A taxonomic revision of Tectaria (Tectariaceae) from New Caledonia
2 July 2019Dong, Shi-Yong
A taxonomic revision of Tectaria from New Caledonia is presented here based on a thorough study of herbarium specimens from New Caledonia and adjacent Pacific islands. Six species of Tectaria are presently recognized in New Caledonia. Tectaria kouniensis and T. pseudosinuata are reduced to T. dissecta and T. sinuata, respectively. The morphological limit between T. seemannii and T. sinuata and the confusion of specimen citations in previous accounts are clarified. Apart from T. dissecta, the other five species, i.e., T. lifuensis, T. moorei, T. seemannii, T. sinuata, and T. vieillardii, are mainly distributed in New Caledonia, with only T. seemannii and T. sinuata recently reported also from Vanuatu. A key to species, typification of accepted names and relevant synonyms, and brief comments on relationships of species are provided.
