Llaethygen. 

 This alien has been recorded from the neighbourhood of most 

 of the local docks. Oystermouth Castle. Giitch. Phyt. 1842. p. 121. 



1004. Serriola, Linn. Prickly Lettuce. 



This alien established itself on the hurricane beach at Sully 

 about the year 1900, forming a close colony 20 yards long by a yard 

 wide. It still persists there in diminished numbers. A fine example 

 of a " compass plant." 



1005. saligna, Linn. Least Lettuce. 



This alien annual flourished for years on an old marl tip (from 

 Penarth Dock ?), on the roadside near Llandough Railway Platform 

 (1899 to 1906), and was ultimately overcome, I believe, in the 

 struggle for existence by the change in the vegetation of the tip from 

 the " open " to the " closed " formation.
