Penaga Laut is one of the coastal trees named in NParks’ Coney Island Beach Area A information. For a visit from Punggol, it offers an interesting change from identifying trees only by their overall size.
Its scientific name is Calophyllum inophyllum. Glossy oval leaves with many closely spaced lateral veins provide a useful feature to compare with an official reference.
Make this a look-and-sketch stop rather than a collecting activity. A careful observation can teach you more than taking home an unidentified leaf.

The NParks Penaga Laut record describes glossy oval leaves with dense, regularly spaced lateral veins visible on both surfaces.
Look at foliage that is naturally visible from the path. Do not bend or break a branch to improve the view.
Compare several clues. A glossy leaf alone is not enough, and a photograph taken in shade may hide the vein pattern.
NParks describes white flowers and round fruit that starts green and may turn brownish when ripe. These are additional features when present, not things every visit will reveal.
Leave fruit and flowers on the tree. Identification should not depend on picking, cutting or tasting plant material.
With children, ask which feature was easiest to notice and which was missing. That makes the difference between an observation and a guess easy to understand.
The official Coney Island beach guide includes Penaga Laut among Beach Area A’s plantings. Check the park map and current signs rather than assuming every tree nearby is the same species.
The botanical record also explains that its fruit can be dispersed by sea currents. This gives you a question to take home: how can a coastal plant reach another shore?
Discuss that process without placing fruit in the water to test it. The plant’s setting is part of the lesson, and it should remain undisturbed.
Our Coney Island beach-area guide helps place the stop within the island’s wider landscape. Choose the section that fits your group’s time and energy.
Draw an oval leaf and a few vein lines, then label the drawing as an observation or reference-based sketch. Keep those two sources of information distinct.
Check current park access and opening information before travelling. A useful visit can end with one tree feature you are more likely to recognise next time.
