Ficus sumatrana. Dimensions 6 cm long excluding petiole (leaf stalk) and 4.3 cm wide.A distinctive feature of Ficus sumatrana leaves shared with Ficus micocarpa leaves is that the basal veins (blue arrow) lie within the looped marginal veins (orange arrow) that run around the edge of the entire leaf. Note that the tertiary venation above and below the basal vein on the right hand side of the leaf is similar and does not differ between the two areas. Contrast this with the tertiary venation surrounding the basal veins of Ficus sundaica also growing at Danau Girang which differs above and below the basal veins.
