This catalogue offers many points worthy of discussion, but which it would be beyond the object 

 and scope of this Essay to discuss. The Indian botanist will recognize the double element, one 

 consisting of a littoral and the other of an inland Flora, the former prevalent over the shores of both 

 Indian peninsulas, the Malay and Philippine islands, and, to a certain extent, the Louisiade and 

 Western Pacific groups ; the other or inland Indian Flora characteristic of the Carnatic, the sandstone 

 table-lands of the western Peninsula of India, and which reappears in the Upper Birma valley, where 

 the climate of this becomes dry for a considerable portion of the year. A list of representative Indian 

 species would have added greatly to its value, as further establishing the close relationship between 

 endemic Floras of central Australia and central India, for it would include many species of the 

 following conspicuous Indian genera which are not enumerated in the foregoing list : —

Another point is the much larger proportion of Monocotyledons than of Dicotyledons ; of the 

 former class fully one-third of all the tropical species are also found in India, of the latter not one-
