An interesting green form of this grows side by side with the 

 type on Sully Island. At first sight it appears distinct, but if all the 

 plants of the colony are observed carefully, every gradation can be 

 traced between the two extremes. The problem in this case is one 

 in experimental physiology, not in taxonomy. It is probable that 

 this is the plant (or condition) referred to in Ray. Syn. 2nd Edition, 

 p. 161 ; a reference furnished by Mr. A. Bennett to the Hon. Sees.

This plant was collected by the Editor, in flower, at Kenfig, 

 Whitsuntide, 1897, thus fixing its occurrence in this locality three 

 years earlier than the date of its discovery by Marshall and Shoolbred. 

 As I had never collected Limosella before, I regarded it simply as 

 L. aquatica. I failed to collect it in 1898, when it must have been 

 either very scarce or covered by water. In 1905 I found it in great 

 quantity all round the sandy shores of the pool, with the exception of 

 the bay on the North side. It extended from high to low water mark, 

 being most abundant about midway between these. Germination and 

 growth appear to take place under water ; as the level of the water
