Abstract

The taxonomic status of an unknown fern species from the Atherton Tableland, north-east Queensland, hitherto attributed to Asplenium L., was investigated. Phylogenetic analysis of trnL-F and rbcL chloroplast DNA sequences supported classification in Diplazium Sw., a finding supported by closer examination of scale features. Inspection of Diplazium type material determined that the Australian material belongs to Diplazium squamuligerum (Rosenst.) Parris, a species previously described from Papua New Guinea. A thorough description of this species and an amended key to the Diplazium species of Australia are provided. This study highlights the value of molecular study and close inspection of scale features for fern identification. Taxonomic revision in Diplazium is also discussed in light of the findings presented.
