IV PREFACE. 



to whom I am the most indebted in this respect are Pro- 

 fessor Henslow, the Eev. W. H. Coleman (one of the authors 

 of the Flora Hertfordiensis), the Eev. W. W. Newbould, Mr 

 S. W. Wanton, M.A., Mr D. Britten and Mr H. Fordham, 

 of Royston, Mr Algernon Peckover and family and Mr J. 

 Balding, of Wisbech, Miss A. M. Barnard, formerly of 

 Odsey, Mr W. Marshall, of Ely, and Mr G. S. Gibson, of

 Collison, late Fellow of St John's College, who transferred it

 assistance by the communication of notes and specimens; 

 indeed without his help I could not have now ventured to 

 offer this book to botanists. The appearance of his initial 

 upon nearly every page will shew the great extent and 

 value of his contributions. Messrs Britten and Fordham 

 have supplied very full lists of the plants found near Roys- 

 ton. Miss Barnard, grand-niece of the late Sir J. E. Smith, 

 sent a catalogue of plants found about Odsey, at the extreme 

 south-western corner of the county. Mr Peckover and 

 members of his family added largely to the Flora of Wis- 

 bech, to which Mr Balding also made a valuable contribu- 

 tion. To Mr Marshall I am indebted for many localities of
