 the peduncles, calyx-segments, and capsule, which are clothed with 

 gland-tipped hairs.

 North of Perthshire, where it was believed to be extinct, until 

 Professor Balfour rediscovered it in 1863.

 or inserted ; filaments free ; anthers often with 2 awns or crests 

 at the base, opening' by 2 pores or chinks at the apex. Pruit a 

 capsule, with 4 cells opening loculicidally by 4 valves breaking 

 away from the central placental column, to which a portion of 

 each dissepiment remains attached, while the remaining portion is

 from the idea that some of the species destroy the stones formed by lithic acid in the 

 human bodv.
