 Recognition

Dryopteris kinkiensis has an erect rhizome and 2-pinnate, ovate laminae, which are glabrous adaxially and scaly abaxially. The scales on the stipe are ovate, toothed and dark brown, and those on the abaxial costae inflated at their bases. The secondary pinnae are ± uniform in size for about half their length and then decrease to the apices, deeply toothed on the margins, and the basal basiscopic pinnae are not enlarged. The sori are arranged in one row either side of the costae, protected by reniform indusia (Zhang 2012; Wu et al. 2013).
