Shrub to 2 m or so tall with branches and stems forming flattened, green, striated rectangular segments mostly 1-1.5 cm wide. Leaves lanceolate, to 5 cm or more long, growing at the joints and shed before flowering. Flowers in small stalkless clusters, alternating at the joints, pale green. Perianth segments 5, joined at the base and fleshy in fruit. Stamens 8. Stigmas 3; spring. Fruit enclosed by purplish red envelope, containing 3-angled nut. [Muehlenbeckia platyclada (F.J.Muell.) Meissn.]
Occasionally grown for the bizarre flattened photosynthesising stems.
Will grow outside in Victoria but in the tropics cylindrical stems develop and the plant is much larger.
Remarkable flattened striated segmented stems.
