The extension of such a calculation to the whole of the 900 square miles 
of South Andaman shows that that island can scarcely contain more than 
600 or 700 species. Travelling, however, from place to place, and taking into 
view the great change of vegetation and the numerous unexpected appearances 
of new forms with which we so frequently meet, the number of really indi¬ 
genous phanerogamic plants may range between 1,500 and 1,800 species. 
A square of 100 feet on the western coast, when carefully taken up, would 
give quite other results from what I have just shown as the result of such an 
investigation in the eastern part. 
Previous botanical collections. 
26. Colonel Kyd, in 1791, introduced from the Andaman Islands (most 
probably from Port Cornwallis) several plants into 
the Botanical Gardens, Calcutta, which were des¬ 
cribed afterwards by Dr. Boxburgh in his Elora Indica. Dr. Heifer, when on 
deputation on these islands, made large botanical collections. He was, how¬ 
ever, unfortunately killed by the aborigines; and his Andamanese collections 
were afterwards mixed up with his Tenasserim plants. The greater part of 
his collections could not, therefore, be embodied in my list. A few plants have 
been gathered by Drs. Playfair and Liebig, most of which are contained in 
the Herbarium of the Boyal Botanical Gardens, Calcutta. More recently (in 
the year 1863, I believe) the Eeverend C. Parish, of Moulmein, visited Port 
Blair and collected plants, but I am unacquainted with his collections. My 
own collections, though far the richest, will probably be found to be very poor 
indeed when the whole of the flora is known. 
27. Annexed Appendix A is a list of the plants known from these 
„ , ,, , . - islands, including the Cocos and Barren Islands. 
Andaman islands hitherto known, with I found it uselul to mention the native names as 
Appendix a. far as j cou id obtain them, and also remarks upon 
the occurrence of the several species, as I am convinced that a bare list does 
not give us the impression which we obtain when. investigating the vegetation 
on the spot. 
It contains also most of the newly acclimatized and most of the cultivated 
plants. 
Appendix C.^ 
Appendix C contains the descriptions of the 
apparently new species gathered by me on these 
islands. 
The Cryptogams (except ferns) are only generally treated here. They 
cannot be determined in India owing to the absence of accurately named 
specimens. 
I have now only further to remark that the species marked before their 
names with an asterisk are introduced ones ; those in small type occur only in 
a cultivated state; the remainder I consider as really indigenous, i . 
originally present before settlement of these islands. 
* Is not taken up in the first edition of this report, and therefore it has been omitted also here. The descriptions 
will probably be published along with other contributions towards a Burmese Flora in a scientific journal.
