A taxonomic review of Homoranthus and two new species of Darwinia (both Myrtaceae, Chamelaucieae)

Abstract

The genus Homoranthus Cunn. ex Schauer is reviewed and its distinction from Darwinia Rudge and Verticordia DC. reassessed. Excessive weighting of the degree of incision of the sepal margin has obscured the inter- and intrageneric relationships which are evident when other features are considered. The following new species of Homoranthus are described: H. biforus, H.floydii, H. lunatus, H. melanostictus, H. monianus, H. prolixus and H. zeteticorurn; and the following new combinations made for species transferred to it from other genera: H. cernuus, H. decumbens, H. homoranthoides, H. porteri and H. thomasii. Two new species of Darwinia are described: D. briggsiae from New South Wales and D. salina from South Australia.
