What is the world's rarest plant?

Answer 1

Encephalartos woodii

It's one of the rarest plants in the world: a tall palm with dark, glossy leaves, once found only on a single south-facing slope on the edge of the Ngoye forest in Southern Africa. It's extinct in the wild and produces no seeds - the only plants ever found were males. People have begun crossing it with its closest relative to produce 'pups' that, after 3 generations, are almost pure E. woodii again.
