4 DR. HOOKER AND DR. THOMSON'S PRiECTJRSORES 



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.

"We commence these sketches with the Gamopetalous EpigyncPj 

 from their having been recently under our examination, and not 

 from any considerations connected with their position in the series 

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

 will, however, be considered very strong by those who regard co- 

 hesion and adhesion of the floral whorls, and a great deviation from 

 the typical leaf, in the organs of which these consist, as certain 

 indications of high development in a plant. 



Of the Stylidiece and Goodenoviece there are very few represent- 

 atives in India, though the former order reaches its northern and 

 western limits in that country ; advancing to Silhet in !D^. lat. 25°, 

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

 we have seen no specimens, a species is reported by G-riffith to 

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

 none are the same as New Holland species ; but one, the 8tylidium 

 uliginosum, is certainly also found at Hong Kong. Hitherto it 

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

 very nearly allied to the ^S*. Kunthii of the Malayan Peninsula, 

 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 

 Scwvola Flumieri of the West Indies, and is also found 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. Flumieri, being spread over the Ma- 

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

 it has many names, and is the S. Koenigii, Vahl, of which S. se- 

 ricea, Porst., is only a state, with more copious silky hairs on the
