'Menispermum' from the website Trees and Shrubs Online (treesandshrubsonline.
Climbing, woody or semi-woody plants, with alternate, long-stalked, peltate leaves, and separate male and female flowers. Sepals six; petals six or nine; stamens nine to twenty-four. The black or purple-black fruit encloses one half-moon or crescent-shaped seed – giving the popular name. The plants spread rapidly by means of underground stems, and are easily increased by division. Cocculus is nearly allied, but has the leafstalk attached at the margin of the leaf, and only six stamens.
