or rarely at first procumbent and rooting at one node and 

 then decumbent. Mr. Arthur Bennett and the Rev. E. S. 

 Marshall, to whom I sent specimens, are unable to refer 

 them to any named variety of this species. 



Vicia Cracca, Linn. — Common on grassy cliffs at the 

 seashore, 40 feet above sea-level, east side of Aith Hope, 

 South Waas, Hoy, 21st July 1913, H. H. Johnston. This 

 common weed of cultivation is almost confined to cultivated 

 land and its borders in Orkney ; but at Aith Hope numerous 

 plants were growing like true natives on the grassy cliffs. 

 Other plants of the same species, however, were growing 

 in an oat-field within 15 yards of the cliffs, and, in my 

 opinion, it is probable that the plants on the cliffs have 

 sprung from seeds derived from plants growing in the 

 cultivated land in the immediate neighbourhood.
