that affect a drier climate than that of the Andamans ; such species 
have been distinguished by an (*) :— 
2. Such as might he expected to hold their oivn in the struggle for 
existence should the Settlement happen to be abandoned—a class the 
precise limits of which cannot be laid down with certainty; this is the 
class not marked (*) and at the same time not noted as occurring spon¬ 
taneously ; it is moreover from this that the next class is recruited ; 
3. Such as are naturalized in the Andamans noiv —the species for 
which there was evidence either in 1866 or 1890 that spontaneous 
appearance has actually commenced. 
The two former classes do not require further consideration ; taken 
in detail we find that of the last class 14 species were naturalized prior 
to 1866. These were :— 
Impatiens Balsamina. 
Clitoria Ternatea. 
Cajanus indiciis. 
Carica Papaya. 
Vinca rosea. 
Ipomoea Quamoclit. 
Solanum Melongena. 
Lantana cawara. 
Stachytarpheta indica. 
Ocimum sanctum. 
Oomphrena glohosa. 
Ganna indica. 
Cocos nucifera. 
Cynodon Pactylon. 
Before 1889 14 other species, that had been introduced prior to 1866 
but had not at that date become naturalised, had begun to appear spon¬ 
taneously. These were :— 
Bixa Orellana. 
Gossypium harhadense. 
Moringa pterygosperma. 
Trichosanthes cucumerina. 
Luffa cegyptiaca. 
Zinnia elegans. 
Tagetes, sp. 
Capsicum minimum. 
Batura fastuosa. 
Vitex trifolia. 
Mirahilis Jalapa. 
Bicinus communis. 
Gasuaria equisetifolia. 
Goix Lachryma. 
At the same time 9 other species not present in the Andamans at 
all in 1866 were nevertheless appearing spontaneously in 1890. These 
were :— 
Phaseohis trilohus. Ipomoea coccinea. 
Bauhinia acuminata. Torenia, sp. 
Pithecolohium dulce. Thunbergia alata. 
P. Saman. Beeringia celosiodes. 
Colocasia antiquorum. 
So that in 1890 there were in the Andamans no fewer than 37 
species occurring spontaneously that had originally been intentionally 
introduced, as against 14 species of this kind in 1866. 
It is necessary to note further that one species, Zea Mays, which
