There are only two species of Cryptogams, viz., Squa- 

 maria (?) aud a land Alga, Ghcctomorpha sp., both of which 

 are common. The 1 9 native species belong to 1 5 natural 

 orders, or about 1^ species to an order on an average. 

 The number of species in the larger orders are Gramineie 3, 

 and Portulacese 2. Of the 17 native species of Phanero- 

 gams, the following 4 species are not recorded from 

 Mauritius in Baker's "Flora of Mauritius and the 

 Seychelles," viz. : — Sida diffusa, Porhdaca 'psammotroplia, 

 Phyllanthus mauritianus, and Fimbristylis obtusifolia. 



The 6 species of introduced plants occurred on the 

 sheltered side of the island, in the lee of the lighthouse, 

 where a portion of the ground has been walled in, and an 

 attempt made to form a garden.

 of the island, and at the middle of the island. See remarks 

 on this species, under He de la Passe, in this report. 



Suhiana maritima, Linu. — Baker, Flor, Maur. Seych.,

 he brought the seed of this species from Old Grand Port, 

 Mauritius, and sowed it in He aux Fouquets, in 1887.
