Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Brief description
Scrambling liane with pale green flowers, smooth-edged or with 1-2 sharp-tipped lobes leaves which are covered in brownish down when young
Distribution
Endemic. North Island. South to Hawkes Bay in the east, to ?? in the west.
Habitat
Lowland forest and forest margins
Features
Evergreen woody climber with main stems to 3 m or more tall; branchlets finely grooved, pilose when young. Leaves 3-foliate, opposite; petioles c. 3 cm long, pilose-pubescent. Leaflets pubescent-pilose with fulvous hairs especially beneath; on petiolules c. 1 cm long; midvein and secondary veins visible above, more obvious below; leaflet lamina 1.5-4 x 1-2 cm, ovate, entire or crenately toothed or lobed, submembranous, dark green to yellowish-green, tip acute, base usually cordate, undersides paler. Juvenile leaves larger, thinner, irregularly lobed and sometimes serrate. Inflorescences unisexual, conspicuous, in axillary dichasial cymes, few-flowered, up to 8 cm long, inflorescence bracts linear-oblong, paired, united, inserted above middle of peduncle, fulvous. Flowers slightly fragrant. Male 1-2(-2.5) cm diam., sepals 5-8, narrow-oblong to elliptic-oblong, subacute, imbricate, glabrous above, hairy beneath, 9-12(-22) x 2-5 mm, yellowish; stamens many, anthers 0.7-1 mm long, filaments glabrous., up to 1 cm long. Female 5-8 sepals, imbricate, yellowish, glabrous above, hairy beneath, elliptic-ovate, 8-13(-15) x 2-3(-6) mm; staminodes few. Achenes hairy, elliptic, narroweed to apex, compressed, margin thickened and distinct, surface finely ridged, 2.6-3.4(-3.6) mm long, styles 20-26(-30) cm long at fruiting, white-plumose for most of length, short hairs at base.
Similar taxa
Similar to other climbing yellow-or green-flowered clematis species that have large leaves. It can be distinguished most easily from C foetida by the strong pleasant smell of that species (and also by the hairy rather than downy sepals and petals). C. forsteri has young leaves that are either glabrous underneath, or occ. with white (rather than brownish) hairs (the anthers are also larger in this species).
Flowering

Fruiting

Life cycle
Pappate achenes are dispersed by wind (Thorsen et al., 2009).
Etymology
clematis: From the Greek klema ‘vine’, alluding to the vine-like habit of many species
cunninghamii: Named after Allan Cunningham (1791 – 1839) who was an English botanist and explorer, primarily known for his travels to Australia (New South Wales) and New Zealand to collect plants.
