Uses — Colombia: fruits used medicinally for cold. Alkaloid slightly positive ( Schultes et al. 24393).

Notes — Guatteria ucayalina is well recognizable by a combination of a dense indument of brown, erect hairs on young twigs, lower side of leaves and pedicels, a mostly greyish upper leaf side, strongly recurved sepals, and long-stipitate monocarps. The leaf indument is variable from dense in most specimens to rather dense or sparse in mainly Venezuelan collections.

Guatteria ucayalina is widely distributed, ranging from Central America in the north (where it was previously known as G. recurvisepala ) to Bolivia in the south, and Venezuela and Guyana in the east.

The only specimen from the Atlantic coast of Colombia ( Forero 9699 from Chocó) is aberrant by monocarps with an apiculum of c. 1 mm long, whereas it otherwise never exceeds 0.5 mm in this species.
