Vascular – Native
Dicotyledonous Herbs other than 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. New Zealand: North Island (westerly from about Whanganui south to Paekakariki).
In dune fields where it grows in seasonally damp swales (depressions), occasionally found along the margins of slow flowing tidal streams.
Rhizomatous, mat-forming herb, forming dense patches up to 700 mm diam., or diffuse patches when trailing through other vegetation. Stems 1-2 mm diam. Petiole 3-7(-17) x 0.5-1 mm, distinct from leaf. Leaves dark green, glabrous, alternate, appressed to ground, lamina 3-7 x 3-5 mm, rotund, orbicular, leathery, entire, apex obtuse, base obtuse. Flowers single, arising in leaf axils. Pedicel 3-9 mm, glabrous, green to red-green, erect or spreading; bracts 1.5-2 x 0.7-0.9 mm, lanceolate, falcate, green, erect. Sepals 1-1.4 x 0.7-0.9 mm, narrow-triangular, distal part flushed red, apex subacute. Corolla 7-8 x 8-9 mm, 5 petals fused in proximal part, inner surface white, outer pale red. Petals 3-4 x 1.5-2 mm, lanceolate, falcate. Ovary 1.4-1.6 mm, green, glabrous. Style purple-red, stigma glabrous, orange brown. Stamens 3, orange-brown. Fruit 2-3 x 2-3 mm, ovoid, green. Seeds 1.5 x 1 mm, cream-white, compressed.
Distinguished from the allied S. microphlla and S. radicans by the distinctive, small, rounded to completely orbicular leaves.
December - February
January - May
Easy from the division of whole plants. An excellent ground cover for sunny, well drained or water logged soils.
This species is threatened throughout its range by the spread of faster growing and taller weed species which are rapidly modifying the damp, dune swale and estuarine habitats this species favours.
selliera: After Sellier
rotundifolia: Round leaf; from the Latin rotundus and folium
