• Type: "Australia. Queensland. PORT CURTIS DISTRICT: near Rockhampton, s.dat., [A.] Thozet s.n. (holo: K 000872972 i.d.v.; iso: BRI [AQ333119: with no. 511], MEL 113557 [with no. 511], MEL 113558 [with no. 511, description by Mueller], MEL 113560 [with no. 511], MEL 560756 [with no. 511])."

• Text: "Bentham (1868) cited a single collection ‘Near Rockhampton, Thozet’ when he described Thozetia racemosa based on a manuscript description by Mueller. There is no evidence that Thozet made multiple collections of the species and his material would have been originally kept at MEL in multiple papers, until Mueller sent some to Bentham [albeit without Thozet’s collecting number 511 attached], presumably with a draft description. In the 1995 revision the holotype for T. racemosa was taken to be the MEL specimen and this has now been accessioned under four different numbers, all with cross-referencing between the sheets. However, Bentham as the describing author would not have seen this material, so the sheet at Kew should be regarded as the holotype with other sheets in BRI and MEL regarded as isotypes, despite some of the ones at MEL being better than the K sheet."
