• Comment: Mueller lists "Pterostylis turfosa = Pterostyls barbata". Pterostylis turfosa Endl. and Pterostylis barbata Lindl. were both previously accepted by Mueller on p. 113 of the Systematic Census (1882) but P. barbata Lindl. was the only one treated in Mueller's Second Systematic Census p. 186 (1889). Therefore P. barbata is here treated as being the accepted name in this Supplement with P. turfosa included in synonymy.
