DROSERA. (Sundew.) 



I. D. rotundifolia. L. (Round-leaved Sundew.) 



Bogs and moist heathy ground. 7, 8. 



This curious little plant is to be found in the moist 

 marshy parts of Harrow Weald Common. 



[ D. intermedia. Hayne. (Intermediate Sundew) is 

 mentioned in Flor. Midd. as having been reported in 1793 

 from "Bogs on Ruislip and Harrow Heaths in great 

 abundance " but on questionable authority. The con- 

 struction of the Ruislip Reservoir may likely have destroyed 

 the plant in one of its habitats, and the excavating for gravel 

 on Harrow Weald Common may have destroyed it in the 

 other.]
