Abstract: The lily family (Liliaceae) in its strict sense consists of just 15 genera that are distributed almost entirely across the temperate Northern Hemisphere, but this monocot clade is of considerable economic and horticultural importance worldwide. The genera Tulipa and Lilium are especially important, yet continue to remain shrouded in taxonomic uncertainty. However, recent systematics studies using modern phylogenomic methods have greatly advanced our understanding of the classification, evolution, development, and historical biogeography of these showy and popular flowering plants. Today the family is divided into four subfamilies: Tricyrtidoideae with four genera; Medeoloideae with two genera; Lilioideae with eight genera; and Calochortoideae, for Calochortus alone. This symposium will bring together botanists from North America and Asia who are collaborating to address fundamental questions of lily systematics and conservation biology at all taxonomic levels from family to species populations.

Speaker 1: Kenneth M. Cameron Wisconsin State Herbarium, University of Wisconsin-Madison USA "Plastome structure, phylogenetics, and historical biogeography of Liliaceae subfamily Streptopoideae"

Speaker 2: Pan Li Zhejiang University, Hangzhou, China "Comparative genomics and phylogenetic analyses of Liliaceae"

Speaker 3: Thomas J. Givnish Department of Botany, University of Wisconsin-Madison, USA "Evolution, Geographic Spread and Floral Diversification of the Genus Lilium with special reference to the lilies of North America"

Topics (Up to three): Phylogenetics and Phylogenomics

Topic 2: Biogeography / Phylogeography

Topic 3: Systematics

Justification: Liliaceae are among the most charismatic of angiosperms. Horticulturally they are a multi-million dollar industry and biologically they represent a model system to investigate a wide variety of scientific topics. Our symposium will bring together women and men at different career levels (postdoc to senior professor) from at least North America and Asia. We list three speakers from the USA and China who are excited to participate, and know of at least three more who will register. Together these botanists will present their most recent findings based on cutting-edge phylogenomic methods that bridge at least five IBC target topic areas.
