A new species of fern, Pteris pseudoamoena, was discovered in Guangxi Province, China, and Vietnam. It shares morphological similarities with P. amoena and P. mcclurei, but can be differentiated by characteristics such as spores, straw-colored stems, and veins. Molecular evidence suggests that P. pseudoamoena is closely related to P. amoena, P. nakasimae, and P. mcclurei.
A new species of fern, Pteris pseudoamoena (Pteridaceae), was identified and characterized. It is currently found in Guangxi Province, China, and Vietnam. Pteris pseudoamoena shares similar morphological characters with P. amoena and P. mcclurei, but can be distinguished by spores with echinate-tuberculate and auriculate ornamentation, straw-colored stipes, rachises and costae, and mostly free, occasionally interlinked veins. In addition, molecular evidence indicated that the new species is sister to a clade consisting of P. amoena, P. nakasimae and P. mcclurei.
