A preliminary index of chromosome numbers for spermatophytes indigenous to Tasmania is presented, with reference citations. This
compilation includes reports for 166 species provenanced from Tasmanian material, many previously published, and also 55 unpublished
results (mostly from the work of WDJ). Selected reports of species indigenous to Tasmania but derived elsewhere (usually material from
New Zealand or the Australian mainland) are also included as a basis for further study. In total, chromosome numbers are listed for 400
species (409 taxa, including subspecies and varieties) out of a total estimated spermatophyte flora of 1568 described indigenous species.
Ten of the 108 families have been examined in some detail (>45% of species), but the four most speciose families (62511568 species;
Orchidaceae, Asteraceae, Poaceae and Cyperaceae) have a total of only four Tasmanian reports, despite highly variable chromosome complements.
Five other speciose families (Apiaceae, Brassicaceae, Juncaceae, Rhamnaceae and Scrophulariaceae) have no Tasmanian reports
despite demonstrating cytological variability at generic, inter- and intra-specific levels. Further cytological investigation of these taxa is
essential for a clearer understanding of the Tasmanian flora.
