178 ENGLISH BOTANY. 



GENUS XII— V EDIOULARIS. Tour?tef. 



Calyx tubular-bellshaped, inflated and bladdery after flowering, 

 with 2 to 5 irregular teeth or lobes, or bilabiate with the upper 

 lip entire or 2-toothed, the lower 3-toothed. Corolla tubular, 

 bilabiate ; upper lip helmet-shaped, much compressed laterally, 

 entire or 2-toothed, or produced into a beak at the apex; lower 

 lip with the lobes sub-erect or spreading, the central lobe com- 

 monly smaller than the others. Stamens 4, didynamous, placed 

 under the upper lip of the corolla ; anthers 2-celled, the lobes not 

 mucronate, except in a single species. Capsule ovoid or lanceolate, 

 laterally compressed, generally falcate or oblique, loculicidally 

 dehiscing by 2 valves. Seeds rather few, large, ovoid-subtrigonous. 



Herbs, with the leaves alternate or verticillate, rarely opposite, 

 generally pinnate or pinnatifid. Elowers in spikes, or more rarely 

 racemes, red or yellow. 



The name of this genus of plants is derived from pediculus, a louse, on account of 

 its being supposed to produce such vermin in sheep.

Stem erect, solitary, usually paniculately branched throughout.

 Elowers in lax spikelike racemes. Calyx in fruit ovate-ovoid, 

 hispid, with 2 lateral lobes, which are again unequally crenate- 

 lobed, crimped and glabrous at the margins and along the 

 sinus. Upper lip of corolla not rostrate, with the margin on each 

 side furnished with a triangular-subulate tooth immediately below 

 the apex, and another blunt tooth about the middle. Capsule 

 ovate-ovoid, curved nearly regularly above from the base to the 

 apex of the beak, which is on a continuation of the middle line of 

 the capsule.
