 growing on rath at Drumcormick at foot of Slievegallion ; 

 S.A.S. 



'WEZSSZA Ehrhart. (Ulota Bridel). 



[W. Drummondii HooTcer. 



As the tuft, so named, found in Colin Glen in 1869 by S.A.S. is too 

 far advanced to be entirely satisfactory, and as there has been no con- 

 firmation of the record, it is better to leave this species out of our lists 

 until re-found, and in a more satisfactory condition.]

4. "W. vittata (Mitt.) Braith. (Ulota calvescens Wils.),

* As regards this and the succeeding species, with its variety many 

 other localities could have been enumerated, but no stations have been 

 given except such as have yielded mature and Scttisfactory specimens. 

 These have been confirmed by Mr. Holt, and the records though meagre 

 are reliable. Ulota intermedia is scarcely distinguishable even as a variety.
