Each country has a Violet peculiar to itself, with another that is 
found in them both. Both places possess about half a dozen 
species of Hieocarpee each, but only one is held in common ; 
and the same is the case with the Order to which the Tea 
belongs—Terustrémiacee. The genus Impatiens, that to which 
the garden Balsam is referable, affords one of the strongest 
arguments in favour of the fact I am now illustrating ; for while 
each country contains upwards of twenty species, certainly not 
more than three are common to both, and none of the other 
Ceylon species are known to exist elsewhere. Of Rosacee we 
find that the Neelgherry range has only three species of Rubus, 
while there are no less than eight found on the mountains of 
Ceylon, three of which are peculiar to them. Both countries have 
an Alchemilla in common; while the Agrimony of Ceylon does 
not exist on the Neelgherries, but is found abundantly on the 
Himalaya range; and I have lately described a new species of 
Poterium from Adam’s Peak, the only one which has hitherto 
been met with in India. Two species of Potentilla grow in 
Ceylon, and three on the Neelgherries, one only being seen in 
both countries. A comparison of this kind might be extended 
to a great length; but enough has already been shown to prove 
that while the Flora of the central part of the Island has more 
affinity with that of the Neelgherries than with any other part of 
the world, yet it must have had a creation of its own, nearly 
allied, indeed, to the other in forms, but very distinct in indi- 
viduals. 
Although many of the genera found in the upland regions of 
Ceylon are common in Europe, none of the Ceylon species are 
identical with European ones. Indeed, there is not to be found 
growing really wild in the Island, a single species exactly the 
same as any European one. A few, however, have become 
more or less naturalized, having been introduced along with 
garden and other seeds. They are the common Sow-thistle 
(Sonchus oleraceus), the common Chick-weed (Stel/aria media), 
the Mouse-ear Chick-weed (Cerastium vulgatum), the Corn Spurrey 
(Spergula arvensis), and the annual Meadow-grass (Poa annua). 
All these, with the exception of the first, which is much more 
general, are nearly confined to the plain of Newera-Ellia. In 
all countries, introduced plants, which find a congenial soil and 
climate, and which produce their seeds in profusion, of a nature 
to be easily blown or carried about from place to place, are 
sure to naturalize themselves; and often in the course of a few 
years they cannot be distinguished from the really original 
denizens of the clime. Besides those from Europe, just enume-
