Abstract
A new species of Bolbitis, B. lianhuachihensis sp. nov., was found in central Taiwan. It most resembles B. virens var. compacta and B. hainanensis. A phylogenetic tree of Taiwanese and other Asian species of Bolbitis species supports the recognition of the new species. Morphologically, the combination of anastomosing venation and fewer sterile pinnae are critical characters to discriminate B. lianhuachihensis from other Taiwanese Bolbitis species. Bolbitis lianhuachihensis can be further distinguished from B. virens var. compacta and B. hainanensis 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 Bolbitis is also provided.
Keywords: Ferns, Taiwan, taxonomy, venation

Bolbitis lianhuachihensis morphologically resembles B. virens var. compacta and B. hainanensis, from which it is distinguished in having lanceolate sterile pinnae and no free veinlets in areoles of sterile fronds.
Etymology: The specific epithet ‘lianhuachihensis’ refers to the type locality [Lienhuachih, Nantou County].
Common name (assigned here): Lian Hua Chih Shih Jyue (蓮華池實蕨; Chinese name).
