Description: Shrubs, treelets or medium-sized trees, evergreen or rarely deciduous (so far observed only in H. cerasoides). Young twigs glabrous or hairy.
Leaves petiolate; elliptic(-oblong), oblong or seldom obovate, base equal or rarely unequal, attenuate, wedge-shaped, obtuse or rarely (sub)cordate, apex usually obtuse, acute(-acuminate) or (caudate-)acuminate, rarely rounded or emarginate; upper surface of midrib (slightly) sunken, flat, or (both edges) slightly raised [with one or two groove(s) in the middle]; domatia of aggregated tuft of hairs present in some species, at the axils where secondary veins meet primary veins; tertiary venation reticulate.
Inflorescences usually on branches and axillary, one-flowered or seldom two-flowered, rarely cauliflorous and then > 3-flowered; pedicels often articulated above the base; bracts (and bracteoles) present or sometimes not seen (absent?). Flowers bisexual; sepals free or rarely basally connate, triangular to ovate; petals of the outer and inner whorls equal or slightly subequal, ovate, elliptic(-ovate) or (elliptic-)tongue-shaped, erect or spreading at anthesis; in dried condition often marked by yellow powdery material. Stamens generally ≥ 40 per flower, apex of anther connective flat-topped, covering the thecae. Carpels generally ≥ 10 per flower, cylindrical or occasionally flask-shaped, peripheral ones sometimes slightly incurved; stigmas ± globose, (ellipsoid-)obovoid, ellipsoid(-ovoid) or ellipsoid-cylindrical, generally ± hairy; ovaries hairy, 1 ovule per ovary, sub-basal. Torus (nearly) flat or (slightly) raised with flat-topped (or with rarely rounded) apex, generally ± hairy, often ± enlarged in fruit.
Monocarps per fruit few to many, red in vivo, stipitate or rarely (sub)sessile; seed-containing portion (sub)globose, ellipsoid(-cylindrical), cylindrical or rarely ± obovoid, apex sometimes (slightly) apiculate. Seed per monocarp 1, (sub)globose, ellipsoid, cylindrical or rarely ± obovoid; seed coat smooth; raphe flat or slightly raised; endosperm ruminations spiniform(-flattened peg).
Distribution and occurrence: World: 27 species, East Africa and Madagascar through southern and southeastern Asia to Malesia and the southwestern Pacific. Australia: 1 species.
The genus was originally erected and named as Hubera by Chaowasku (2012) to comprise species formerly included in Polyalthia. It was subsequently renamed as Huberantha because of a nomenclatural issue with the first name.
