 species which had previously been gathered at "Wool as U. vulgarix,

 some fine specimens of U. vulgaris in one of the smallest trenches 

 of a water meadow ; and we had the satisfaction of knowing that 

 Dorset, as well as Hants, possessed all four species. 



It is unusual for these two species, U. vulgaris and U. 

 neglecta, to grow in the same locality. They are made to do so,
