146 FLORA OF ALDEBNEY. 



the cliffs near the Hanging Rock, and S. nodosa rather plenti- 

 fully on the northern slope of Fort Albert, and also on the 

 common at Fort Houmet. I am now able to give the specific 

 name of the doubtful Sparganium which grows in Longy Pond. 

 One specimen fruited in 1902 and proved that the plant is 

 S. ramosum, not S. neglect Km. Linum us it at is si mum and 

 Cannabis satira were growing on a rubbish heap on the road- 

 side on Butes Hill in 1901. These plants are hardly entitled 

 to a place in the Flora, but it is as well to mention their 

 occurrence in case they should ever become naturalised. 

 C. satira is noted in the Flora Sarnica as naturalised in 

 Jersey. The number of Flowering Plants recorded for 

 Alderney now amounts to 512 species. 



An important addition has been made to the record of 

 Seaweeds. From the following list it will be seen that sixty- 

 two species have been added, of which no less than thirty are 

 new to our islands. They were all collected by my wife and 

 myself during the summer of 1901, and were forwarded in a 

 fresh condition to, and identified by, Mr. E. A. Batters, B.A., 

 F.L.S., to whom I desire to express my most grateful acknow- 

 ledgments. This raises the number of Marine Algae recorded 

 for Alderney to 218 species. In the following list those which 

 are new to the Sarnian islands are marked with a star (*). 



A word or two about Burhou. It is fortunate that I 

 carefully catalogued the scanty flora of this curious islet before 

 the cottagers took possession, for although they lived there 

 only about a twelvemonth, the cultivation of potatoes, cabbages, 

 onions, and other vegetables, and the grain used in feeding the 

 pigs and fowls, have been the means of introducing several 

 entirely new colonists which will probably retain their footing 

 for manv a long year. 



On the 13th of August, 1902, I paid a short visit to 

 Burhou, and found the aspect of things very much altered in 

 the immediate neighbourhood of the house. A few feet from 

 the door there was a large clump of nettles ( Urtica dioica), and 

 all round the house Bume.v acetosella was growing in profusion, 

 — mostly seedlings. The grasses were no longer unrepresented, 

 for there was Poa annua in small patches, of which I counted 

 four or five. In many places near the house Solanum nigrum 

 was very conspicuous, in one direction reaching as far as the 

 pebbly beach. With more time at my disposal I am certain I 

 should have discovered other novelties ; but even the few I 

 have mentioned suffice to show how rapidly the native vegeta- 

 tion of an island may be affected by the direct or indirect 

 agency of man.
