Taxonomic notes on Anoectochilus (Orchidaceae)
摘要
Anoectochilus brevilabris and similar species have been much confused. Three former synonyms, A. griffithii, A. tridentatus and A. chapaensis, are here reinstated. Anoectochilus dulongensis and A. annamensis are treated as new synonyms of A. brevilabris and A. baotingensis respectively. The duplicate of the lectotypes of A. chapaensis belongs to A. longilobus. In addition, A. griffithii is recorded from China for the first time. A key to eight similar Anoectochilus species is provided.
