Macarthuria australis Hügel ex Endl., Enum. Pl.: 11. 1837

Type: No type material of Macarthuria australis has been located at herb. W, where Hügel’s herbarium is held (Stafleu & Cowan 1979), and it is believed to have been destroyed during the Second World War (E. Vitek pers. comm.). Searches for type material at other herbaria (e.g. B, BR, CGE, HBG, K, LE, M, MEL, P and WRSL) where duplicates may exist have also been unsuccessful. A neotype is therefore nominated for M. australis. It agrees well with the protologue, except that stamens are consistently eight rather than ten, the staminal ring is white to cream (both in dried and live material) as opposed to pink, and the ovary is strictly 3-locular rather than 3- or 4-locular; this is also consistent for all other material of this species examined by the present author. Endlicher appears to have misinterpreted these characters, or perhaps based his observations on teratological material, as was suggested by Steetz (1848) and Harvey (1855).1
