CHAP. XI.] JUGLANDACEiE. 175 



Corylacece or Cupiillferse, contains the Oak, the 

 Beech, the sweet Chestnut, the Hazel, and the 

 Hornbeam ; the fifth, Platanacese, is generally 

 considered to include two genera ; viz., Platanus 

 and Liquidambar, though this last is, by some 

 botanists, placed in a separate order called 

 Balsamaceae ; and the sixth, Myricacese, or the 

 sweet Gale family. All the genera included in 

 these orders, with the exception of those belong- 

 ing to Juglandaceae, were formerly comprised 

 in one order, which was called Amentacese ; 

 from the word Amentum, which signifies a catkin. 

 The seventh and last order I have mentioned 

 in this chapter is called Garryaceae, and consists 

 of one single genus, Garrya, only lately known 

 in Europe. Of all these orders the largest and 

 most important is Cupuliferse, as it includes, 

 among other valuable trees, the Oak and the 

 Beech. All the plants mentioned in this chapter 

 have their male and female flowers distinct, 

 many of the genera having them on different 

 plants ; and the male flowers are always in cat- 

 kins, generally long and cyhndrical, but some- 

 times round and ball-shaped. The female 

 flowers are sometimes in catkins also, but some- 

 times they are produced singly or in pairs. 

 The flowers of both kinds are without petals, or 

 with such as are inconspicuous ; and sometimes 

 without even a calyx, but they are always fur-
