Myosotis concinna Myosotis concinna flowers Conservation status Naturally Uncommon (NZ TCS)[1] Scientific classification Kingdom: Plantae Clade: Embryophytes Clade: Tracheophytes Clade: Spermatophytes Clade: Angiosperms Clade: Eudicots Clade: Asterids Order: Boraginales Family: Boraginaceae Genus: Myosotis Species: M. concinna Binomial name Myosotis concinna Cheeseman, 1885[2]

***Myosotis concinna*** is a species of [flowering plant](/source/Flowering_plant) in the [family](/source/Family_(taxonomy)) Boraginaceae, [endemic](/source/Endemic_species) to the [South Island](/source/South_Island) of [New Zealand](/source/New_Zealand). [Thomas Cheeseman](/source/Thomas_Cheeseman) described the species in 1885. Plants of this species of [forget-me-not](/source/Forget-me-nots) are large, [perennial](/source/Perennial_plant) rosettes which form loose tufts or clumps, with ebracteate, erect inflorescences, and yellow corollas.

## Taxonomy and etymology

*Myosotis concinna* is in the plant family [Boraginaceae](/source/Boraginaceae) and was described in 1885 by [Thomas Cheeseman](/source/Thomas_Cheeseman).[3][4][5][2]

*Myosotis concinna* is morphologically similar to two other ebracteate-erect species, the northern South Island endemic *[M. brockiei](/source/Myosotis_brockiei),* and the Australian endemic *[M. exarrhena](/source/Myosotis_exarrhena).* *M. concinna* can be distinguished from *M. brockiei* by its yellow corollas (vs. white in *M. brockiei*), hairs appressed (vs. erect) on the margins, and hairs parallel to the mid vein on the upper and lower surfaces of the leaf (vs. oblique or perpendicular).[5]

The lectotype specimen of *Myosotis concinna* was collected by Thomas Cheeseman from [Mt Owen](/source/Mount_Owen_(New_Zealand)), Western Nelson and is lodged at the [Auckland War Memorial Museum](/source/Auckland_War_Memorial_Museum) Herbarium (AK 7549).[6][5] There is also an isolectotype at the [Museum of New Zealand Te Papa Tongarewa](/source/Museum_of_New_Zealand_Te_Papa_Tongarewa) (WELT SP002360).[5][7]

The specific epithet, *concinna*, is derived from the Latin *concinnus* meaning elegant, pretty or neat.[5]

## Phylogeny

*Myosotis concinna* was shown to be a part of the [monophyletic](/source/Monophyletic) southern hemisphere lineage of *Myosotis* in [phylogenetic](/source/Phylogenetics) analyses of standard DNA sequencing markers ([nuclear ribosomal DNA](/source/Ribosomal_DNA) and [chloroplast DNA](/source/Chloroplast_DNA) regions).[8] Within the southern hemisphere lineage, species relationships, including those of the sole individual sequenced of *M. concinna,* were not well resolved.[8]

## Description

*Myosotis concinna* plants are single rosettes that often grow together to form loose tufts or clumps. The rosette leaves have [petioles](/source/Petiole_(botany)) 5–48 mm long. The rosette leaf blades are 16–59 mm long by 4–15 mm wide (length: width ratio 2.2–6.2: 1), usually lanceolate or narrowly lanceolate, usually widest at or above the middle, with an [acute](/source/Acute_(botany)) apex. The upper surface of the leaf are densely covered in mostly flexuous, appressed to patent, antrorse (forward-facing) hairs that are usually oriented parallel to the mid vein. The hairs on the edge of the leaves are similar but always appressed, and the hairs on the underside of the leaf are similar but mostly retrorse (backward-facing). Each rosette has 1–4 erect, branched, ebracteate [inflorescences](/source/Inflorescence) that are up to 300 mm long and are bifurcating in a forked 'V' shape at the tips. The cauline leaves are similar to the rosette leaves but smaller, and decrease in size toward the tip. Each inflorescence has up to 40 flowers, each borne on a [pedicel](/source/Pedicel_(botany)) up to 7 mm long at fruiting, and each without a bract. The calyx is 4–6 mm long at flowering and 6–9 mm long at fruiting, lobed to half or three-quarters its length, and densely covered in antrorse, flexuous or curved, mostly patent hairs, some of which are retrorse. The corolla is yellow (rarely grey blue or purple), up to 16 mm in diameter, with a cylindrical tube, flat petals that are obovate, broadly obovate or very broadly obovate, and small scales alternating with the petals. The anthers are fully exserted above the scales. The four smooth, shiny, medium to dark brown nutlets are 2.0–3.3 mm long by 0.9–1.7 mm wide and narrowly ovoid in shape.[5]

The chromosome number of *M. concinna* is unknown.

The pollen of *M. concinna* is unknown.

It flowers and fruits from November–January, with the main flowering and fruiting period in January.[5]

## Distribution and habitat

*Myosotis concinna* is a [forget-me-not](/source/Forget-me-not) endemic to the Owen Range, Kahurangi National Park, Western Nelson, South Island of New Zealand from 1050 to 1700 m ASL. It is an obligate calcicole found in south-facing marble bluffs and scree in southern beech forest or above treeline.[5]

## Conservation status

The species is listed as At Risk - Naturally Uncommon on the most recent assessment (2017-2018) under the [New Zealand Threatened Classification](/source/New_Zealand_Threat_Classification_System) system for plants, with the qualifier "RR" (Range Restricted).[1][5]
