Ficus sagittata photographed by Elliot Gardner  on 12 February 2020 at Bukit Raya in Kapit district central Sarawak. Collection #850.

Note that there is another  Ficus root climber   with much smaller leaves probably Ficus recurva Collection #849 also growing up the same tree trunk.

According to Berg (2011) in Flora of Thailand Pg. 579 the differences between F. villosa and F. sagittata are as follows;

  1. villosa: Lateral veins and smaller veins prominent beneath. Hairs on the lamina often (partly) patent (upright).
  2. sagittata: Lateral veins slightly prominent beneath, the smaller veins (almost) flush; hairs on the lamina (leaf) appressed (flat).

These photos were taken as part of a project entitled Ethnobotany and ethnotaxonomy of Moraceae in Sarawak supported by the National Parks Board of Singapore.

The photo above clearly shows soft long hairs which are predominantly laid flat against the rear surface of the leaf.  Compare the hairs shown above with  shorter, stiffer more upright hairs on the rear of a leaf of Ficus villosa.
