A new species of the genus Ellipanthus Hook.f. is described from the Ankeniheny forest, a low- to mid-elevation humid forest in eastern Madagascar. It differs from the single species previously recognized on the island by leaf features, especially the size and shape of the blade and the shape of the apex. An illustration is provided for the new taxon, along with a preliminary assessment of its conservation status and a distribution map. An identification key is also included.
