Description: Medium-sized tree, usually up to 25m tall under cultivation; Trunk- Up to 0.8m across, appearing more massive due to dense tangle of long dangling branchlets (up to 3m long) that emerge and cover lower trunk, especially in older trees. Bark greyish-brown, fissured; Foliage- Leaves smooth to slightly velvety with serrate and somewhat margins, simple, arranged spirally at ends of branches. Species is semi-deciduous, shedding its leaves around once to twice a year, usually in response to dry weather; Flowers-Complex nectarless structures, each consisting of 6 large and fleshy-waxy petals that are red to orange on the inside and yellow on the outside, a disk of numerous short and yellow ring-stamens (which produce fertile pollen) arranged around reduced styles and stamens, and a pink-white anemone-like structure of hood-stamens (which produce sterile pollen). Highly-fragrant, primarily pollinated by carpenter bees (Xylocopa spp.) and bats (which consume the anthers and stamens, besides the sterile pollen).  Fruits- Nuts large (20-24cm across), globose, with hard woody exocarp (shell), produced in clusters, taking some 18 months to attain maturity, and resembling rusty-brown cannonballs when ripe.
