Florida torreya (Torreya taxifolia)
This is the second Florida-specific tree on the list, as well as the second yew — in fact, this critically endangered tree is also known as the stinking yew because its leaves, when crushed, give off a turpentine odor. These slow-growing trees, which can be 40 feet tall and 20 feet wide, are native to a 40-mile stretch of the Appalachicola River in northern Florida, though they are rarely found in the wild, according to the University of Florida IFAS Extension.
The Florida torreya, an evergreen conifer tree, has seen a 98 percent decline in population within the last three generations, according to IUCN. Fewer than 600 individual trees remain.
