34. EUPHRASIA Calyx tubular or campanulate, 4-cleft, and rarely with a fifth smaU 

 posterior obe Corolla with dilated throat; upper lip erect, barely concave, 2-lobed, 

 and the sides folded back ; lower larger, 3-lobed, spreading; its lobes obtuse or emargi-

35 BART SI A. Calyx equally 4-cleft. Corolla with upper Up entire and sides not folded 

 back. Seeds sulcate and with salient or alate ribs. Otiierwise much as Euphrasia. 



36. PEDICULARIS. Calyx various, cleft anteriorly and sometimes posteriorly. Corolla 

 with cylindraceous tube and narrow throat, strongly bilabiate; upper lip (galea) com- 

 pressed laterally, fornicate or conduplicate ; lower erect at base, 2-cristate above, 3-lobed ; 

 the lobes spreading or reflexed, the middle one smaller. Anthers transverse,' approxi- 

 mate in pairs. Capsule compressed and often oblique or falcate, rostrate. Seeds nu- 

 merous, various. Leaves mainly alternate or verticillate. 



37. RHINANTHUS. Calyx ventricose-compressed, 4-toothed, inflated in fruit. Corolla 

 with cylindraceous tube ; galeate upper lip ovate, obtuse, compressed, entire at the apex, 

 but with a minute tooth on each side below it ; lower lip shorter, with 3 spreading 

 lobes. Anthers approximate in pairs, transverse, pilose, niuticous. Capsule orbicular, 

 compressed. Seeds few in each cell, orbicular, wing-margined. Leaves opposite. 



* * Ovules only two in each cell, one sessile and ascending, the other stipitate and later- 

 ally attached : flowers ebracteolate : leaves opposite : flowers in our species scattered. 



38. MELAMPYRUM. Calyx campanulate or short-tubular, 4-toothed ; the teeth usually 

 setaceous-acuminate, the posterior larger. Corolla with cylindraceous tube, enlarging at 

 throat : galeate upper lip erect, compressed, obtuse, and with narrow replicate margins or 

 a tooth to each ; lower rather longer, erect-spreading, biconvex below, 3-lobed at apex. 

 Stamens 4: anthers approximate in pairs, nearly vertical; the cells equal and parallel, 

 mucronulate at base. Capsule compressed, oblique or falcate : cells 1-2-seeded. Seeds 

 smooth, strophiolate.
