The Five-lobed Maple (Acer pentaphyllum) is one of the rarest Maples in the wild known only from a very small and threatened population which was recently rediscovered following its introduction to cultivation in the 1930's from a scarce handful of seed. It is deciduous with deeply cut 5-lobed leaves that are very unmaple-like.
This delicate tree, nearly extinct in the wild and unsurprisingly it is listed as Critically Endangered by the IUCN
