Species of interest. Persoonia inconspicua has a distribution

centred around Southern Cross and the Jingaring record

represents a significant range extension. A presumed hy-

brid between Dryandra pteridifolia ssp pteridifolia (southern

sandplains) and Dryandra pteridifolia ssp vernalis (northern

sandplains) occurs on the reserve (taxonomic status to be

determined). The reserve locality is also the distribution

limit for Lagenophora huegelii, Patersonia occidentalis, Hibbertia

hypericoides,  Sowerbaea laxiflora (most eastern margin);

Adenanthos argyreus,  Conostylis petrophiloides,  Grevillea

cagiana,  Logania tortuosa (most western margin); Kunzea

micromera, Banksia violacea (most northern margin) and Aca-

cia acuaria, A. anarthros and Grevillea eriostachya (most

southern margin). This suggests that Jingaring Nature

Reserve was part of a possible refugium where past cli-

matic fluctuations have caused the maximal species

interactions  i.e. a central meeting point for potential

speciation (Hopper 1979).  In these terms, the reserve is a

significant ‘evolutionary showcase’.
