Abstract
Gynochthodes leonardii, a new taxon from vegetations on ultramafic substrates in the northern and central regions of Palawan province, Philippines is described and illustrated. It is superficially similar to G. bartlingii but is readily recognized by the induments on its vegetative and reproductive structures, sulcate and lenticeled branches, scarious and deciduous stipules, 3–9 capitula in an inflorescence, and shorter corolla tubes.
