The following remarks on this table may not be out of place. The 
absence at once from the Andamans and from Ceylon of certain species 
is at first sight good negative evidence of a statement made by Mr. 
Kurz (Z. c. p. 15) concerning the Andamans ;—“ A few Ceylon species 
“ indicate some relationship between the Andamans and that island.” 
But it is unwise to believe that a thing does not exist because it has 
not been seen, and it is, as regards the Andamans at least, no evidence 
because these species have not yet been met with yet that they do not 
occur there. The positive evidence from the species that occurs in 
Ceylon and is very frequent all along the Andamans group (Ipomcea 
denticulata) but that nevertheless is absent from the western or Indian 
shore of the Sea of Bengal is also without value. The curious but 
constant feature as regards its habitat already remarked on, may ex¬ 
plain its absence from the long line of sand-dunes that stretches from 
the Coromandel Coast up to Orissa. At the same time, it must not be 
supposed that Mr, Kurz’s remark has been based on facts that are as 
easily explained as these are.^ 
In order to provide a basis for the computation of the relative value 
of the Arracan, Pegu, and Andaman influences in the composition of 
the Diamond Island flora, it is necessary to tabulate further the facts of 
distribution so far as these three districts alone are concerned. 
* The writer has himself to add an instance quite as striking as any of those 
that were met with by Mr. Kurz. In Novembsr 1889 he collected on Mount 
Harriet in S. Andaman Strongylodon ruber- Yogel, a Polynesian species that has a 
somewhat peculiar distribution in that it also occurs in Ceylon j to the Ceylou 
locality has now to be added that of S. Andaman also.
