well." This species is common in Orkney, but I exhibit a 

 specimen for comparison with E. UNIGLUMIS, SchuUes, which 

 is rare in Orkney. 



Eleocharis uxiglumis, SchuUes (name continued by 

 Arthur Bennett). — Water-channel in a marsh near the 

 sea 5 feet above sea-level, Myres Bay. South Waas, Hoy, 

 19th July 1913, H. H. Johnston. Native. Common in 

 the marsh. Lowest glume almost surrounding the spike. 

 Remark by Mr. Arthur Bennett : — " Nice specimen showing 

 well, especially the younger stems, the character of uxi- 

 glumis." This species was first recorded from Orkney by 

 the late Dr. J. T. I. B. Boswell. who found it in the Fidge, 

 Swanbister, < >rphh\ Mainland, where the low-lying marshy 

 ground is liable to be flooded with sea water during high 

 spring tides. See •Scot. Nat.," No. ii.. new series. October 

 1883, p. 72. The Rev. E. S. Marshall also records it as 

 ' plentiful on the south side of Loch Stenness." Stenness, 

 Mainland, in which loch the water is brackish.
