Clematis viticella L. var. rubra
See Clematis viticella L. for information on the species.  Clematis viticella rubra is probably the red-flowered form mentioned in Curtis’s Botanical Magazine [BM t.565/1802].  ‘Rubra grandiflora’, with large, carmine flowers, is still commonly grown [Hortus].  This form was figured in Flore des Serres [FS p.20/1874] and is used as illustration here.

Some of the more interesting summer-flowering things are the several kinds of Clematis, a tribe of plants with which most cultivators are familiar, as few gardens are to be found that do not possess some of them. [...]
