Summary cladogram of phylogenetic relationships in Pterostylidinae based on Clements et al. (2011; modified) and systematic concepts in Pterostylidinae over the past two decades. Solid black circles denote nodes which received maximum support (Bayesian posterior probabilities of 1); grey circles denote moderately supported notes (posterior probabilities of 0.98–0.99). Monotypic taxa are depicted with a single line as terminals. Branches with lower support values (<0.95) are collapsed. Grey boxes highlight taxa which are considered part of Pterostylidinae in the respective classification. Taxa described prior to 2001 and publication years: sect. Catochilus Bentham and Von Mueller (1873); Diplodium Sw. (1810); sect. Foliosae G. Don (1830); sect. Parviflorae Bentham and Von Mueller (1873); Pterostylis R.Br. (1810) and sect. Squamatae G. Don (1830). For historic infrageneric classification systems for Pterostylidinae, see Jones and Clements (2002b).
