Euphrasia arguta is an erect, semi-parasitic annual herb growing between 20-45 cm in height. Branches are densely hairy with recurved stiff, non-glandular hairs. The plant has 18-30 pairs of leaves along each stem. Leaves are in pairs opposite to each other, with adjacent pairs arranged at right angles. Individual leaves have no stalks, are ovate to elliptical in shape and 7-15 mm in length, 3.5-13 mm wide, with two to four pairs of long, slender ‘tooth-like’ projections. The leaf surface can be either rough or smooth, and with or without deeply lobed margins.
