MR. GUSTAV MANN, 
Late Assistant Conservator of Forests, Assam. 
My pear Mr. Many, 
Your name recurs so frequently during a succes- 
sion of years in the BoranicaL Magazinu, as the discoverer 
of interesting and beautiful Tropical African Plants, that 
the dedication to you of a volume of this work is a duty 
and pleasure on the part of your old friend the Editor. 
To this claim must be added the greater one of your 
epoch-marking contribution to Botanical Geography ; for it 
was by means of the admirable collections of plants which 
you made during your arduous and perilous exploration of 
the Cameroons Mountains and Fernando Po, that the 
presence of a Huropean element in the Flora of the 
mountains of Western Tropical Africa was disclosed. 
Believe me, 
Very sincerely yours, 
J. D. HOOKER. 
Tax Camp, SUNNINGDALE. 
Dec. 1st, 1896.
