 lowest crenate, the floral bristly-toothed ; lobes of the lower lip of the (whit- 

 ish, yellowish, or bluish) corolla notched. Coast of Maine and Lower Can-

 with small flowers (2 - 3" long), and mostly rounded leaves. Alpine region 

 of N. H., shore of L. Superior, and far northward. 



24. BARTSIA, L. 



Calyx equally 4-cleft. Corolla with upper lip entire and sides not folded 

 back. Otherwise much as Euphrasia. Herbs, with opposite sessile leaves, 

 and subsessile flowers, in the upper axils and in a terminal leafy spike.

 minute tooth on each side below the apex ; lower lip 3-lobed. Stamens 4, 

 under the upper lip ; anthers approximate, hairy, transverse ; the cells equal, 

 pointless. Capsule orbicular, flattened. Seeds many, orbicular, winged. 

 Annual upright herbs, with opposite leaves ; the yellow flowers crowded in a

 serrate, the floral bracts more incised with bristle-tipped teeth ; corolla 6"
