Simpoh Air Dillenia/Wormia suffruticosa Shrubby Simpoh

Simpoh Air
Dillenia/Wormia suffruticosa

Shrubby Simpoh

Fellow blogger in the Philippines mentioned a plant they call Mickey Mouse. It is interesting that different regions call different plants by different names.

Everything about it is large.

It has large leaves, and large yellow flowers. The flowers open at 3 am and last only a day. They are pollinated by bees which collect its pollen (the flowers don't produce nectar or a scent) or by small beetles and flies that scramble over it. Almost every flower sets fruit.

Main features: Large shrub or small tree. Grows up to 5m.

Leaves: Large (35cm long) oval leaves that are cabbage-like with slightly toothed edges.

Flowers: Large yellow, five petals.

Fruits: Red, splits open into segments; seeds covered with red flesh.

Status in Singapore: Common, particularly on wasteland.
World distribution: Throughout West Malesia.

Classification: Family Dilleniaceae.
The unopened fruits are surrounded by thick red sepals. To distinguish them from flower buds, the fruits face upwards while flower buds face down. The ripe fruit splits open also at 3 am, into pinkish star-shaped segments to reveal seeds covered in red arils. The plant blooms from age 3-4 and can live for 50-100 years! Plants in the Simpoh family (Dilleniaceae) hiss when the trunk or a branch is cut (you have to put your ear to the cut to hear it). The sound comes from the air that is sucked into the cut vessels.

leafUses: The large leaves of the Simpoh Air were used to wrap food such as tempeh (fermented soyabean cakes), or formed into shallow cones to contain traditional "fast food" such as rojak.

The Simpoh Air sends out very deep tap roots to reach underground water sources. So much so that their presence suggests an underground water source, and some people use the plant as a guide to decide where to dig a well. The timber is not useful because it is twisted and very hard.

Traditional medicinal uses: Simpoh Air is used to staunch bleeding wounds, and the fruit pulp may be used to wash the hair (Brunei).
