Note — We have not seen the type of L. chrysoneurus in L, even Miquel himself had not seen it as he indicated when he made the combination, although the type should be in Leiden. However, there are some specimens from Java in L which match Korthals’ description of L. chrysoneurus well. Lasianthus glabrescens is conspecific with L. chrysoneurus . Lasianthus kurzii from mainland SE Asia, which has the same characteristics on leaves, stipules, bracts and flowers as

L. chrysoneurus , could not be separated from L. chrysoneurus ; it is also conspecific with the latter. Lasianthus chrysoneurus differs from L. obscurus by different indumentum.
