Notes

Distinguished from V. mearnsii by the distribution of hairs on its upper surface of the leaf, the narrower and deeper basal leaf sinus, the larger flowers, the entire sepals and the small rounded calycine appendages. V. merrilliana appears to be sympatric with V. rupicola on Mt Pulog but the latter species differs in its hairy petioles, completely hairy uppersides of the leaves, ciliate sepals and free or slightly adnate stipules.
