Abstract

Conn, B.J. (Royal Botanic Gardens, Mrs Macquaries Road, Sydney NSW 2000, Australia) 1997. Four rare and/or threatened new species of Prostanthera Section Prostanthera (Labiatae) from New South Wales. Telopea 7(3): 231–244. Prostanthera askania, P. hindii, P. junonis and P. palustris are described for the first time. Both Prostanthera askania and P. junonis are threatened by urban and industrial development in the Gosford area. Neither of these species is afforded protection because they do not occur within any conservation reserves. Prostanthera junonis is restricted to the Somersby Plateau (Gosford area). Without immediate protection from inappropriate urban and industrial development, this threatened naturally rare species is likely to become extinct in the near future. Although often locally rare, P. hindii occurs in the Wollemi National Park and does not appear to be conservationally threatened. Prostanthera palustris is a rare and possibly threatened species that is restricted to the Bundjalung National Park of north-eastern New South Wales.
