clxxxviii Appendix C. 
graphic Index of British and Irish Botanists/ Others I include with 
the view of rescuing their names and disinterested labours from total 
oblivion, a few from their writer’s great learning or distinction. 
(2) Individuals who have materially aided my father otherwise than 
strictly scientifically in his various efforts for the advancement of 
botany, and especially by the development of Kew as a National 
Establishment. Such were many merchants and manufacturers, who 
urged their foreign agents or correspondents to respond to my 
father’s requests for information and specimens. Many of them 
transmitted freight free all consignments of specimens to and from 
the Royal Gardens, Kew. 
(3) Government officials, who, to use a common expression, 4 went 
out of their way’ to carry out my father’s views and wishes. It is 
impossible to exaggerate the services rendered officially or semi- 
officially by the Secretaries and other employes of the Admiralty 
(especially its Hydrographers), the Foreign and Colonial Offices, the 
Board of Trade, the East India Company and the Hudson’s Bay 
Company, and by the Governors and Secretaries of our Colonies all 
over the globe. 
(4) Directors and owners of Horticultural Establishments, Imperial, 
Royal and Commercial, including many of the leading Nurserymen of 
Great Britain and Ireland, France, Belgium, Holland and Germany, 
who by gifts and exchanges lavishly enriched the Gardens of Kew. 
I regret that it is impossible to give more information regarding 
the 1,612 individuals catalogued, than their names, the number of their 
letters which have been preserved (more than 21,500), the years over 
which their correspondence extended, and very vaguely and unsyste- 
matically the localities where they resided, or from which they wrote. 
In very many instances they wrote from many localities, in which 
case I have selected a prominent one. 
Of my father’s letters to these correspondents I have seen com- 
paratively few. There are preserved in the Kew Herbarium those 
addressed to Mr. Bentham, 610 (1825 to 1865), to Sir John Richard- 
son, 87 (1819-1843), to Dr. Harvey, 247 (1832-1868), and some 
others. I have those addressed to Mr. Dawson Turner, 728 (1805- 
1851), and Mr. Turner’s addressed to Mr. Borrer, 135 (1806-1819). 
To the last two series I am indebted for many particulars of the life 
of my father, who, except sometimes when travelling, kept no diary 
or journal of any kind.
