Herbs - Dicotyledonous composites
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.

Endemic. South Island, easterly from Canterbury to Southland
Coastal to montane (0-500 m a.s.l.) on sand dunes and inland in short tussock grassland, often on limestone talus or loess derived from calcareous rocks, and on or near limestone and schist rock outcrops.
Silvery-grey (battleship grey) prostrate, creeping, perennial herb forming diffuse to dense mats up to 1 m diameter. Stems up to 0.5 mm diameter, filiform, dark brown, wiry and pliant, emitting numerous fine, long, filiform roots at leaf nodes. branches 5-20 (or more) mm long, weakly ascending to spreading, more or less silky-pilose hairy. Leaves openly to closely imbricating on stems and branches, rarely distant (usually on rapidly growing stems), 2-5 x 0.2-1 mm, uniformly silvery-grey to battle-ship grey, linear to linear-spathulate or spathulate, apex obtuse to rounded, both surfaces covered in fine, more or less appressed greyish indumentum, margins involute. Capitula 4-6 mm diameter, florets 10-15, pale cream, more or less funnelform; involucral bracts 3-4-seriate, outer shorter than inner, broadly-ovate, acuminate, inner linear-oblong, scarious, apices obtuse, often dark brown tipped. Cypsela 0.8-0.9 mm long, ribs indistinct with basal rim not thickened, buff brown to grey brown, obovate to obovate-elliptic. Pappus 3-3.2 mm long, caducous, very finely scabrid.
Previously included by Allan (1961, Fl.N.Z.Vol. I, p. 705) within Raoulia apicinigra Kirk (as R. hookeri var. apice-nigra (Kirk) Allan), R. beauverdii differs by its more open rather than compact turf forming growth habit and darker uniformly dark metallic silver (battleship grey) rather than white foliage and also cytologically. R. apicinigra has 2n = 28 chromosomes, R. beauverdii 2n = 56.
October - December
November - February
Easily grown from rooted pieces and fresh seed. Prefers a free draining, sunny situation. In humid climates it does not grow well.
A naturally uncommon sporadically occurring species
raoulia: Named after Étienne Fiacre Louis Raoul (23 July 1815–30 March 1852) who was a French naval surgeon and naturalist. He published a book Choix de plantes de la Nouvelle-Zélande (“Selected plants of New Zealand”) in 1846. The genus was named after him by Joseph Hooker.
