Discussion:

Type. In silvis secus originem fluminis Pacimoni, Amazonas, Venezuela, Feb 1854, R. Spruce s n (holotype K).

Standley describes the tomentum of the rachis and lateral axes of the inflorescence as “densissime adpresso-pilosula” which shows on the type specimen as a shorter, finer, more appressed pubescence, but on the Silva & Brazão 60839 specimen the tomentum on this portion of the inflorescence is densely hirtellous-tomentose with spreading rather than appressed pubescence.

In the original description the corolla is described from immature material, but is shown to reach a length of 35 mm in full anthesis in other specimens examined.
