A naturally occurring hybrid between Rubus parvifolius and Rubus moluccanus var. trilobus, known as Rubus x novus, has characters intermediate between these two species; the leaves are either simple and deeply 3- or 5-lobed or irregularly 3-foliolate, 2-7.5 cm long, found north from Orbost, Vic., to Mackay, north Qld.
