Botany
Since its inception as a public garden, the Morris Arboretum has served as a center for botanical research. Research staff at the arboretum study the evolution, phylogenetics, systematics/taxonomy, anatomy and morphology of plants. The Morris Arboretum also has a long-standing research program in floristics, or the study of what plants grow in a certain place in a particular time frame, with a major focus on the flora of Pennsylvania.
