of the drought. The plants are very much exposed to 

 the terrific hurricanes which occasionally devastate the 

 Mauritius group of islands. It is not, therefore, to be 

 wondered at that I nowhere saw any trees exceeding 20 

 feet in height, although Sir H. Barkly writes that he saw 

 plants of Latania Loddigesii, Mart., 40—50 feet high in 

 one of the sheltered ravines not visited by me. This palm 

 and the Fandanus Vandermcerschi i , Balf. fil., are the two 

 most widely distributed trees on the island, extending from 

 the seashore upwards to near the simimit of the hill. 

 The other two species of palms, the Hi/ojihorhc amaricaidis. 

 Mart., and Didyosperma album, "Wendl., were not so abun- 

 dant on the lower slopes of the hill near the sea as the two 

 former trees. The dicotyledonous trees and shrubs formed 

 a small wood on the south side of the hill 450—550 feet 

 above sea-level, and it was in this wood only where I 

 found the Trichosandra horhonica, Dene. Although four- 

 teen species of Cryptogams are recorded, they were by no 

 means abundant in number, and most of them would have 

 been passed over by me unobserved if I had not kept a 

 careful look-out for them. 



The remainder of my paper contains a complete list of 

 all the plants recorded from Eound Island by myself and 

 others. I have followed the nomenclature of Baker's 

 " Flora of Mauritius and the Seychelles," so far as Eound 

 Island species are described in it. The lower Cryptogams 

 were identified by Mr. C. H. Wright of Kew Herbarium, 

 and doubtful plants were referred to Mr. J. G. Baker and 

 Mr. N". E. Brown, of the same institution. 



Under each species I have entered notes of my own, 



taken from living specimens ; and I have also, as far as 



possible, entered in chronological order the difierent names 



under which the other botanists have recorded the plants 



observed, by them.
