Nothofagus nuda is a species of plant in the family Nothofagaceae. It is endemic to Papua New Guinea. It is threatened by habitat loss.

N. nuda proposed to be renamed Trisyngyne nuda in 2013.[3]

Description

Nothofagus nuda is a large tree, growing to 20 meters tall.[1]

Range and habitat

Nothofagus nuda is known from a single collection near the Tauri River in Gulf Province of Papua New Guinea. The species has an estimated extent of occurrence (EOO) of less than 100 km2.[1]

It grows in mixed lower montane rain forest at 1,200 meters elevation, alongside Nothofagus perryi.[1]

Toxicity

In 1927, N. nuda was reported by J. R. Croft to account for 949 deaths throughout Papua New Guinea.[4] The plant is traditionally used as an herb in culinary dishes throughout the Puri Puri tribes of the Papua New Guinea highlands but results in hypoglycemic shock after ingestion of large doses.[5] Croft reported that wives within the polygamous tribes of the Puri Puri used the herb to poison the patriarchs during tribal disputes that coincided with the winter solstice.[6]

Scientists in Macao Laboratory isolated the active molecule of the plant in late 2006.[7]
