• Comment: Mueller lists "Microstylis Bernaysii = M. congesta, ...". Microstylis bernaysii F.Muell. was previously accepted by Mueller on p. 111 of the Systematic Census (1882) but Microstylis congesta (Lindl.) Rchb. is the only species treated in Mueller's Second Systematic Census on p. 188 (1889). Therefore Microstylis congesta is here treated as being the accepted name in this Supplement with M. bernaysii in synonymy.
