Note: — Tectaria fuscipes is a common species in Guizhou, southwestern China and the type of Aspidium subsageniaceum was collected from Guizhou too. The diagnostic characters of T. fuscipes include stipe scales being blackish, fronds regularly bipinnatifid with its basal pinna deltoid (the basal basiscopic lobe or pinnules the longest), and veins free or those immediately beside costa non-stably connected. The type of A. subsageniaceum is exactly in agreement in morphology with T. fuscipes ; apart from the characteristic blackish scales and the produced lobes on basal basiscopic side of basal pinnae, even the occasionally connected costal veins can be seen in the isotype of A. subsageniaceum kept at the herbarium E. The type of A. subsageniaceum is clearly an individual of T. fuscipes . Notably, just before submitting this account, I noticed that in 1931 Christensen had already made correct identification of A. subsageniaceum and treated the name as a synonym of T. fuscipes ( Christensen 1931: 290) .
