ŵ POSTSCRIPT. 
To my most valued friend Dr. Boott, the worthy Secretary of the Linnean Society of London, whose whole life is 
a beautiful comment on the Nulli nocere—plurimum prodesse cuigue, I owe obligations throughout my botanical labours 
in England which it is impossible for me ever to forget or adeguately to acknowledge. 
I cannot close this imperfect tribute to those to whom I am indebted, without particularly expressing my obligation 
to Mr. Gauci for his ever prompt and courteous attention to the engraving of the Plates, during which he has uni- 
formly displayed that readiness to oblige, and that amiable consideration for the feelings of others, which so pecu- 
liarly distinguish him, and without which it would certainly have been impossible for me to complete my work 
within the time originally contemplated: and the same tribute is egually due to Mr. John Clark for his kindness 
in the execution of the colouring. For both of these worthy men and admirable artists I beg to express my sincere 
respect. 
One family of plants has not received from me that attention to which its peculiar interest entitles it, principally 
in conseguence of the early contemplation of a separate work devoted to it by my excellent friends Drs. Hooker and 
Greville, the distinguished authors of the beautiful Icones Filicum. Their Filices Asiaticæ Rariores, which will appear 
as soon as subscribers have been obtained to cover the heavy expense of such a work, may be considered as the com- 
pletion of my own. 
Since the date of the list contained in the Preface, the following distinguished botanists have kindly undertaken the 
monography of several of the remaining genera and families in the Company's Herbarium : 
Mr. BRNTHAM : Cyrtandraceæ, Myriceæ. 
Mr. Brown: Sonerila. : 
Dr. GREVILLE : Geraniaceæ. 
Mr. Hawortu : Portulaceæ, Sedeæ. 
Prof. HensLow: Balsamineæ, Dilleniaceæ, Hippocastaneæ, Stylideæ. 
Prof. Linprey: Antidesmeæ, Aurantiaceæ, Bixineæ, Grossularieæ, Guajacanæ, Halorageæ, Jasmineæ, Olacineze, 
Oleinæ, Podophylleæ, Resedaceæ, Rhizophoreæ, Samydeæ, Santalaceæ, Schizandraceæ. 
Prof. von Martius: Aroideæ, Hydrocharideæ, Scitamineæ. 
Prof. Meisner : Thymeleæ. 
Prof. C. G. Nees von EsENBECK ; Piperaceæ. 
Count Caspar von STERNBERG has already done me the honour to publish the Saxifrageæ in his most excellent 
work; and I am gratefully indebted to my highly esteemed friend Professor LEHMANN for the publication of the 
Hepaticæ. 
A Map, which has been compiled and executed by Mr: J. Arrowsmith, will serve to illustrate the extent of territory 
from which not only the plants figured in this work, but those contained in the Company's Herbarium, have been 
derived. It comprises, besides my own routes, those of other botanists who have travelled in India. I regret not 
having had materials for pointing out those of Roxburgh and König: it is however well known that the former 
resided partly at Samulcotta and partly at the Botanic Garden at Calcutta; and the latter made 
various journeys 
from Tranquebar and Madras to different parts of continental India and its islands. 
Dr. Hamilton’s route across the 
been laid down; but it was impossible to introduce those connected with his 
various statistical surveys of the Bengal provinces, 
southern part of the peninsula has 
a work consisting of fourteen folio manuscript volumes, 
and 
unrivalled for the inexhaustible stores of information it contains. 
The expense attending the Map has rendered it 
I feel it incumbent: upon me to mention. in justice to the Publishers, 
hardly necessary for me tô intimate, that I have had no pecuniary 
to last. 
necessary to omit several Plates; this “e
