The Red-flowered Malayan Spindle Tree is a primary forest or freshwater swamp forest species that can grow up to 40 m tall. It is native to Singapore and classified as Vulnerable according to The Singapore Red Data Book (2nd Edition, 2008). It can be found naturally distributed in Northeast India, Myanmar, Thailand, Sumatra, Peninsular Malaysia, and Borneo.
The species has a dark green, heavy crown supported by wide-spreading limbs. Its bark is light brownish grey and lightly cracked and fissured. The leaves are large, oblong, thinly leathery, and have 10-14 pairs of side veins with very fine crowded parallel veinlets between them.
It produces small, faintly fragrant, red flowers measuring about 0.5 cm across in slender unbranched spikes. Its egg-shaped, olive-yellow coloured fruit is about 4 cm long and contains one brown seed covered in a bright orange aril. This aril is eaten by birds and small mammals like squirrels.
This Heritage tree had a girth of 3.1 m when it was endorsed in 2023.
