PREFACE. IX 



closure of the Exhibition, while he was acting as Registrar of 

 the High Court, Allahabad, he enquired several times about 

 the progress in printing of the present work, more especially of 

 the plates, thus showing his interest in this publication. 



Over 300 drawings were copied in about five months. 

 Professor Bhim Chandra Chatterji had little time to compare 

 the copies with the originals and was, therefore, unable to vouch 

 for their accuracy. Details of several drawings, especially those 

 made from type specimens, had to be completed. So in December 

 1911 I went down to Calcutta and compared the copies of the 

 drawings with the originals. Owing to pressure of work at 

 Allahabad, 1 could not prolong my stay in Calcutta. So several 

 plates were left at Shibpur for details to be filled in. Colonel 

 Gage, I.M.S., obliged me by getting this done. In his letter 

 dated 29th March 1912, in returning the drawings he wrote :--- 



" I return herewith the drawings you sent for filling in the details of the 

 dissections. They have been gone over by Mr. Ramaswamy and checked in 

 every case. It has not always been possible to get precise dissections 

 from the Herbarium specimens, as in the case where there is one specimen 

 we cannot afford to dissect it. 1 trust however what has been done will 

 prove to your satisfaction." 



He has placed us under deep obligation by permitting us to 

 copy and publish some or! the original drawings by Roxburgh 

 preserved in the Herbarium in the Royal Botanical Garden 

 Shibpur, and to reproduce some of the illustrations given in the 

 Annals of it, and also to have drawings made from the type 

 specimens in that Herbarium, of some of the plants not to be 

 found in publications kept in the library of that institution. 



Our thanks are due to Mr. R. S. Hole, F.C.H., F.L.S., I.F.S., 

 Forest Botanist of Dehra Dun, for his kind permission to copy 

 and publish some of the original drawings of plants prepared 

 by Mr. J. F. Duthie, B.A., F.L.S., late Director of Botanic 

 Survey, Northern India. 



We are thankful to the publishers of Curtis's Botanical Maga- 

 zine and of Bentley and Trimen's Medicinal Plants for permis- 

 sion to copy some of the illustrations from their publications ; as 

 also to the Government of the United Provinces of Agra and 

 Oudh for allowing us to copy a few illustrations from the Field
