Lamiaceae

The past year has been the first of a 3-year project funded by the Australian Biological Resources Study (ABRS), which is led by Trevor Wilson collaborating with Barry Conn and Murray Henwood (University of Sydney). This project is the first rigorous, comprehensive revision of the subfamily Prostantheroideae (Lamiaceae). The year began with the publication of the molecular phylogeny of Prostanthera in Australian Systematic Botany journal, as well as the reduction of the genus Wrixonia to Prostanthera. Collections for DNA analysis of the subfamily Prostantheroides were obtained Western Australia and analysis of these data has been undertaken for the development of a molecular phylogeny of the this endemic Australian subfamily. Fertile collections of a wide sample of Prostantheroideae will be used for next years' investigation of floral evolution using the phylogeny of Prostantheroideae.

Loganiaceae

Kerry Gibbons (PhD student, University of Sydney), together with her supervisors, Drs Barry Conn and Murray Henwood (University of Sydney) investigated the phylogeny of the tribe Loganieae (Loganiaceae). A molecular phylogeny confirmed that the previous reduction of Labordia (restricted to Hawaii, USA) to the wide-spread genus Geniostoma was correct. It also resulted in the establishment of the new genus Adelphacme, endemic to Western Australia. Charles Foster (BSc. Hons. student, University of Sydney) studied the phylogeny of Logania using molecular data, resulting in a joint paper with Barry Conn, on the status of Logania imbricata from New Caledonia. They concluded that this species was a member of the genus Geniostoma. Their research now establishes that Logania is an endemic genus of Australia.
