| Traditionally 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,... |

| Volume 3 represents a change in style for Flora Malesiana Series II, not just in the different coloured cover complete with illustration, but also in its stand-alone format. Each family, genus and species is described, and keys are provided for genera and species. For the two largest genera Microsorum (31 species) and Selliguea (49 species) regional keys to species are included in addition to the main key to species in Malesia. In total 228 species are described as follows: Polypodiaceae (183 species), Davalliaceae (31 species), Azollaceae (1 species), Cheiropleuriaceae (1 species), Equisetaceae (1 species), Matoniaceae (4 species) and Plagiogyriaceae (7 species). There is interesting discussion of regional variation within some of the more widespread... |

| A taxonomic revision of the fern genus Grammitis Swartz (Grammitidaceae) in New Guinea has been made, in which 64 species belonging to 14 species groups are recognised. Forty-five species are endemic to New Guinea and 21 species are hitherto undescribed. Problems in generic classification are outlined and the morphological characters used in the delimitation and description of the species and species groups are discussed. A bracket key to species and a multi-access key to species groups are provided for identification. For each species there is a complete citation of nomenclature, an illustration of a complete plant together with details of part of a frond, a full description and a summary of habitat, vegetation type and altitude. All of the specimens... |
