A genus of evergreen or deciduous shrubs and climbers with diverse growth habits, from minute alpine specimens that form low creeping mats to large, rampant vines. They are native to the Southern Hemisphere and have been naturalised elsewhere by cultivation and by distribution by birds. Cultivated species include M. complexa, also known as Australian ivy or Australian maidenhair vine. This is grown for its dense masses of interlaced stems carrying small, dark green leaves and waxy white fruits. They prefer shelter and will need support to scramble up.
