Description: Shrub or small tree with at least youngest leaves bearing several hairs in axils of junction of midvein and largest pair of secondary veins on abaxial surface of blade, the hairs mostly caducous. Young twigs glabrous. Leaf blade 5.3-13.5 (-15.4) cm long, 1.6-3.9 (-6.4) cm wide. Petiole 10-29 (-44) mm long. Hypanthium 1.4-1.8 mm long. Fig. 18(B, E-H).

Habitat and Distribution: Jamaica: low-elevation hardwood forests on limestone in the John Crow Mountains; 150-760 m.

Taxonomy and Systematics: Mecranium axillare subsp. proctori is endemic to eastern Jamaica in the region of the John Crow Mountains. This taxon has essentially glabrous twigs, but with at least the youngest leaves bearing hairs on the abaxial surface at the junction of the midvein and two largest secondary veins. I have named this subspecies for George R. Proctor (b. 1920), who collected the type specimen.
