Description

The pumpkin tree grows to about 8 m in height. It has pale, corky bark and soft, brittle wood. The ovate to broadly elliptic leaves are 70–200 mm long and 45–100 mm wide; they have glossy upper surfaces and are pale and sparsely haired beneath.[2] The flowers are large and orange with small red dots, appearing over summer from October to April. The fruit is a black, beaked capsule 15 mm long which holds numerous tiny, wind-dispersed seeds. The trees are found in the moist mountain forest of Lord Howe from about 500 m above sea level to the highest peaks at nearly 900 m.[3]

gollark: The SCP wiki does seem to favour bees over other insects.
