Leaves imparipinnate or paripinnate; leaflets entire or rarely few-lobed on juveniles.

Inflorescences axillary, racemose, thyrsoid or spicate panicles. Flowers bisexual [or unisexual and then plants dioecious]. Sepals usually 3–5, usually much shorter than petals, hairy, free or fused. Petals 3–6, free or fused to staminal tube. Stamens 8–10, tube cylindrical, mostly slightly shorter than petals, margin entire, crenate, irregularly toothed or with appendages; anthers inserted within throat. Disc usually tubular with crenate margin. Ovary 2–5-locular, each with 1 or 2 ovules.

The timber of D. fraserianum and D. muelleri is easy to work and is often used for furniture and indoor fittings. The timber of D. rufum is similar to that of D. Muelleri but it has an unpleasant onion smell.
