Taxonomic revision of the Asplenium wrightii complex (Aspleniaceae) with reinstatement of A. alatulum and A. subcrenatum
The Asplenium wrightii complex is morphologically variable and difficult in species delimitation. Owing to lack of comprehensive sampling in phylogenetic studies, the taxonomy of this complex remains unresolved. Based on extensive field observations, specimen examination and our recent molecular data, the present study aims to clarify the identities of three species of Asplenium in this complex from Asia. Our study revealed that A. alatulum and A. subcrenatum, previously treated as synonyms of A. wrightii, should be reinstated. A taxonomic revision of the three species, including their type information, detailed descriptions, voucher specimens, distribution, ecology, as well as taxonomic notes, is carried out.
