Under many of the species I have entered notes of my 

 own, taken from living specimens. 



An asterisk before the name of a species means that the plants of that 

 species are naturalised. The names of planted species are enclosed in 

 brackets, thus [ ]. 



ILE DE LA PASSE. 



He de la Passe is situated at the South Entrance to 

 Grand Port, and it lies three miles north-east of Pointe 

 d'Esny, and the same distance south-west of Old Grand 

 Port, on the main island of Mauritius. The island . is 

 about 200 yards long from east to west, about 150 yards 

 broad at the widest part, and 30 feet above sea-level at 

 the highest part. At the south side of the island there 

 is an overhanging cliff, 15 feet high, against which the 

 ocean surf continually breaks. A considerable part of 

 the surface is covered with the ruins of an old fort ; 

 but the island has not been inhabited for a good many 

 years past. The sheltered parts of the island are fairly 

 well clothed with vegetation, mostly of an herbaceous 

 character, with a less quantity of low shrubby plants. I 

 botanised on He de la Passe on 26th October 1888, and 

 18th March 1890. 



The following table shows the number of species in each 

 of the three divisions of the vegetable kingdom : — 



The 14 native species belong to 11 natural orders, or 

 little more than 1 species to an order on an average. The 

 number of species in the larger orders are Graminese 3, 

 and Portulaceoe 2. Of the 13 native species of Phanero- 

 gams, the following 5 species are not recorded from 

 Mauritius by Baker, viz. : — Sida diffusa, Portulaca psammo- 

 trojjha, Pliyllanthns mauritianus, Fimhristylis ohtusifolia, 

 and Lcpturus repens.
