36 PICTURE OF ORGANIZED NATURE. 



all blossom in the spring ; and some of them, for 

 instance the Hazle, Alder, Willow, and Birch-trees, 

 very early. Among these, the Willow is most diffused ; 

 beginning at the snow-line, to the level plains of the 

 Equatorial region. 



16. The Order of Coniferous plants (Coniftrce) is 

 closely allied to the Amentaceae. It begins at the 

 same distance from the snow-line; partly in the com- 

 mon Juniper (Juniperus communis) ; partly on moun- 

 tains, in the Dwarf- Pine (Pinus pumilio), which is 

 only a species of the common Fir, gradually becom- 

 ing tall trees and forming large forests. In the warm 

 countries, instead of these, the Casuarines (Casua- 

 rina) occur. The region which coincides with the 

 50th degree N.L. may be regarded as the native 

 country of this Order. 



17. The Order of the Caprifolia commences at 

 some distance from the snow-line, in herbaceous and 

 shrubby individuals (Cornus suecica, Linnea borealis) 

 soon turning into shrubs and trees ; extending through 

 the Temperate to the Torrid Zone, where they, 

 chiefly with the Rizophora Mangle, form large groups 

 of trees. In the Temperate Zone, the following- 

 Genera of this Order occur : the Honeysuckle (Loni- 

 cera) y Elder-tree (Sambucus), pliant Mealy-tree (Vi- 

 burnum), and Dog. Wood or Cherry (Cornus). The
