Abstract

Rye, B.L. An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae. 4. Malleostemon. Nuytsia 27: 103-120 (2016). The following new species of Malleostemon J.W.Green are described: M. costatus Rye & Trudgen, M. microphyllus Rye & Trudgen, M. nephroideus Rye, M. nerrenensis Rye & Trudgen, M. pentagonus Rye & Trudgen, M. pustulatus Rye and M. uniflorus Rye. A new key is presented for the genus. Malleostemon sp. Kalbarri (L.A. Craven 7083) is reduced to synonymy under M. hursthousei (W.Fitzg.) J.W.Green and unnamed taxa that need further study are noted. Six of the new species have conservation priority. Informal name in MalleostemonYear Current name or comment
