Recent molecular studies of Prostanthera (Lamiaceae) showed a close evolutionary relationship among P. phylicifolia s. str., the critically endangered P. gilesii and a population of uncertain identity from New South Wales. In this study, analyses of genomic and morphological data identified the presence of three discrete entities that warrant specific recognition. A new species of immediate and critical conservation concern is identified, and methods for conservation are reviewed.

Macroalgae in family Characeae occur in inland waters throughout Australia. Species of Chara, Lamprothamnium and Lychnothamnus (tribe Chareae) that occur in Australia’s Northern Territory have been reviewed, revised and described here, resulting in 22 species for the region.
