(Orchidaceae: Malaxideae) with a new generic segregate: Blepharoglossum }, year = {2020}, keywords = {Blepharoglossum; Cestichis; Liparis; Malaxideae; Platystyliparis; Stichorkis}, doi = {}, url = {}, pmid = {}, journal = {Plant Systematics and Evolution}, volume = {}, number = {}, pages = {}, abstract = {Molecular studies have shown that Liparis s.l. is polyphyletic, with the epiphytic Liparis alliance well separated from the clade representing Liparis in its restricted sense and further forming a phylogenetically heterogeneous assemblage. The generic status of Cestichis, as the key member of the epiphytic Liparis alliance, remains contentious and the relationships between Cestichis, Stichorkis and Platystyliparis are still unclear and in need of further studies. We herein employ DNA sequence data from nuclear ITS and plastid matK regions to clarify the generic boundaries of Cestichis and its relationship to the allied genera. Results from both Bayesian inference and maximum-likelihood analysis congruently indicate that Cestichis as currently circumscribed is not monophyletic. The Blepharoglossum clade, corresponding to commonly recognized sect. Blepharoglossum, forms a monophyletic lineage closely related to the genus Oberonia instead of the core Cestichis clade. A re-evaluation of the diagnostic morphological characters reveal that this lineage represents a morphologically distinct group. Based on these results, Blepharoglossum is removed from Cestichis and elevated to generic status. Our study also sheds light on the homoplastic nature of some diagnostic morphological characters used traditionally in the taxonomy of the Malaxidinae.} }
