Muehlenbeckia adpressa

Muehlenbeckia adpressa, commonly known as climbing lignum, is a prostrate or climbing plant, native to Australia. It has thin red-brown stems up to 1 m in length. The leaves are 1.5 - 6 cm long and 1.5 - 3.5 cm wide. It occurs in coastal areas of Western Australia, South Australia, Tasmania, Victoria and New South Wales.

Taxonomy
The species was first described in 1805 by Jacques Labillardière, as Polygonum adpressum. It was transferred to the genus Muehlenbeckia in 1843 by Carl Meissner. Some sources, including Plants of the World Online, regard M. adpressa as a synonym of M. australis. Others treat them as separate species.
