272 NATURAL SYSTEM OF JtfSSIEU. 



Embryo without albumen ; radicle straight. This 

 order embraces trees and shrubs, with alternate sim- 

 ple leaves, accompanied by stipules. Exemplified 

 in the Birch, Willow, Oak, and numerous other for- 

 est trees. 

 5. Coniferce. — Seeds enclosed in the persistent scales 

 of the cone, or in monospermous capsules. Embryo 

 cylindrical, placed in the centre of the fleshy albu- 

 men. Seminal leaves divided, appearing as if there 

 were several. Stem shrubby. Leaves persistent. 

 Exemplified in the Pines, Juniper, and Cedar. 

 Such is the outline of the system ofJussieu. Our 

 limits would not permit us to transcribe his characters ; 

 but it is thought that the preceding sketch, which has 

 been carefully compared with the original work, and 

 with others of a more recent date,* will be equally 

 satisfactory to those who wish to study this department 

 of Natural Science. 



* The author whom I have most frequently consulted, is Des- 

 fontaines, the learned associate of Jussieu, whose interesting 

 volumes on Trees, &c. well deserve an English translation.
