The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.
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.

Shrub with many untidy erect flattened leafless greenish twigs. Twigs 2-4mm wide, smooth. Flowers pink, pea-like, in short spikes. Fruit a flattened papery dry pod containing 2-3 hard mottled seeds and which does not split open.
Endemic. New Zealand: South Island (Marlborough) - south 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 7 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 8.0–28.0 × 2.8–5.2 mm, linear, laterally compressed, strongly constricted between the seeds, the seed outline not visible through the dry fruit wall, and the lower filaments are usually absent on mature fruits, indehiscent; beak up to 2.5 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 are superficially very similar species. They 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.
November – January
January – December
Seeds are possibly dispersed by wind and granivory (Thorsen et al., 2009).
Easy from fresh seed. Semi hardwood cuttings can be struck with difficulty. An excellent species for a steep, free draining bank, cliff face 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.
