Fronds are tripinnate with oval to triangular pinnules. Fertile pinnae concentrate proximally on the frond, while vegetative pinnae mainly occur distally, but occasionally position proximally as the first ultimate pinna of the penultimate fertile pinnae. Fertile pinnules are strongly involute and enclose the reproductive organs. Fertile organs comprise six to ten sporangia grouped in a sorus with a receptacle. Individual sporangia are stalked and have a proximal horizontal biseriate annulus. In situ spores are trilete, triangular to circular, with baculate sculptures. Anatomically, the foliar trace is rake-like, with up to eight median xylary ridges composed of mixed metaxylem and protoxylem tracheids. The specimens are established as a new species of Botryopteridium Doweld, a substituted name for Botryopteris Renault due to its later homonym with Botryopteris Presl. Botryopteridium sinensis./i, sp. nov. displays a combination of features that were previously known individually from different species within Botryopteridium. Although information on its stem morphology is unknown, the new species is suggested to be a small tree-fern living in the forest understory. Moreover, the new plant shows a strong resemblance to late Paleozoic catenalean ferns including Rastropteris, Skaaripteris, and several basal osmundalean genera, thus providing an evolutionary link between members of the first and second evolutionary radiation of Paleozoic ferns.
