Class VI. Order I. 125 



is supported by an ovate, mucronated scale. The flowers are 

 alternate, erect, consequently one sided in the horizontal branch- 

 es ; mostly in pairs, but appearing single from one expanding 

 before the other. They grow on a short forked peduncle, 

 which is concealed by several sheathing scales, part of which 

 are common to the two, and part peculiar to the upper one. 

 The calyx is funnel shaped, five angled, the angles ciliate and 

 ending in long acute teeth with sometimes, not always, minute 

 intermediate teeth. The upper part of the calyx is scarious 

 and of a pink colour. Petals spatulate, obtuse, longer than the 

 calyx, pale bluish purple. Stamens inserted in the claws of the 

 petals, anthers heart shaped. Germ small, obovate, with five 

 ascending styles shorter than the stamens. Seed oblong, invest- 

 ed with the persistent calyx. Perennial. 



The root is strongly astringent, and with us is an officinal 

 article of considerable consumption.
