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.

Rare small tree with untidy, greenish-yellow leafless twigs inhabiting valleys in Marlborough. Twigs oval in cross section, smooth, tending to droop. Flowers small, pink with darker streaks, clustered into conspicuous sprays. Fruit in a 1-4cm long dry flattened pod containing up to 10 hard black mottled seeds.
Endemic. South Island, Marlborough, north of the Awatere fault.
Lowland to montane. A species of alluvial terraces, gorges, cliff faces and steep valley sides.
Leafless, spreading to upright, shrub or small tree up to 5 m tall. Branchlets slender, 120–400 × 1.8–4.0 mm, drooping, green, compressed. Leaves on branchlets reduced to a triangular scale, glabrous, < 0.8 mm long. Inflorescence a raceme, up to 30 mm long, with up to 20 flowers; pedicel 1.0–3.5 mm long, sparsely hairy. Calyx 1.5–2.4 × 1.5–2.4 mm, outer surface sparsely hairy to glabrescent, or glabrous, green; lobes 0.4–0.6 mm long, triangular. Flowers pink with dark pink veins, up to 8 mm long. Standard 7.0–7.5 × 6.3–6.6 mm, obovate, recurved; wings 5.3–7.8 × 1.0–1.7 mm, oblong, shorter than keel; keel 6.6–8.5 × 2.1–3.2 mm. Stamens 6.0–7.5 mm long. Pistil 7.8–8.4 mm long, exserted beyond stamens, ovary glabrous. Pods 10.0–36.0 × 2.5–4.0 mm, linear, laterally compressed, constricted between the seeds, the seed outline often visible through the dry fruit wall, and the lower filaments are usually persistent on mature fruits, indehiscent; beak up to 4 mm long, narrowly triangular, tapering to the persistent style; with up to 10 seeds. Seeds 2.0–3.5 mm long, reniform to reniform-triangular, light green-yellow, buff or orange-brown, often with black mottling.
Carmichaelia carmichaeliae and C. glabrescens have a similar growth habit, branchlets, and flowers. Carmichaelia carmichaeliae differs from C. glabrescens by the pods being weakly constricted between the seeds, the seed outline often visible through the dry fruit wall, and the lower filaments are usually persistent on mature fruits. C. glabrescens pods are shorter and broader, there are no constrictions between seeds, the seed outline is not visible through the fruit wall, and the lower filaments are usually absent from mature fruits. C. glabrescens grows south of the Awatere fault.
November to January
January to December
Seeds are possibly dispersed by wind and granivory (Thorsen et al., 2009).
Easy from fresh seed. Semi hardwod cuttings can be struck with difficulty. An excellent species for a steep, free draining bank, cliffface or rock wall. Does well in any soil provided it is free draining. This species should be planted in full sun. It is intolerant of heavy shade and humidity.
Threatened by aerial spraying for gorse (Ulex europaeus L.) and broom (Cytisus scoparius (L.) Link), browsing animals, (especially goats, cattle, possums and deer) and habitat loss through competition from weeds.
