Recognition of Hysterobaeckea as a genus of Myrtaceae tribe Chamelaucieae

Abstract

Rye, B.L. Recognition of Hysterobaeckea as a genus of Myrtaceae tribe Chamelaucieae. Nuytsia 25: 209-218 (2015). Baeckea behrii Schltdl. is selected as the lectotype for B. subg. Hysterobaeckea Nied., which is raised to the generic level as Hysterobaeckea (Nied.) Rye. New combinations are made for the three named species that belong to the genus as now defined, and a lectotype is selected for one of those species, B. ochropetala F.Muell. The three new combinations are H. behrii (Schltdl.) Rye, H. ochropetala (F.Muell.) Rye and H. tuberculata (Trudgen) Rye. The distinguishing characters of the genus are outlined and a generic key given for the group to which it belongs. Section name, size and distribution Species listed Current name sect. Babingtonia 12 species, WA Baeckea camphorosmae (Lindl.) Endl. Babingtonia camphorosmae Lindl. sect. Harmogia 6 species, Australia and New Caledonia Baeckea behrii (Schltdl.) F.Muell. B. virgata (Forst.) Andr.[Babingtonia behrii (Schltdl.) A.R.Bean] Sannantha virgata (Forst.

An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae: 5. Hysterobaeckea

“…Hysterobaeckea (Nied.) Rye has only recently been established as a genus (Rye 2015a) rather than a subgenus (Niedenzu 1893). It belongs to the tribe Chamelaucieae DC.…”

“…of Myrtaceae and occurs in southern mainland Australia. Recombinations were made in Rye (2015a) for three named species of Hysterobaeckea but most of the Western Australian taxa remained undescribed. Eleven new Western Australian members of the genus are described here, using the same methodology as in previous papers of this series (see Rye 2013b).…”
