NOTE ON TRICHOSANTHES KHASIANA

Renner & Pandey (2013) placed T. khasiana Kundu as an accepted species based on Jeffrey (1982) and De Boer & Thulin (2012) and cited its type as a staminate specimen (http://www. kew.org/herbcatimg/505009.jpg) without attributing a reason. In fact, there are two syntypes, a staminate (J.D. Hooker & T. Thomson s.n.) and a pistillate specimen (J.D. Hooker & T. Thomson 617) housed at K (annotated by Kundu), which represent two different taxa. The type that most closely matches the original description or diagnosis is the pistillate one ( Fig. 4 ), hence the name T. khasiana is lectotypified here (ICN Art. 9.3 and 9.14, Turland et al. 2018). The staminate specimen is a yet-to-be described taxon of Trichosanthes .
