Negria is a plant genus in the family Gesneriaceae. Its only species is Negria rhabdothamnoides, commonly known as the pumpkin tree. It is related to Fieldia (syn. Lenbrassia) and Depanthus.[1]

Description

[edit]

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.

Distribution and habitat

[edit]

The species is endemic to Australia's subtropical Lord Howe Island in the Tasman Sea. 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]
