This curious fig growing in the greenhouse at Malesiana Tropicals, at Bau near Kuching is a liana.

The tesselated (tiled)  under surface of the leaf and the uneven leaf base indicates that this fig belongs to Section Kalosyce  (root climbers) but there are no known figs in Section Kalosyce with matching leaves.

Thanks to Tim Hatch and Peter Boyce for photos and information.
