364 THE FLORA OF ALDERNEY. 



and Sagina maritima. The remainder were very local or 

 scarce : Glaux maritima (extremely fine among rocks above 

 high-water mark in one place) ; Scirpus maritimus (a few roots 

 above high-water mark on the western side ; an interesting 

 species because as yet there is no evidence of its occurrence in 

 Alderney), Rumex crispus, Lycopsis arvensis, Crithmum 

 maritimvm, Myosotis arvensis, Atriplex hastata, and in rock 

 crevices on the north side two or three roots of Lastrea 

 Jilix-mas. 



These seventeen plants compose the entire flora of 

 Burhou, so far as I could discover. Possibly in a less dry 

 season a few others would have been added. It is interesting 

 to compare this meagre list with that of Lihou Island on 

 the west coast of Guernsey, the two islands being roughly 

 speaking about the same size. As many as 86 flowering 

 plants and 4 ferns have been found on Lihou, or more 

 than five times as many as on Burhou ; but then the former 

 is very much closer to the main island, and seeds would 

 easily be blown across.

 and fern-allies are enumerated.
