Solanaceae Source

A global taxonomic resource for the nightshade family

Nov 6th, 2020 - Lynn Bohs

Next SOL Seminar Online will be presented by Lynn Bohs on ​Spicy Solanaceae potpourri: an update on recent and current projects

Abstract. Much has been learned about the systematics and phylogeny of many Solanaceae since I started my career on the taxonomy of the family over 30 years ago. This talk will summarize some recently completed and on-going projects, including the taxonomy and evolutionary relationships of the genera Capsicum, Lycianthes, Witheringia, and Cuatresia. A collaborative project with Gloria Barboza, Ellen Dean, and Sandy Knapp is examining the species-level taxonomy and phylogeny of the genus Capsicum, which includes the chili peppers and their relatives, and its sister genus Lycianthes. The framework phylogeny of this clade shows that Capsicum is monophyletic, but the monophyly of Lycianthes is unclear due to discordant topologies depending on which genes are analyzed. A spectacular non-pungent new species of Capsicum from the Andes is in the process of being described. Phylogenetic analyses reveal that the morphologically unique species Cuatresia anomala actually belongs to Lycianthes. Another collaborative project with Judy Stone is examining the taxonomy and phylogeny of Witheringia. A framework phylogeny has been completed and there are at least two new species to describe, but the rich and poorly understood diversity of Witheringia in Colombia has not been well sampled.
