Clematis
genus of plants

Clematis is a genus of about 380 species within the buttercup family, Ranunculaceae. Their garden hybrids and cultivars have been popular among gardeners, beginning with Clematis 'Jackmanii', a garden staple since 1862. More cultivars are being produced constantly, mainly of Chinese and Japanese origin.
Species names
Most species are known as clematis in English, while some are also known as:
traveller's joy, a name invented for the sole British native, C. vitalba, by the herbalist John Gerard (1545–1612);
virgin's bower for C. terniflora, C. virginiana, and C. viticella;
old man's beard, applied to several with prominent seedheads;
leather flower for those with fleshy petals; or vase vine for the North American Clematis viorna.
Etymology
The genus name Clematis is from Ancient Greek κληματίς : clēmatís, ("a climbing plant") from κλήμα : klḗma – 'twig, sprout, tendril'.
Botany
The genus is composed of mostly vigorous, woody, climbing vines / lianas. The woody stems are quite fragile until several years old. Leaves are opposite and divided into leaflets and leafstalks that twist and curl around supporting structures to anchor the plant as it climbs. Some species are shrubby, while others, like C. recta, are herbaceous perennial plants. The cool temperate species are deciduous, but many of the warmer climate species are evergreen.
This brief starts where responsible research should: with the source description of “Clematis” as genus of plants. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of plants. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q157634. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1862, 1545 and 1612.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
