Gonystylus bancanus grows as a tree to over 40 meters high. The trunk diameter reaches up to 120 centimeters. The brownish bark is scaly to flaky. Pneumatophores are formed in swampy areas .
The alternate, simple and long-stemmed, almost bare leaves are leathery and firm. The bald petiole is 8-18 inches long. The entire-margined leaves are elliptical, lanceolate to obovate, -eilanzettlich and 4–14 centimeters long and 2–7 centimeters wide. At the tip they are rounded or round-pointed to pointed, pointed. The nerve is pinnate with many side veins. The leaves are often slightly folded in.
The flowers appear in axillary and few-flowered, slightly hairy, short inflorescences. There are small and sloping bracts . The long-stemmed, small flowers are hermaphroditic with a double flower envelope . The flower stalk, up to 1.5 centimeters long, is finely haired. The outside hairy, leathery, about 5 millimeter large calyx is bristly and cup-shaped with 5 small triangular lobes. The small 13–20, almost free and narrow, awl, firm petals are bare and up to 3 millimeters long. There are about as many short stamens as there are petals. The bristly haired, round and multi-chambered ovary is upper constant upset with a long, wiry and thread-like, often slightly wavy style with capitate stigma .
Almost spherical, three-lobed and woody, loculicidal, brownish, somewhat rough, up to 4 centimeters in size, three-seeded capsule fruits are formed. The thick, reddish mesocarp is firm and fibrous.
