Detailed description
A slender low-climbing evergreen woody climber. Leaves are hairy on both sides, trifoliolate and dull green.
Similar taxa
The wider green hairy sepals (petals are not present in Clematis species) distinguish Clematis marata from the very similar C. quadribracteolata, which has narrow purple sepals that are glabrous on the inner surface. When not in flower they are more difficult to distinguish, but C. marata leaflets and branchlets are hairier. The distribution of these two species overlaps throughout the eastern South Island.
Distribution
Endemic to South Island. Found in Marlborough (upper Awatere Valley), Canterbury, Otago, Southland (Te Anau Downs) and Stewart Island.
Habitat
Apparently restricted to river terraces, rock outcrops and dry hillsides and scrub habitats.
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.

Taxonomic notes
Clematis marata and C. quadribracteolata were treated by Allan (1961) as parts of a variable complex. Joe Cartman showed that they are distinct species, and provided descriptions in Canterbury Botanical Society Journal 20: 36-37 (1986).

Regional conservation statuses
The regional threat classification system leverages off the national assessments in the NZTCS, providing information relevant for the regional context. Otago conservation status information is sourced from the “Regional conservation status of indigenous vascular plants in Otago” Jarvie S et al. (2024) report.
