Argyreia mollis  

The taxonomic concept followed here for A. mollis is narrower than the broad one adopted by Van Ooststroom. Notably, Argyreia obtecta has been resurrected as a distinct species. The plants from continental Asian show more diversity than the Malesian populations and it is not clear if this can all be accommodated in a single, albeit variable species. The characters useful for recognizing A. mollis at a glance are: upper surface of leaf glabrous; blades tending to be broadest at or below the middle; veins (in dry state) prominent on upper side; underside shining silvery sericeous; sepals oblong to oblong-elliptic, the backs of all sepals entirely covered with hairs (e.g. no glabrous margins).
