Description and Ethnobotany
| Growth Form | It is a shrub up to 3 m tall, or small tree up to 15 m tall. |
|---|---|
| Trunk | Bark thin, smooth, pale grey-tan. |
| Foliage | Its opposite, stalked leaves have leathery leaf blades that are lance- to egg-shaped, and 8–20 by 3–7.5 cm, with scarcely visible venation, and prolonged tips. |
| Flowers | Its flowering clusters are 1.5–2.5 cm long, and found at the twigs. Each shoot bears up to 10 flowers that are 3–4 mm wide, with four purplish-pink petals. |
| Fruit | Its roundish fruits are 10 mm-wide berries that ripen dark purple. |
| Others - Plant Morphology | Probably the native Memecylon species most threatened with extinction, currently known in Singapore from just 2 wild specimens growing within the Singapore Botanic Gardens' Rainforest. These specimens may have descended from the holotype specimen collected from the same area in 1907 by British botanist and former director of the Gardens, Henry Nicholas Ridley (1855-1956), based on which the species was first described to science. |
| Habitat | It grows in the understory of lowland rainforests. It occurs locally in Singapore Botanic Gardens (Rainforest). |
| Associated Fauna | Its flowers are insect-pollinated. Its fruits are eaten by birds. |
| Cultivation | Tolerant of partial shade and semi-montane temperatures. Propagate by seeds and tissue culture. |
| Etymology | Genus epithet 'Memecylon' derived from 'memaecylon' -- as used by ancient Greek philosophers Dioscorides and Pliny to describe the red fruits of Arbutus unedo (Oriental Strawberry Tree) -- alluding to the pink to reddish berries often produced by members of the 'Memecylon' genus. Species epithet 'cantleyi' named after Scotsman Nathaniel Cantley (d. 1888), the Kew-trained superintendent of the Singapore Botanic Gardens from 1880-1888. |
