I came across a Croton species which I had deduced to be Croton oblongus due to its narrower leaves when compared to that of Croton griffithii. If not, the two species looked rather similar.

Its male flowers were positioned at the top end of the flower stalk.

There were quite a number of these dried flowers at one part of the trail. But there were too many tall trees around making it difficult to determine the origin of the flowers. However, they looked like the flowers of Monocarpia marginalis.

This thin, rounded winged seed was found on the forest floor at several locations likely to be due to its wind dispersion mode. No idea what plant it belongs to. [Update: Aspidopterys concava - a woody lianas]

Some interesting sighting on the animal front: (1) A juvenile snake popping its head out from a bush of Piper lanatum. It sneaked away when I tried to get closer. (2) A swamp of hairy caterpillar, with orange head and light blue tail end, were taking cover underneath a leaf that looked like one from Pternandra echinata. (3) Another swamp of caterpillars that seemed to be able to weave silk around the leafless branches of their host plant. The leaf they were on was the last remaining leaf on the young plant.

A total of 5 new plants were seen and identified. Besides the three mentioned above, the other two were Gironniera parvifolia and Calamus melanochaetes.
