will scarcely attain the next step in the comital estimate, 

 that of 50. It is somewhat remarkable that this species 

 should have been found in the Isle of Skye, and not else- 

 where on the western side of Scotland ; thus leaving a wide 

 space between Lightfoot's locality and the Lake province 

 in England.

Native. Sylvestral. I have seen no specimens of this 

 species from any province northward of the Severn. The 

 four more northerly provinces are reported on authority too 

 good to be rejected, while verification would be highly de- 

 sirable in each case. They include five or six counties ; 

 namely, Nottingham (Flo. Nott.), Derby (Mr. Coke, in 

 B. G.), North Lancashire (Alton, in Jopling's Furness 

 and Cartmell), Westmoreland (Lawson, quoted in E. F.), 

 Perth (D. Don, in Hook. Scot.), Arran (Lightf. Scot.), and 

 Appiu, Argyle (Carmichael, in Hook. Scot.). These more 

 northerly habitats, or some of them, may perhaps belong 

 to E. ensifolia, if the two are really distinct species. For 

 the present, however, I feel obliged to adopt them here 

 on the credit of the authorities cited, and to draw up the 

 formula of distribution in accordance. The locality of 

 Appin verges on the superagrarian zone.
