Entelea

Entelea arborescens or whau is a species of malvaceous tree endemic to New Zealand. E. arborescens is the only species in the genus Entelea. A shrub or small tree to 6 m with large lime-like leaves giving a tropical appearance, whau grows in low forest along the coast of the North Island and the northern tip of the South Island. The dry fruit capsules are very distinctly brown and covered with spines. The common name whau is a Māori word that appears to derive from the common Polynesian word for hibiscus, other malvaceous trees which whau superficially resembles. Alternate names include 'New Zealand mulberry', 'corkwood' and 'evergreen lime'.
