Colloquium: The Utility of Pollen in Systematic and Morphological Studies: A Celebration of the Life of John J. Skvarla

Hong, Wang [1], Wortley, Alexandra [2], Blackmore, Stephen [2].

Palynology and systematics of Crepidinae and Lactucinae (Asteraceae: Cichorieae), with an emphasis on Chinese taxa.

The extensive pollen morphological diversity of the Cichorieae has been demonstrated in previous studies, which have also shown that in some cases palynological characters can contribute to our understanding of inter-generic relationships. This paper extends the range of genera for which palynological information is available in two predominantly Old World sub-tribes, Crepidinae and Lactucinae. All of the genera discussed were found to produce pollen belonging to previously described pollen types. However, the inclusion of certain previously under-studied Asian species, especially from China, provides useful new information about the extent of pollen morphological diversity within and between genera in these sub-tribes, and may contribute to a better understanding of the systematics of these groups.
