[email protected] Abstract Work on the Global Compositae Checklist has highlighted uncertainties and errors in the nomenclatural parameters of many genera and subgenera described by Henri Cassini. Problems concern rank (subgenus vs. genus); type designation; cor- rect place of valid publication; alternative names; and other miscellaneous issues. An annotated list with correct nomenclatural information for 391 generic names or designations is provided, including types (newly designated here for 17 names) and one new combination (Gyptis tanacetifolia). The current taxonomic disposition of Cassini’s genera and the accepted names for the listed typonyms are consistently mentioned. The familiar names Felicia and Chrysopsis, already conserved, are threatened by unlisted earlier synonyms, and currently used Fulcaldea turns out to be illegitimate. Proposals to deal with these problems by conservation are being presented separately. Keywords Asteraceae; conservation; genera; nomenclature; subgenera; typification INTRODUCTION of valid publication for many of Cassini’s generic names, as well as their nomenclatural status and the identity of their type. Henri Cassini is considered the founder of modern syn- These problems have come to light with incipient work on a antherology (the study of Compositae or Asteraceae; King & Global Compositae Checklist (GCC, www.compositae.org/ Dawson, 1975).
