Systematics and biology of Hemigenia R.Br. and Microcorys R.Br. (Lamiaceae).

Abstract

The genera Hemigenia R.Br. and Microcorys R.Br. (Lamiaceae, tribe Westringieae) have not been revised since 1870 and the existing taxonomy is inadequate. The current generic classification requires re-evaluation in light of more detailed knowledge of comparative morphology. The generic status of the related genera Hemiandra R.Br. and Westringlia Sm. also needs to be tested, as these genera share morphological characters with Hemigenia and Microcorys. In this thesis a new classification is discussed, but further data are required before this can be finalised. In particular, multiple DNA markers need to be sequenced with a slightly larger sample of species.
