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.

Strictly coastal. Usually at the back of salt marshes and estuaries, in permanently damp or soggy, saline mud or silt soils in locations that are periodically flooded during high, spring or King tides. Sometimes in dune swales. Intolerant of much competition from taller plants or faster growing mat-forming species.
Mat-forming, succulent, perennial herb. All parts glabrous. Stems dark green to red-green, prostrate, sometimes ascending at apices, rooting at nodes. Leaves sessile, amplexicaul, c. 2-8 x 1-6 mm, dark green, brown-green to reddish-green, broadly ovate-oblong, entire, punctuate, somewhat succulent. Flowers on short, ascending branches, solitary in leaf axils; pedicels 2-8 mm long, dark green to pinkish-green. Calyx 2-7 mm long, < corolla tube, broadly funneliform; apex truncate, minutely toothed. Corolla 10-15 mm long, distinctly 2-lipped. light purple, mauve, lilac or white, red-spotted with yellow open throat; lower lip bearded; lobes shallow, broader than long. Capsule 6.5 mm long, broadly cylindric.
None - the combination of habitat preference, mat-forming growth form, succulent, glabrous, dark green to red-green stems and foliage, and light purple, mauve, lilac or white flowers mark this species out from the three other introduced and yellow-flowered Erythranthe species present in New Zealand.
September - February
November - May
Easily grown from rooted pieces, stem cuttings and fresh seed. Very beautiful but tends to be short lived. Needs frequent re-potting to maintain itself and should be grown in full sun in a pot kept partially submerged in water.
A widespread, naturally uncommon, biologically sparse species. It is most uncommon in the northern North Island becoming progressively more abundant south of the Waikato, although it is still often absent over large parts of the country. In some parts of its range, particularly metropolitan Auckland, populations have been lost through road realignments (where they cross salt marshes e.g., the upper Waitemata Harbour) or through land reclamation. The spread of the aggressive salt grasses (Spartina spp.) and Carex divisa. is also a risk in some parts of its range. Nevertheless, these range contractions are insufficient nationally to justify an upgrade to one of the three threat categories.
repens: From Latin repere meaning to creep, means creeping

Barker et al. (2012) proposed a new classification for Mimulus in which they segregated off a number of genera, including the erection of a monotypic Thyridia W.P.Barker et Beardsley to cover the Australasian species Mimulus repens R.Br. However, many of the characters which were used to segregate that genus are found also in Peplidium Delile and further the molecular support for the generic splits proposed is weak. Therefore until further research is undertaken it seems wise to retain the existing classification for Mimulus.
