Penarahan trees in Taman Tugu
Penarahan tree is an indigenous rainforest tree amongst the 4,100 trees added to the Taman Tugu site, selected in collaboration with Forest Research Institute of Malaysia (“FRIM”) and Malaysian Nature Society (“MNS”). This is one of the species being added which is considered as ‘Critically Endangered’ on the International Union for Conservation of Nature (“IUCN”) Red List of Threatened Species. This species is being threatened due to deforestation.
This tree is a large-sized tree that can grow 30m tall with a narrow, conical crown, and flaky bark. The leaves are alternately arranged and stalked leaves have leathery leaf blades that are lance-shaped. Its young leaf blades are covered with shaggy wool that drops off with age. The flowering cluster consists of up to 20 male flowers, while the female cluster consists of up to 10 female flowers. Both male and female flowers are densely covered with woolly hairs. Its fruits are egg-shaped and found in clusters of 1–3, with thick yellowish-brown wool. The seeds are bright red with fleshy covering.
The fairly durable wood is used to construct roof-supports or houses.
These trees grow in primary and degraded forests on the top of ridges, and hillsides, from lowland to 800m altitude. These trees are native to Malaysia, Singapore, Thailand, Sumatera, and Borneo.
