Buah Keras Laut gives a Coney Island visit from Punggol a different kind of nature story: not just recognising a tree, but understanding why a coastal species was planted there.
NParks includes it in Beach Area C and describes leaves resembling water lilies. Its scientific name is Hernandia nymphaeifolia.
The important distinction is between a species’ former local absence and the trees reintroduced at a restoration site. Seeing a planted tree is interesting, but it does not by itself establish a self-sustaining wild population.

The NParks species record identifies Hernandia nymphaeifolia as Buah Keras Laut, also known as Sea-hearse.
The Coney Island beach guide compares its leaves with water lilies. Treat that comparison as a starting clue, not a complete botanical identification.
Use park interpretation and reference images together. A leaf-shaped resemblance alone can be misleading, especially when the tree is viewed from a distance.
The official beach guide describes the species as formerly locally extinct and identifies Coney Island as the first place where it was reintroduced into the natural environment.
‘Locally’ refers to Singapore in this context; it does not mean the species had disappeared from the entire world.
Reintroduction is also not the same as proving every later conservation outcome. The visitor information explains a restoration action, not a census of the species today.
NParks groups this tree with other coastal plantings in Beach Area C. That makes the stop useful for asking why parks may deliberately plant species visitors rarely recognise.
Ask a child: is a park only preserving what was already there, or can people help restore something missing? Discuss the idea without assuming every tree has the same history.
Our beach-area nature guide introduces the other themed areas without requiring you to visit them all in one outing.
Stay on permitted routes and look without taking plant material. A photograph of a sign and a rough leaf sketch can preserve the learning.
Do not treat unfamiliar plant names as food or medicinal advice. This guide is about a coastal restoration story and careful observation.
Check the current park information before travelling. Choose a visit that suits your group and leave room for the return journey to Punggol.
