Description
The species is 5 metres (16 ft) tall with either yellow or yellowish-brown colour. Leaf blade is elliptic and ovate with a diameter of 1.5–6 centimetres (0.59–2.36 in) by 1–5 centimetres (0.39–1.97 in). Female species have a subglobose inflorescence which is also oblong with a diameter of 1–2 centimetres (0.39–0.79 in) by 0.6–1.5 centimetres (0.24–0.59 in). It peduncle is 1–2 millimetres (0.039–0.079 in) long while its bracts can be as long as 5–9 millimetres (0.20–0.35 in). Flowers bloom from May to June while the fruits ripe from July to August.[2]
