paleobotany (affiliated coll.)
Herbarium staff and students participate in diverse projects spanning traditional morphological plant systematics, floristics, plant anatomy, molecular analysis and pollination ecology. Our major focus areas include the plant families Orchidaceae, Ericaceae and Melastomataceae, Angiosperm family phylogeny, Florida floristic inventories and cultivated plant systematics.

Soltis lab (affiliated program)
Our computer databases and image galleries are being developed with a thematic focus. The collections catalog includes ca. 40,000 searchable specimens. Digital image sets include the herbarium's type specimens, potentially invasive, insectivorous, poisonous and endangered plants of Florida and the Floristic Inventory of Kanapaha Botanical Gardens.
