Euphrasia.] All exceedingly variable plant, best distinguished from the two following by the different habit, much larger flowers and usually longer peduncles.

4. E. Cockayniana, Petrie in Trans. N.Z. Inst. xxvi. (1894) 269.—Annual. Stems slender, erect, 2–5 in. high, sparingly branched from the base; branches ascending, more or less clothed with short crisp glandular pubescence. Leaves in remote opposite pairs, ⅕–⅓ in. long, ovate or rhomboid-ovate, subacute, cuneate at the base, furnished with 2–3 rather large teeth on each side, both surfaces more or less glandular-pubescent, margins reflexed. Flowers few towards the tips of the branches, sessile or very shortly peduncled, nearly ½ in. long, bright-yellow. Calyx oblongcampanulate, 4-lobed to the middle, lobes subacute. Corolla-tube longer than the calyx; upper lip 2-lobed, lobes entire; lower lip 3-lobed, lobes emarginate. Capsule broadly oblong, included in the enlarged calyx, glabrous or nearly so.—E. Berggreni, ''Wettst. Monog. Euphr.'' 265, f. 4, 5.

5. E. zealandica, ''Wettst. Monog. Euphr.'' 264, t. vi. f. 430–435, and t. xiv. f. 10.—Annual. Stems slender, erect, 1–4 in. high, much or sparingly branched from the base, or in depauperated specimens simple, more or less bifariously pubescent with short crisp white hairs; branches spreading or ascending, sometimes prostrate. Leaves in distant opposite pairs, sessile, ⅙–⅓ in. long, ovate, obtuse or subacute, cuneate at the base, furnished with 2–4 rather large teeth on each side, both surfaces glandular-pubescent, margins reflexed. Flowers few towards the tips of the branches, sessile or very shortly pedicelled, ¼–⅓ in. long, white; peduncles elongating in fruit. Calyx oblong-campanulate, 4-lobed; lobes usually shorter than the tube. Corolla-tube scarcely longer than the calyx; upper lip short, arched, 2-lobed; lower lip 3-lobed; all the lobes entire. Capsule broad, almost orbicular, scarcely exceeding the enlarged calyx; seeds several in each cell.—E. antarctica, ''Hook. f. Fl. Nov. Zel. i. 199; Handb. N.Z. Fl. 220 (not of Benth.)''. E. pygmæa, Col. in Trans. N.Z. Inst. xxxi. (1889) 279.

Ruahine Mountains, ''Colenso! Tryon! Olsen! Upper Wairarapa, Buchanan.'' Not uncommon in mountain districts throughout. 2000–6000 ft. December–March.

Distinguished from E. revoluta by the different habit, much more conspicuously toothed leaves, and much smaller flowers; from E. Cockayniana by
