Virginia ; in Africa the gum-dropping acacia ve- 

 getates on the hills of Mogadore : in Asia, to the 

 west of the Caspian Sea, Mr. von Bibersiein saw 

 the plains of Shirvan covered with the acacia 

 stephaniana. If we more carefully examine the 

 plants of the island of Lanzerota and Fortaven- 

 tura, which are nearest the coasts of Morocco, 

 we shall perhaps find a few mimosas among so 

 many other plants of the African Flora. 



The second zone, that of the laurels, contains 

 the woody part of TenerifFe ; this is the region 

 of the springs that rise up amidst a turf always 

 verdant, and never parched with drought. Lofty 

 forests crown the hills, that lead to the volcano, 

 and in them find four species of laurel an oak 

 nearly resembling the quercus Turned *f of the 

 mountains of Thibet, the visnea mocanera, the 

 myrica faya of the Azores, a native olive (olea 

 excelsa), which is the largest tree of this zone, 

 two species of sideroxylon, the leaves of which 

 are extremely beautiful, the arbutus callicarpa, 

 and other evergreen trees of the family of myrtles. 

 Bindweeds, and an ivy very different from that 

 of Europe (hedera canadensis) entwine the trunks 

 of the laurels ; at their feet vegetate a number- 



* Lauras indica, 1. foetens, 1. nobilis, and 1. Til. With 



these trees are mingled the ardisia excelsa, rhamnus gland u- 



losus, erica arborea, and e. texo.
