Proposal for delineation of Botanical regions in Australia.

A division of Australia into 33 botanical regions is proposed. The regions may be useful for describing and illustrating geographic distributions of plant taxa, for arrangement of specimens in herbaria, or for data base construction. The proposed common boundaries of the botanical regions are meridians of longitude and parallels of latitude, generating regions comprising from 10 to 44 1-degree grid cells. The botanical regions proposed are thus compatible with grid cell mapping systems.
