Plagiochila cuspidata Steph. (1918: 144) .

TYPE:— India, “Brit. Sikkim ” [West Bengal], Darjeeling , “Rambhee” [Rambi], 3000 ft., 3 November 1907, pro E. Long, Levier no. 5649, ( G!) (G-010992/ G00064158 p.p.) [lectotype, designated by Inoue, 1965a: G-010992/ G00064158 !; (excluding the material outside the mica sheets); isolectotype: BM] .

Note: Inoue (1965a) believed that the names, P. cuspidata and P. subsymmetrica both had been published in the year 1924 and so presumably felt free to choose P. subsymmetrica for the species. However, Grolle pointed out the nomenclatural error and later, Inoue (1967) corrected P. subsymmetrica as a new synonym of P. cuspidata . Plagiochila cuspidata was published in the year 1918 whereas, P. subsymmetrica in 1921 therefore, P. cuspidata has priority over P. subsymmetrica and Inoue’s choice is unacceptable under ICN, Art. 11 (see also Turland et al. 2018).
