 Description

Evergreen trees up to 40 m high. Stipules non-peltate. Leaves distichous, margin crenate; fimbrial vein complete; large, globular, glandular trichomes present on cuticle; solitary unicellular trichome type A absent; solitary unicellular trichomes type C present, with a large base equal to or greater than the diameter of the trichome and with a large, unicellular, thin-walled trichome emerging. Stomata randomly oriented; without thickened T-pieces of cuticle at the poles separating the two guard cells; without giant stomata over the major veins; stomata size within the areoles variable. Upper epidermal cells over veins not distinguishable from areolar cells, without granular cell walls. Male dichasium a solitary pseudanthium; perianth open and broadly campanulate, asymmetric and irregular; stamens usually >20, developing centrifugally; anthers often slightly curved; distal connective protrusion weakly developed, filament connective free, without epidermal papillae or with isomorphic rounded papillae. Female dichasium with 1 central dimerous flower and 2 lateral trimerous flowers, or 2 trimerous flowers; stigmas clavate and weakly decurrent. Cupule valves 4, with simple trichomes; with rows of stalked appendages, hairy with globular, glandular apices; nuts triquetrous or lenticular, 2- or 3-winged.

Pollen: Peritreme or goniotreme, mesocolpia straight to convex; colpi long, tenuimarginate, with V-shaped ends, margins not thickened, aperture >15.0 µm long, polar to equatorial length ratio 0.35–0.4.
