Species

Clematis (from Ancient Greek klematis, a climbing plant, probably periwinkle) is a genus of mostly vigorous climbing lianas, with attractive flowers. Some species are shrubby, and some others are herbaceous perennial plants. They are found throughout the temperate regions of both hemispheres, and also in mountains in the tropics. The cool temperate species are deciduous, but many of the warmer climate species are evergreen.

Most species are known as Clematis in English, while some are also known as traveller's joy, leather flower, vase vine and virgin's bower, the last three being names used for North American species.

One recent classification recognised 297 species of clematis. Unsurprisingly, therefore, modern taxonomists subdivide the genus. Magnus Johnson divided Clematis into 19 sections, several with subsections [1]; Christopher Grey-Wilson divided the genus into 9 subgenera, several with sections and subsections within them [2]. Several of the subdivisions are fairly consistent between different classifications, for example all Grey-Wilson's subgenera are used as sections by Johnson.

Subgenera of Clematis according to Grey-Wilson:

Clematis, Cheiropsis, Flammula, Archiclematis, Campanella, Atragene, Tubulosae, Pseudanemone, Viorna

Some of these were previously classed as separate genera.

Clematis leaves are food for the caterpillars of some Lepidoptera species, including the Willow Beauty (Peribatodes rhomboidaria).
