from 500 feet to 2500 on Mount Brandon. It has never been 

 found in fruit. Dr. Spruce, in his work above quoted at 

 p. 440, writes: — "I cannot doubt that the Jung. cuneifoUa., 

 Hook., Brit. Jung., t. 64, hitherto known only from sterile 

 specimens, is a true Clasmatocolea. Specimens gathered a few 

 years ago on Mount Brandon by McArdle are so like the 

 arcuate barren shoots of CI. frageUima that until I compared 

 them closely I thought them the same species. The Irish 

 plant (like the Andine) has both entire and bifid under-leaves 

 (stipules), and was correctly so described by Nees from original 

 specimens of Miss Hutchins, although Hooker's figui'e 1 c. and 

 the E. Bot. figure (t. 2700) show only bifid underleaves."
