03E3EF3FFFDB0435B6AC70AA83498729.taxon	discussion	Note on the type of Brachystemma calycinum: — Don (1825: 216) described the genus Brachystemma and listing one species (B. calycinum D. Don) which is therefore the generitype of the genus (see Art. 10.1 - Note 1 of ICN). Don (1825), after a detailed description reported “ Hab. in Nepalia. Wallich ” so referring to a Wallich’s collection. According to Stafleu and Cowan (1988: 38), Don’s Prodromus is based on Wallich’s specimens preserved at BM, CGE, FI, LINN (Smith’s Herbarium), and PR and “ perhaps in various other herbaria ”. I traced 7 Wallich’s specimens at BM, CAL, E, and K. Wallich (1829 – 1849) mentioned two localities (Napalia and Pandua) in his “ Numerical List ” but Don (1825) described the genus based on specimens collected from Nepal. Hence, only 4 out of 7 specimens found (those collected in Nepal) can be considered as original material for B. calycinum. They are: K 000568116 (http: // apps. kew. org / herbcat / getImage. do? imageBarcode = K 000568116), K 000568119 (http: // apps. kew. org / herbcat / getImage. do? imageBarcode = K 000568119), BM 000583343, and E 00317572. Hara & Williams (1979: 53) reported “ Wall. s. n., ann. 1819 ” as a type of B. calycinum. According to the Art. 7.11 of ICN (see also Prado et al. 2015) these two authors inadvertently lectotypified Don’s name.	en	Kumar, Anant (2023): A new variety of Brachystemma calycinum (Caryophyllaceae) from West Bengal, India with notes on its typification.
