably accounts for the misinterpretation of its 
taxonomic position in the Genera Plantarum, again at t. 1180 of the 
present work, and once more in the Natiirlichen Pflanzenfamilien, 
which it is the object of the present description to adjust. The very 
characteristic hairs of the indumentum suggest a comparison of a 
species with Bor. oraginaceous rather than with Apocynaceous pl: 
and closer study of its salient characters aka it to be a Héiokaphaw
