120 ENGLISH BOTANY. 



Teibe II.— CHELONE^. 



Corolla tubular, more or less bilabiate, not spurred or saccate 

 at the base ; upper lip covering the others in bud. Stamens 4, 

 didynamous, with the rudiment of a fifth which bears no anther. 

 Inflorescence compound, primarily indefinite, and secondarily 

 definite. Leaves, or at least the lower ones, opposite, rarely 

 verticillate. 



GENUS II.S OROPHULARIA. Toumef. 



Calyx 5-partite or 5-cleft. Corolla tubular, sub-bilabiate ; 

 tube sub-globular or urceolate ; limb with the upper lip the 

 largest, 2-lobed, the lower with 3 short flat lobes, of which the 

 lateral ones are erect and the lower one spreading or reflexed. 

 Stamens 4, didynamous, generally with a fifth reduced to a flattened 

 filament terminating in a free scale-like appendage at the base of 

 the upper lip, sometimes absent. Anthers transverse, with the 

 lobes confluent, so as to be 1-celled. Stigma capitate, entire. 

 Capsule generally conical, acute, opening septicidally and septi- 

 fragally by 2 valves. Seeds very numerous, minute. 



Herbs, with the lower leaves opposite. Plowers rather small, 

 lurid purple, green, yellow, or reddish, in axillary cymes arranged 

 so as to form a slender panicle. 



The name of this genus of plants is due to the supposed efficacy of the species in 

 curing scrofula. 



Section I.— EU-SCEOPHULAEIA. Eeich. 



Corolla-tube not contracted at the throat ; limb irregular, 

 with upper lip longer. Stamens 4, with the rudiment of a fifth, 

 resembling a scale, inserted on the upper side of the corolla-tube.
