Chromosome counts are reported for plants from 171 populations of Australian Compositae; most of these are first reports for the approximately 104 taxa distributed among 37 genera. New generic counts with base numbers indicated include: A stereae — Bellida ( x = 9), Minuria ( x = 9); I nuleae — Angianthus ( x = 12, 13), Calocephalus ( x = 7), Cephalipterum ( x = 12, 14), Craspedia ( x = 11), Gnaphalodes ( x = 10), Gnephosis ( x = 4, 12), Myriocephalus ( x = 6), Isoetopsis ( x = 17); C alenduleae — Tripteris ( x = 8); and A rtcoideae — Arctotheca ( x = 9). Most of the counts were from the tribes Astereae (47) and Inuleae (95). The phyletic import of these data is discussed selectively and comparisons are made with the chromosomal variation found in the Australian desert Compositae with that found in the North American desert Compositae.
