Abstract:is described and illustrated based on the results of detailed morphological comparison and molecular phylogenetic analysis. Morphologically, Haplopteris mindanaoensis is characterised by having obovoid (rather than funnel-shaped) soral paraphyses and deep soral grooves with asymmetrical flaps. Analysis of a combined four gene (chlL, matK, ndhF, and trnL-F) plastid data set shows that: (1) the two included samples of Haplopteris mindanaoensis have the same distinct haplotype; (2) Haplopteris mindanaoensis diver… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
