The extreme dryness of the atmosphere, the want of rain (about 

 3 in.) and the uniform temperature of the low-lying ground in Ascen- 

 sion leads to an absence of soil and the plains are practically adesert; 

 on Green Mountain however the Vegetation steadity increases as one 

 ascends, and at 2000 ft. (rain about 14 ins.) one meets with rieh sub- 

 tropical Vegetation, passing gradually into a temperate type, while 

 the exposed top is covered with grassland. In the plains Vegetation 

 is very scanty and is chiefl^^ represented by the indigenous Portidaca 

 oleracea and Setaria verticiUata (introduced) ; Euphorbia origanoides 

 w^as also observed. Several introduced weeds appear to get on in 

 spite of the adverse conditions (e. g. Vinca rosea , Ricinus coynmunis). 

 The author concludes with a list of Cryptogams found on the island, 

 all of which came from the subtropical zone on Green Mountain.
