Current conservation status
The threat classification 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) – more information about this can be found on the NZTCS website 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. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Distribution
Endemic. South Island, Matiri Range south to Cragieburn Forest Park.
Habitat
Montane to subalpine boggy and open places.
Features
Slender erect succulent-like annual herb 50-100 mm tall, sparingly branched from base, branches pilose with lax transparent hairs and usually dense long jointed glandular hairs. Leaves sessile, rather distant, 4-12 x 3-10 mm, quadrate-ovate to suborbicular in outline with 2-4 pairs of subacute to acute teeth, cuneate at base, scabrid with stiff appressed hairs, especially on thickened revolute margins, and usually densely pilose with long jointed glandular and smaller non-glandular hairs. Flowers, few or several pairs towards the tips of the branches, sessile or on pedicels up to 4 mm long. Calyx 5-8 mm long (sometimes up to 10 x 6 mm in fruit), pubescent as leaves, subevenly divided 1/3-1/2 way; lobes acute, margins and midribs thickened. Corolla bright yellow, 10-12 mm long; tube approximately equal to or longer than calyx; lobes of lower lip up to 3 mm wide, shallowly emarginate. Anthers golden yellow, margins hairy, awns usually very unequal. Capsule longer than calyx, 5-8 x 4-5 mm, obovate to pyriform, glabrous; seeds 6-8 per locule, 1.5-2 mm. long.
Flowering
December – March (June)
Flower colours
Yellow
Fruiting
January – March
Life cycle
Seeds is dispersed by wind and possibly water and ballistic projection (Thorsen et al., 2009).
Etymology
euphrasia: Eye-medicine
cockayneana: Named after Leonard Cockayne FRS (7 April 1855 - 8 July 1934) who is regarded as New Zealand’s greatest botanist and a founder of modern science in New Zealand
TAXONOMIC NOTES
On the Paparoa Range plants are rather uniformly luxuriant with long glandular hairs abundant and the stiff appressed scabridity obscured or almost absent. At Arthur’s Pass and other localities where it occurs in company with E. zelandica the pubescence is very variable; sometimes the flattened white hairs characteristic of the latter species occur on the leaves and glandular hairs may be absent, the fine stiff pubescence of margins and veins then similar to that of E. cheesemanii. Gradation also in habit and in size and colour of corolla is noted under E. zelandica.
