Poikilospermum suaveolens is an epiphytic, dioecious, evergreen, stout and woody climber or scrambler.

The leaf blade is broadly ovate to ellipti­cal or obovate, measuring 10-40 cm x 6-25 cm and usually hairless. The leaf base is wedge-shaped to distinctly cordate and acute to obtuse at apex.

The flowers are in pseudo-umbel­lules. The male flower is sessile. There are (2-)4 tepals which are strongly incurved. There are (2-)4 stamens. The female flower is pedicel­late and with 4-lobed perianth. The stigma is with ligule.

The one-seeded fruit is entirely covered by the persistent perianth.
