tisually not so tall, and the leaves (or at least the outer ones) of 

 the barren shoots are abruptly contracted into the petiole, and acumi- 

 nate at the apex. The blotches on the leaves of the plant in the spe- 

 cimens I have seen are larger, and have a greater tendency to become 

 conHuent. Ihe calyx-teeth are deeper, and the fruiting calyx is more 

 bellshaped. Ihe flowers are very similar, at first rose, then blue, as 

 in 1 . angustifoha, but not nearly so highly coloured ; the corolla is the 

 same m shape, but usually a little larger. The nucules are more 

 acute at the summit, and rather smaller. The hairs m the stem and 

 leaves are stifter, so that the plant is much harsher to the touch I 

 have not seen P. officinalis with the stamens exserted beyond the 

 corolla tube.

 According to the ancient doctrine of signatures, tliis plant had an especial efficacy 

 m diseases of the Inngs ; its spotted leaves being supposed to represent these or^rans, 

 and, therefore, to indicate the direction of its natui-al cm-ative properties. '^
