The species and genera of course are not arranged in 
exact systematic order in this double list ; the positions in 
the actual lists are indicated by the numbers prefixed to 
the names. 
Finally, it may be again remarked that the above grouping 
of the Indo-Ceylonese Podostemaceæ is a tentative and 
preliminary one only, to clear the ground for the morpho- 
logical paper to follow. It is based on an insufficient 
knowledge of these very difficult and variable plants. It is, 
however, I venture to think, a nearer approach to the 
natural classification of these plants than any previous list, 
and it clears away many of the errors and confusions of 
preceding work, though doubtless in itself both incorrect 
and incomplete. It will at least form a basis for further 
work, which is very greatly to be desired, and it is to be 
hoped that botanists who have the opportunity of studying
