The Pomegranates, Figs, and Bananas, which are planted 



about the houses, together with the bright green of the Arums, 



gave a singular charm to this district. Of these sixty-eight 



species, seventeen extended as far as the region of the Vine, 



and only two of them were met with again at a height of 



5300 feet. 



2. Region of the Vine. 



The cultivation of the Vine may indeed be said to com- 

 mence at the sea shore ; but the Cactus does not accompany 

 it above 630 feet. The Vine ascends to an elevation equal to 

 2030 feet, but higher than that the fruit will not ripen. In 

 this region the Arum, Cane, Mulberry, &c. Potatoes, Corn, 

 and Onions, are cultivated, but not the Bananas and Cacti. 

 The hedges consist of Myrtle and Chesnut. Agriculture is more 

 successfully carried on here than elsewhere, on which account 

 few wild plants are met with but such as we had already 

 found in the lower region, and of those three that grew at a 

 still higher elevation. 



3. Region of the Chesnut. 



This commences at a height of 2030 feet, and is eminently 

 distinguished by the tall stout stems of the Chesnut, which 

 tree ascends to about 2950 feet. Those that are found still 

 higher are smaller, distorted, and bear no fruit. We stayed 

 longest in this region, and our success in collecting plants was 

 proportionally great. We found of 



Cryptogam^., twenty-three species, of which twelve were Ferns, one 

 Darea and Woodwardia, five Lichens, Anthoceros, Marchantia, Boletus, 

 two Jungermunnice, &c. 



Monocotyledons, twelve, of our common Genera; only one Carex 

 and a beautiful Cy perns. 



Dicotyledons, sixty-six. Rumex five, Clethra, Lobelia, Andryala, 

 Chamamelum, an arborescent Euphorbia, two shrubby species of Teucrium, 

 Cineraria, Disandra. We found nine of these species in the next region. 



4. Region of the Spartium. 



This terminated at a height of 3920 feet, and is singularly
