An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae. 2. Cyathostemon
TRUDGEN, MALCOLM E. AND RYE, B.L.
Three new species of Cyathostemon Turcz. are described, illustrated and mapped, and a key is given to the seven named species in the genus. The new species are C. divaricatus Trudgen & Rye, C. gracilis Trudgen & Rye and C. verrucosus Trudgen & Rye. This has reduced the number of taxa known by informal names to seven, most of which belong to a difficult species complex that needs a great deal more work to resolve.
