OF INDIA AND CEYLON.

occur on the same plant, and it is by no means difßcult to 
get from one plant in the Bombay Ghats pieces resembling 
the types of L, pulchella and L. longipes respectively. 
These two must therefore be united, and the only question 
left is whether the Indian forms are specifically distinct from 
the Ceylon forms. Enormous labour will be needed to fully 
settle this question, but for the present I have no hesitation 
in uniting them, though, as already mentioned, every locality 
seems to have its own peculiar form. The Indian forms 
agree fairly well among themselves in the following points 
of difference from those of Ceylon : they have a rather longer 
fruiting pedicel, a more obovoid and lighter coloured fruit, 
thinner fruit ribs, and usually rather longer leaves. The 
thallus type of the northern forms is more like that of the 
common Ceylon forms than that of the southern, so that it 
is possible that the two should be separated on geographical 
grounds, but for the present our knowledge is insufficient. 
Four groups of forms are found among the material at my 
disposal.
