Floristics is the study of plants of geographical regions. It is a branch of phytogeography,[1] which technically makes it a branch of botany, geography, and a subbranch of biogeography. Harvard University has a history of research with early contributions. For example, Asa Gray was a Harvard researcher who studied the plants of North America and its connections to Asia.[2]
Floristics is essential to understanding floristic diversity across the world.
