basionym: Thelymitra x merraniae Nicholls legitimate

• Comment: Nicholls attributes this name to W.H.Nicholls, Vict. Nat. 46: 139 (1943), where he discusses the reduction of T. merraniae Nicholls to a form of T. ixioides but does not definitely associate the species name and final epithet as required under ICN Art. 35.2 (Shenzhen Code, 2018).
