Three new combinations of Pterostylis (Orchidaceae)

Janes et al. (2010) presented a molecular phylogenetic study of subtribe Pterostylidinae Pfitzer and concluded that the species in the tribe should be placed in one genus Pterostylis R.Br., and not the 16 genera as proposed by Szlachetko (2001) and Jones & Clements (2002) (see review in Janes et al. 2010). A new classification system for the tribe with one genus, two subgenera and 10 sections was described by Janes & Duretto (2010). Janes & Duretto (2010) also transferred seven species from various genera to Pterostylis and thus for the first time in several years workers have been able to apply formal names in Pterostylis to all species placed in subtribe Pterostylidinae.
