E. Fonlaensis was first found in Foula amoug heather, at an 

 altitude of 1000-1200 ft. ; it approaches E. latifoUa in habit and is 

 geographically associated with it. Both species occur in the Faroer 

 Islands. It may be distinguished, from E. latifolia by its nearly 

 glabrous leaves, bracts and calyx, the bracts being also smaller 

 and more distant — from E. gracilis by its obtuse and obtuse-toothed 

 bracts, by its larger and broader capsule, — from E. nemorosa by its 

 simple or little-branched stem, its obtuse and obtuse-toothed bracts 

 and longer capsule. As this species has been so lately distinguished, 

 its distribution and the permanence of its characters have not yet 

 been ascertained. Prof. Wettstein has lately referred plants, gathered 

 by Mr. Marshall from several stations in Caithness and Sutherland, 

 to E. Eoulaensis.
