1954. Trisepalum lineicapsa C.E.C.Fisch., Bull. Misc. Inform. Kew. 1928 (7): 276. 1928. Lectotype (firststep designated by Weber et al., 2000; second-step designated here): INDIA, Mizoram (then Assam), Lushai hills, Aijal (Aizawl), 1225 m, September 1927, Mrs N.E. Parry 79 (K [K000820540 digital image!]; isolecto K [K000820539, K000820541 digital images!]).

Notes: Fischer (1928) described Trisepalum lineicapsa based on collection ‘ N.E. Parry 79’ from the Lushai hills of Mizoram, India. The collections associated with C.E.C. Fischer are housed at K ( Stafleu & Cowan, 1976). We could locate three specimens ‘ N.E. Parry 79’at K (K000820539, K000820540, K000820541), all referred here as syntypes (Art. 9.6 of the ICN, Turland et al., 2018).

Weber et al. (2000) cited “ Parry 79 ( K; type of T. lineicapsa )” without specifying a single sheet, hence a second-step lectotypification is desirable (Art. 9.17 of the ICN). Of the three sheets at K, K000820539 bears shoots and fruits. The collector’s label on the bottom left reads, “Lushai hills, Dydimocarpus species […… illegible], Aijal 4000 ft, No. 79, Sept. 1927, flowers claret colour”, and the Kew label on the bottom right with the sheet apparently in Fischer’s handwriting, “ Trisepalum lineicapsa Fischer, Coll. Mrs. N.E. Parry No. 79, Aijal, Sept. 1927, Lushai Hills, Assam 4000 ft ”. The sheet K000820540 has a branch with flowers, whereas K000820541 has flowering shoots. Both these sheets are also marked as ‘ bis’ in ink, indicating that they are duplicates, and carry the same herbarium label as K000820539 . The sheet K000820540 is designated here as the second-step lectotype , and K000820539 and K000820541 as isolectotypes .
