*Hedera Linnaeus. Ivy.

Key to Hedera

A genus of 15 species, lianas, distributed from Mediterranean Europe west to e. Asia (Plunkett et al. 2018b).

ID notes:The leaves of Hedera are dimorphic, sometimes confusing observers; "juvenile" leaves (those of the sterile branches) are about as wide as long and (in H. helix) palmately 3-5-lobed, those of the fertile branches (less commonly seen) are obovate or elliptic.
