The tall dipterocarp tree in the middle of the photo above appears to be hosting two separate strangling figs. One of them at least and probably both are Ficus dubia.  When this photo was taken in December 2017 the Ficus dubia was sprouting new leaves.

The red circle and the red rectangle both relate to a known individual of Ficus dubia which fruits regularly attracting  hornbills and Large Green Pigeons.

The new leaves were accompanied by large green/pinkish stipules.

Some of the old leaves had yet to be replaced. The normal stipules of Ficus dubia are thin, with a sharp point and coloured red.

This close up of the trunk lower down shows  3 drop down aerial  roots of  Ficus dubia on the  RHS side of the host tree. On the LHS of the tree  there is a much thicker drop down root which is producing side roots that grip the trunk of the host. Most likely there are two individual Ficus dubia sharing this one host tree.
