Rather mountainous woods in various places ; not uncommon in 

 Arran, Cumbrce, and both sides of the Clyde. %. 7 8 —Similar 

 in many respects to the last ; for which, perhaps, it is not unfre- 

 quently mistaken : the Jeaves are sometimes as much covered with 

 pellucid dots, so that the only constant mark is in the veins, and even 

 these in the older and lower leaves become frequently opaque. CoroUa 

 often marked with small black dots. In this, as well as in the fol- 

 lowing six species, the capsule is striated at the back, with copious 



slender longitudinal glands.

as well as the calj/x, and even glandular serratures are sometimes to be
