AbstractTraditionally most species of Grammitidaceae have been placed in three genera, Ctenopteris, Grammitis and Xiphopteris, defined by frond dissection. Grammitis has simple fronds, usually with one row of sori on each side of the midrib. Xiphopteris has lobed to pinnate fronds, and one row of sori on each side of the midrib or rachis. Ctenopteris has fronds deeply lobed to tripinnate, with more than one row of sori on each side of the midrib or rachis. There are problems with the usage of these three names: Grammitis is now defined to include only those species with a dark sclerotic frond border, the type species of Xiphopteris has been transferred to Cochlidium, and the type species of Ctenopteris belongs to Prosaptia. In both the Old World and the New World, new genera have been or will be published to accommodate species from these three genera. The new genera relevant to Malesia are discussed.
