Climbers
The ability to climb and scramble over the ground or other plants is the only characteristic shared by plants in this category.

Aeschynanthus lamponga Miq.
Frost-tender, trailing evergreen perennial with ovate leaves and axillary clusters of tubular orange-red to scarlet flowers, to 5cm long, in summer. To 30cm. [RHSD, Hortus].
Aeschynanthus longicaulis Wall. ex R.Br.
Frost-tender. Semi-trailing perennial with oval, light green leaves, with dark marbling above and red beneath, and solitary, axillary, greenish-yellow flowers, with maroon-or brown-tinged throats, from summer to winter. To 60cm by 90cm. [RHSD, Hortus].
Aeschynanthus longiflorus (Blume) DC.

Aeschynanthus parasiticus (Roxb.) Wallich.

Aeschynanthus pulchra G.Don
Frost-tender, epiphytic climber with thin, rooting branches, oval, toothed, dark green leaves and terminal corymbs of 6-8, hooded, bright red flowers with a yellow throat from summer to winter. [RHSE, Hortus].
Aeschynanthus pulchra G.Don var. majus
See Aeschynanthus pulchra G.Don for a description of the type. Probably a variety of Aeschynanthus pulchra with larger flowers. I have found no specific reference to this variety.
Aeschynanthus ramosissima Wall. ex R.Br.
Generally regarded as synonymous with Aeschynanthus parasiticus (Roxb.) Wallich. which see for a description. The Gardeners Chronicle described A. ramosissimus as resembling A. grandiflora (A. parasiticus), but not such a strong grower and with a tendency to branch more than the type. [Gard. Chron. 1841].

Allamanda cathartica L. var. grandiflora L.H.Bailey & Raffill.
For a description of the species see Allamanda cathartica L. Grandiflora freely produces flowers with trumpets almost twice as large as the type, sometimes more than 10cm across. [RHSD].
Allamanda cathartica L. var. schottii L.H.Bailey & Raffill.
For a description of the species see Allamanda cathartica L. Schottii has yellow trumpets with a dark striped throat. Tends to be bushier than the species. [RHSD].
Allamanda neriifolia Hook.
Frost-tender, semi-erect, evergreen semi-climber with oblong leaves in whorls of 2-5, and deep golden yellow flowers streaked with orange-red in summer. To 1.5m. [RHSD, Hortus].
