spreading from the Warm to the contiguous parts of 

 the Temperate Zone, and ending in about the 45th de- 

 gree of Latitude. The Citron-tree (Citrus), Lemon -tree 

 (Limonia), and the Tea-tree (Thea), are of this Order.

 is diffused over the Torrid, and warmer parts of the 

 Temperate Zone, nearly as far as 45 Latitude. It 

 contains a great number of succulent plants of

 species of the Fig-Marygold (Mesembryanthemum) 

 are met with in the green-houses of the Temperate 

 climate. 



OF ORDERS NOT DESCRIBED IN THE PICTURE. 



1. That of the Birthwort (AristolochicB), a native 

 of the Torrid Zone. In the colder half of the Tem- 

 perate Zone, this Order has but few herbaceous 

 specimens ; as the Asarabacca (Asarum), and the 

 Aristolochia clematitis. 



2. The Order of the Wild-Olives (El&agni) begins 

 in the district of the Alps, in a few herbs ; namely, 

 the Bastard toadflax (Thesium alpinum), gradually 

 becoming shrubs and small trees ; and in Ihe forest 

 of the Torrid Zone, trees of a large size. In the 

 Temperate Zone, the Sea-Buckthorn (Hippophad), 

 and the Oleaster (Elceag?ius), are of this class.
