Stems simple or branched, to 9(–12) cm; branches 1–3 pairs, ascending, from basal cauline nodes; cauline internode lengths 1–2 times subtending leaves. Leaves: blade orbiculate to triangular-ovate or oval, 2–4(–6) mm, margins crenate to incised-crenate, teeth 1–4 pairs, apices obtuse to subacute. Inflorescences sparsely spicate, not 4-angled, beginning at node 4–6, proximal internode lengths 1–1.5 times bracts; bracts green or suffused with purple, as broad as leaves, ovate or oval, length not more than 2 times width, 2–4 mm, base round, surfaces coarsely, densely hirsute with short-eglandular hairs, teeth 3–5 pairs, as long as wide, apices obtuse to acute, sinuses between teeth acute. Flowers: calyx lobes straight, apex acute; corolla white or cream, rarely purple, adaxial lip lilac or purple, 2.5–4.5 mm, lips +/- equal. Capsules oval to oblong or obovate, 2.5–4 mm, apex retuse to emarginate.


Phenology: Flowering mid summer–fall.
Habitat: Dry, grassy habitats on sandstone or limestone barrens, rocks, ledges, sandy beaches.
Elevation: 0–300 m.

Distribution

N.B., Nfld. and Labr. (Nfld.), N.S., Ont., P.E.I., Maine.

Discussion

Euphrasia farlowii differs from E. randii by its compact growth with condensed (versus elongated) cauline internodes and growth on calcareous soils versus non-calcareous soils (G. Gussarova 2017).
