“…During recent surveys in Sri Lanka, the current authors encountered a few species belonging to Nervilia. Fresh specimens were collected and dissected for thorough analysis based on studying the available relevant literature (Seidenfaden & Wood, 1992;Averyanov, 2008Averyanov, , 2010Averyanov, , 2011aAveryanov, ,b, 2013Chen & Gale, 2009;Hsu et al, 2012;Jalal et al, 2012;Gale et al, 2013Gale et al, , 2015Gale et al, , 2016Lin & Chang, 2013;Gale & Watthana, 2014;Lin, 2014) and herbarium specimens in PDA, along with other repositories of online digital specimens at K and P. In Sri Lanka, Nervilia was known to be represented by a single species, N. juliana (Roxb.) Schltr., but its occurrence was believed to be doubtful (Hooker, 1898;Jayaweera, 1981;Fernando & Ormerod, 2008).…”
