528 REV. R. BARON ON THE 
Tn regard to the genera whose distribution I have been able to 
determine, there are :— 
Common to the three Regions .......... seses 184 
» » Eastern and Central Regions .... 131 
» » Western and Central „, .... 82 
» » Eastern and Western ,, .... 119 
Peculiar to the Eastern Region ............ .... 153 
Not peculiar to E. Region, but occurring in it .... 434 
Total in the Eastern Region .... 587 
Peculiar to the Central Region ...............- 130 
Not peculiar to C. Region, but occurring in it.... 847 
Total in the Central Region .... 477 
Peculiar to the Western Region.......... ...... 115 
Not peculiar to W. Region, but occurring in it.... 335 
Total in the Western Region.... 450 
There are, as shown by one of the preceding tables, 3178 
species of plants whose distribution in the island I have been able 
to make out. There remain to be determined about 1000. 
Some of these occur in the extreme north of the island, both on 
its eastern and western sides, and therefore belong to both the 
Eastern and Western Regions; butas the boundary line between 
the two in this part of the country is more or less arbitrary, I 
have not taken them into account. The names of the parts of the 
island where other plants have been found are sometimes given 
in publications, but, owing to inaccuracy on the part of the 
collectors, or blunders in copying, I have been frequently unable 
to locate them, as, for instance, * Anànlsinàhina bozaba.” What 
part of the island is meant by such a blundering combination of 
letters it is impossible to say. ‘“Chasak mountains” is also 
given in one publication. Possibly this is meant for Ankaratra 
mountains! These localities, when quite unrecognizable, I have 
also omitted. 
Although the figures in the above and the following tables will 
doubtless require alteration when we become acquainted with the 
localities of the remaining plants, and though some of those which 
at present are only known to occur in one of the three Regions
