Ficus xylophylla at Mulu growing as a hemi-epiphyte on a host tree in floodplain forest next to the boardwalk that leads to the Deer Cave bat observatory. This fig was not fruiting at the time of our visit in December 2013 and was identified from the large, thick, leathery, oval leaves without a small drip tip and basal veins in the form of a V.
Note that the paired basal veins start close to the base of the midrib creating a V shape. If they started higher up the midrib in the shape of a Y this would indicate Ficus stupenda.
