Kirk (Stud. Fl. 1899, 12) describes his var. angustatus from plants collected on Mount Maungatua, Otago, collected by Petrie. Lvs narrow-oblong, 2-4 cm. long, petiole pilose, pinnae deeply incised; scapes very slender, pilose; fls small. Kirk, however, thought his var. should probably be placed under R. gracilipes.
