Native. Pascual or Glareal. Found so far north as the 

 county of Ross ; but there the Rev. George Gordon ques- 

 tions its being truly an indigenous plant. The locality 

 given in the Flora of Lanaj-kshire, " at the bottom of the 

 wall called Lover's Leap, at Chatelherault," reads rather 

 suspiciously, when taken in connexion with the absence of 

 the species from the Flora Glottiana. Rather fi-equent in 

 England, on dry and chalky or other calcareous gi-ound. 

 The locality for the Lake province, standing on the 

 authority of Hutchinson, is allowed to pass, but should be 

 confirmed before frill trust can be given to it.

Alien. It is to be feared that there was no good reason 

 for including this shrub in om- lists of indigenous plants. 

 It is frequently introduced in plantations, as an ornamental 

 shrub for under-giowth ; and keeping well hold of the 

 gi-oiuid by its suckers, it remains and spreads in places
