Two new species of Meiogyne (Annonaceae) are described from Malesia based on morphological evidence and the results of a recent molecular phylogenetic study: Meiogyne saundersii from Peninsular Malaysia, Sumatra, and Borneo, and Meiogyne stenophylla from New Guinea. Meiogyne saundersii is morphologically similar to M. cylindrocarpa but differs in its leaf apex (abruptly caudate vs. acute, rarely shortly acuminate) and inner petal corrugation (tentacular vs. weakly longitudinally grooved). Meiogyne stenophylla is unique in the genus in its extremely narrow leaves (< 2 cm wide) with an attenuate apex; it is also similar to M. cylindrocarpa but differs in its lanceolate (vs. broadly ovate) petals and weakly warty (vs. weakly longitudinally grooved) outgrowth on the adaxial surface of the inner petals. In addition, two new combinations are proposed, Meiogyne wilsonii and Monoon papuanum , based on the results of the most recent molecular phylogeny of Meiogyne and related genera.
