| Abstract Detail
A Symposium in Honor of Sherwin Carlquist DeVore, Melanie L. [1]. Carlquist's Service to Synantherology. It would be an understatement to say that Sherwin Carlquist's most recognized contributions to the plant sciences have been in the area of comparative wood anatomy. However, his contributions to the systematics of the Compositae and his detailed anatomical studies of the family have been undernoted. Carlquist's concept of woody ancestral Compositae, initially recognized as a significant contribution, has gained additional support from both subsequent morphological and molecular phylogenetic studies. The recognition of two tribal groupings within the family(Asteroideae and Cichorioideae), first suggested by Carlquist was an essential stepping stone towards future phylogenetic studies of the family. Carlquist's work on Mutisieae, particularly those of the Guyana Highlands, resulted in the proposing the concept of a basic pattern in pollen in Compositae "upon which variations have taken place". Additional surveys of Compositae pollen, as well as the distribution of pollen types on the topology of trees, have supported this concept. The current wealth of phylogenetic studies of Compositae continue to elucidate the value of anatomical studies for resolving relationships within the family. Conversely, these phylogenetic studies also provide a framework for a renaissance in examining anatomical evolution within the family.
