Description
Trichostigma octandrum strongly resembles pigeonberry (Rivina humilis). These are shrubs or free-standing vines up to 10 m wide and 6 m tall, with hairless twining, trailing or climbing stems. The stems range from 4–15 cm in diameter. The leaves are entire 4–9 cm blades ovate on long petioles. The apex is short and glabrous.
