Original diagnosis/description

Petiolate leaves, abscised as a whole, regularly segmented, narrow and linear to lanceolate in gross outline, lacking an apical leaflet. Leaflets opposite to alternate and densely arranged, inserted laterally on the rachis at almost 90°, entirely free to the base, falcate to quadrate; apices bluntly rounded; bases slightly contracted. Several fine veins entering the leaflets, bifurcating close to the rachis and then traversing the leaflet perpendicular to the rachis. Margins and abaxial side of the rachis densely covered with long, stiff hairs; abaxial leaflet surface densely covered with soft, shaggy hairs.


From Latin villosus (shaggy, hairy).
