Lponuea (jlaherriina, Bojer, and PhyUanihus niauritiamis, 

 H. H. Johnston, are the only native species which are not 

 recorded from ]\Iauritius in Baker's " Flora of ]\lauritius 

 and the Seychelles." The former was found in Flat Island 

 by Home in July 1885, and by me in He Vakois in 1889, 

 and in He Marianne in 1890, in all of which islands it is 

 undoubtedly native. The latter is a new endemic species. 



Gymiio&jporia trigyna, Baker, Oldcnlaiulia Sieberi, Baker, 

 and Phyllanthus mcmriticmus, H. H. Johnston, are the only 

 three species I found on He des Aigrettes, which are 

 endemic in the Mauritius group of islands, and not found 

 in any other part of the world. 



The greater number of the 18 species of more or less 

 naturalised plants occurred on the waste ground near the 

 lime-kiln and caretaker's house. Three of the naturalised 

 species, Soplwra tomcniosa, Linn., Ipomcea Nil, Both., and 

 Nicotiana Tcibacum, Linn., are not recorded from Mauritius 

 in Baker's " Flora of ^Mauritius and the Seychelles," pub- 

 lished in 1877. 



With the exception of the waste ground at the north 

 end of the island, the surface is clothed with a dense mass 

 of shrubs, intermingled with climbing plants and a parasite, 

 Cassytlia filiformis, Linn., belonging to the Lauraceae. 



In addition to the plants identified and enumerated in 

 this report, I found one species each of the following genera, 

 viz. Folyscias (?), Diospyros, Ficus (?), Draccciia, and Phyl- 

 lanthus, but as the plants were neither in flower nor fruit, 

 they have not been identified. I also observed among the 

 cultivated plants a species of Cucumis and a garden plant, 

 which have not been identified. I was informed by Mr. A. 

 Daruty de Grandprc' that he had found an orchid on this 

 island, but it was not observed by me. 



As He des Aigrettes is easily accessible, I hope to revisit 

 it at some future time, and further investigate its flora, 

 which will probably yield a considerable number of species 

 additional to those recorded by me in my present report. 



The remainder of my paper contains a complete list of 

 all the native, naturalised, and cultivated plants which 

 were observed and identified by me in the island. I have 

 followed the nomenclature of Baker's " Flora of Mauritius 

 and the Seychelles." Under several of the species I have
