Mystery of the seeds with wings (Part II)

Remember the picture of these seeds?

Today I took the same route home again. It was a sunny morning and I decided I should take a look at the tree(s) that disperse these seeds. I am totally clueless when it comes to identifying trees. Unless the tree is very commonly found along roadsides and I have learnt it in school.

Great morning at Pulau Subar Darat (Small Sister's Island)

My second consecutive morning shore trip.
Today we visited the other Sister's Island - Pulau Subar Darat (Small Sister's Island)

Welcome signage

The Sister's Island are not connected. Each of them has their own jetty to alight. Everyone got to work quickly after alighting. A team of 3 slide down the seawall next to the jetty to check out the rocky shore first. The second team, and I, started from the main lagoon. The lagoon at small sister's is different from big sister's. The proportion of sandy area in small sister's is larger than in big sister's.
