Gen. Cuar.—Calyz inferior, of one sepal, tubular, cylindrical, ribbed, per- 
manent; the margin in four deep, nearly equal, pointed teeth. Corolla 
of one petal, ringent, open; tube as long as the calyx, cylindrical; upper 
lip slightly concave, with several notches; lower lip spreading, divided 
into three, more or less, unequal, obtuse, cloven, or inversely heart- 
shaped lobes. Filaments thread-shaped, directed towards the upper 
lips. Anthers incumbent, large, of two roundish lobes, pointed at the 
base; the points of the lower anthers elongated into straight, bristly 
spines. Germen, egg-shaped. Style, thread-shaped, as long as the sta- 
mens. Stigma blunt, undivided, Capsule oblong, blunt, compressed, 
emarginate (notched at the summit), of two cells, and two membranous 
valves. Seeds several, very small, elliptical, compressed, furrowed, or 
striated on each side. The four-cleft calyx, spinous anthers, two-celled 
capsule, and furrowed or striated seeds will distinguish this from other 
genera in the same class and order (Bazter). 
Sprc. Cuar.— Leaves egg-shaped, furrowed, sharply toothed. 
Hisrory.—F. Bauhin (Phytop., p. 442) states that, although 
Dalechampius gave the derivation of Euphrasia from the Greek, 
yet there is no notice of this herb in the works of Dioscorides,
