Shrub or small tree up to 6 m tall. Branchlets slender, pale yellow-green when young. Leaves opposite, 3-foliolate, on petioles up to about 50 mm long; petiolules very short to 5 mm long. Lamina thinly coriaceous, (50)-70-100 x (20)-30-40 mm, subacute to acute, obovate-cuneate to elliptic- to ovate- or obovate-oblong, entire (all forms may be on same plant). Subfloral leaves may be 2-foliate or single. Inflorescence of often paired axillary cymes, frequently tri-branched, on peduncles approximately 20 mm long; bracts minute, ovate; pedicels approximately 5 mm long. Flowers perfect or unisexual, 8-10 mm diameter. Sepals ovate-oblong, about 1.5 mm long, gland-dotted; petals greenish, ovate-oblong, concavo-convex, about 5 mm long, gland-dotted.

Similar taxa
The hybrid between M. simplex x M.ternata, usually has trifolate leaves which are usually smaller than this species and often darker green like M. simplex, not yellow/green as in M. ternata. Hybrid seedling may be more difficult to separate from this species.
Distribution
Endemic. Kermadec, Three Kings, North and South Islands.
Habitat
Coastal to lowland forest, often favouring margin habitat.
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.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.
