Summary An investigation of the style base, filament collar, endothecium, and carpopodium was conducted in order to evaluate their utility as generic markers in the tribe Astereae. The distribution of character states for these microcharacters does not correspond to generic (or, in some cases, infrageneric) limits as they are recognized by recent authors. Use of the microcharacters considered here for delimiting genera would necessitate widespread realignments of the genera in the tribe and would obscure relationships amongst species groups.
