CONTRIBUTIONS TOWARDS A REVISION OF DAVIESIA (FABACEAE, MIRBELIEAE) .4. D-ULICIFOLIA SENS LAT

Following a morphometric and cladistic analysis of the Daviesia ulicif olia Andrews group (Chandler and Crisp 1997), a new species, D. sejuga ta, is described. It occurs disjunctly in eastern Tasmania and souther n Yorke Peninsula, South Australia, and is closely related to D. arthr opoda F.Muell., differing in a generally more robust habit, thicker fl eshy phyllodes, and larger flowers. Even with this species removed fro m D. ulicifolia, the latter varies considerably over a wide geographic , edaphic and altitudinal range. Daviesia ulicifolia is divided into s ix subspecies based on distinct phenetic and phylogenetic groups delim ited in the earlier study. These are subsp, aridicola (glaucous plants in arid regions), subsp, incarnata (reddish-flowered plants in the Mt Lofty Range, South Australia), subsp, ruscifolia (plants with ovate-a cuminate leaves and orange flowers in Victoria and southern New South Wales (NSW), often at high altitude), subsp. stenophylla (a narrow-lea ved form in northern NSW and Queensland), subsp. pilligensis (ovate-le aved plants on sandy soil in western NSW), and subsp. ulicifolia (a pa raphyletic residual from southeastern states).
