with star-shaped flowers ; as the Ladies' Bed- straw 

 (Galium boreale), the Wood-roft' (Aspemla), &c. In 

 the greater part of the Temperate Zone they are 

 herbaceous ; but in the warmer part grow into shrubs 

 and trees, which last pass over into the Torrid Zone. 

 Of such are the China-trees, on the left declivity of 

 the Andes ; and in the warmer countries, the Coffee-

23. The Order of the Mallows (Malvacea) is in its 

 greatest luxuriance and number in the Torrid Zone, 

 where large trees grow with short stems of great cir-

 B read tree (Adansonia digitata) has a stem of 12 feet 

 high and 30 in diameter. The Order of Mallows
