4.1.7. Macropsychanthus dictyoneurus (Diels) L.P. Queiroz & Snak comb. nov.

Basionym: Dioclea dictyoneura Diels, Biblioth. Bot. 116: 97. 1937. Type: Colombia, Putumayo, La Concepción, Cuatrecasas 10836 (neotype, here designated: COL! [000054481]).

Note.

The holotype of Dioclea dictyoneura (Diels 929) came from Puyo, in Napo-Pastaza, in Ecuadorian Amazon. It was housed at B and was destroyed and we could not trace any duplicate. Maxwell (1969) cited four other specimens, from which we choose as the neotype the material from Concepción as it fits the protologue and was encountered ca. 280 km distant from the area where the original type was collected in the southern Colombian Amazon.
