• Lectotype: "Australia. Queensland. COOK DISTRICT: Rockinghams Bay [Stone River], [24 October 1866], [J. Dallachy s.n.] (lecto [here designated]: K 000872971 i.d.v.; isolecto: BRI [AQ333092: with ‘Stone River J. Dallachy 26.10.1866; ex herb. Melbourne’], MEL 113385 [with ‘Stone River 24 October 1866’], MEL 113386 [with species description by Mueller], MEL 113387 [with ‘Rockingham’s Bay’])."

• Text: "Mueller (1868) stated that his species was based on material from ‘Rockingham’s Bay. Dallachy’. This collection appears to have been fragmented and mounted as five separate accessions at MEL, BRI and K. The best of the MEL specimens (MEL 113385 with some flowers attached to a leafy stem; labelled as the holotype and with cross referencing to MEL 113386 and MEL 113387) has the location as ‘Stone River’ and a date of 24 October 1866, both written in Dallachy’s hand. MEL 113386 (labelled as an isotype) has a description by Mueller, but no locality, date or collector indicated. MEL 113387 (labelled as possibly an isotype) consisting of three separate leaves and a bit of stem has no description by Mueller, the locality ‘Rockingham’s Bay’, no date and no collector indicated. The material on these three sheets would have originally been unmounted and in folders all kept together at MEL. The sheet at BRI [AQ333092] has a label hand-written by S.T. Blake and states ‘Stone River J. Dallachy 26.10.1866; ex herb. Melbourne’; it comprises two loose leaves and a bit of stem. The sheet at Kew (K 000872971) is an excellent specimen, bearing a Botanical Museum of Melbourne label with ‘Rockinghams Bay’ in Mueller’s hand, but no collector and no date. It is annotated as being received by Bentham in 1868 and is the material he cited (Bentham 1868: 339); perhaps it was meant to be returned to MEL, but this never occurred. Because the five specimens are separately accessioned, with different data and no clear cross referencing between them (apart from the three MEL specimens and this cross referencing would only have been done when the material was mounted), it is necessary to select a lectotype for this name. The specimen at K is easily the best of these, despite the lack of indication of a collector or collection date (although it does say ‘Rec. 1868’). The other four sheets are regarded as isolectotypes."
