A very unpleasant feature in the Cambridgeshire flora is the 

 large number of extinctions. Except Middlesex, I know_ of no 

 county in which so many are to be recorded. In the following list 

 there are doubtless included some species which will be re-discovered, 

 but the majority are only too surely extinct ; and the probability 

 is that it will be augmented by several of the Gamlmgay plants 

 mentioned below : —

Hall Wood, Wood Ditton, had ceased to be a wood at the time the 

 Flora appeared, the site being under cultivation. It was the only 

 Cambridgeshire locality for Vicia sylvatica, Carex strigosa, C. axillaris, 

 and Lysimachia nemorum. I hesitate to call the latter an extinction, 

 but it has not yet been recorded from any other stations, though 

 careful search has been made. 



At Gamlingay, in the extreme west of the county, and on the 

 Lower Greensand, there was formerly an extensive heath containing 

 some very productive bogs. In 1860 the bogs had been drained, 

 and the greater part of the heath enclosed. Now the bog-plants 

 have entirely disappeared, and there is none of the original open heath
