It most resembles B. virens var. compacta and <i>B. hainanensis</i>. A phylogenetic tree of Taiwanese and other Asian species of <i>Bolbitis</i> species supports the recognition of the new species. Morphologically, the combination of anastomosing venation and fewer sterile pinnae are critical characters to discriminate <i>B. lianhuachihensis</i> from other Taiwanese <i>Bolbitis</i> species. <i>Bolbitis lianhuachihensis</i> can be further distinguished from B. virens var. compacta and <i>B. hainanensis</i> by having lanceolate sterile pinnae and absent or fewer free veinlets in small areoles of sterile pinnae. The morphological descriptions, illustration, ecology and distribution of the new species are presented. A key to all Taiwanese <i>Bolbitis</i> is also provided.PhytoKeys69-81https://www.ebi.ac.uk/biostudies/studies/S-EPMC6742672biostudies-literature<i>Bolbitis lianhuachihensis</i> (Dryopteridaceae), a new species from Taiwan.PMC6742672Huang YFChao YSLiu HYHuang YMDong SYfalse<i>Bolbitis lianhuachihensis</i> (Dryopteridaceae), a new species from Taiwan.A new species of <i>Bolbitis</i>, <i>B. lianhuachihensis</i> <b>sp. nov.</b>, was found in central Taiwan.
