considered as anything but suggestions. We shall give characters 

 of new genera and species, with indications of their affinities ; 

 and we shall in some cases give monographs of imperfectly 

 known genera. The localities will always be fully given, in ac- 

 cordance with the plan proposed in the * Flora Indica/ and illus- 

 trated in the map of botanical provinces appended to that work. 

 Following the habitats will be a brief guide to the extra-Indian dis- 

 tribution of the species.

 of Dicotyledonous plants. Their title to rank high in that series

Of the StylidiecB and Goodenoviece there are very few represent- 



dia. though the former order reaches its northern 



western 



and as far west as Ceylon, and we believe also Orissa -, for though 

 we have seen no specimens, a species is reported by Griffith to 

 have been found in that country. Of the three Indian Stylidiew, 

 none are the same as JS'ew Holland species ; but one, the Stylidiufn

Hitherto it 



has been detected in no part of India except Ceylon, but it is so 



very nearly allied to the S. Kunthii 



Chittagong and Silhet, that it may prove to be a variety of that 

 plant. 



The Ooodenoviece are represented by two very widely distributed 

 and variable littoral species : one of these appears to be the 

 Sccevola Plumieri of the West Indies, and is also foimd on both 

 coasts of tropical Africa and in the Galapagos Islands ; the other 

 is also a Mauritius and Madagascar species, but has a wider 

 eastern distribution than S. Plumieri^ being spread over the Ma- 

 layan islands, and the tropical coasts of Australia and Polynesia ; 

 it has many jiames, and is the ^S^. KcenigU, Vahl, of which S- se-
