Taxonomic notes: There are three species whose occurrence in S.Aust., although reported, is improbable: P. aspera Sieber ex DC., Prod. 2:33 (1825). (Rough) hazel pomaderris. (Ill. Costermans (1981) Native trees and shrubs of south-eastern Australia, p. 217.). Leaves usually 5-6 (but up to 10) cm long; flowers in panicles; sepals 1.5-2 mm long. --P. apetala sensu J. Black, Fl.S. Aust. 546 (1952), non Labill. This species was collected "near Gladstone" by an unknown collector (J. Black (1952) knew it from two specimens from this locality but only one is preserved in AD). This locality is some 550 km from any other locality for this species and, as it has not been recollected in S.Aust. and as there are several towns of the same name elsewhere in Australia, it is considered unlikely to be native to or naturalised in S.Aust. P. myrtilloides Fenzl in Endl., Enum. Pl.Hügel 22 (1837). The only species reported for S.Aust. with narrow-linear petals; calyx silky. Recorded last century from KI and GT, but there is no specimen in AD and its occurrence is thought to be improbable. P. vacciniifolia Reisseck in F. Muell., Linnaea 29:266 (1858). Round-leaved pomaderris. Petals broad; calyx hoary. Twice reported in the 1890s from SL. There is no specimen in AD and the nearest known localities are east of Melbourne. A plant of cultivated origin from the SE has been tentatively identified as belonging to this species. A specimen under this name in the Schomburgk Herbarium of unknown origin has been reidentified as P. forrestiana.
