 smell, like that of tainted beef, attracts flies, which aid in the work of 

 fertilization. The Aristolochia (Pig. 186) ends this subdivision. 



_ 97. Suhdwidon II. Ovary Free. Perianth umally dis- 

 tinct; sometimes 0. — The Pitcher-plant (Fig. 113) opens 

 this subdivision. The Orders crowd upon us; we shall 

 name only such as are illustrated in these Lessons: the 

 Euphorbia (Fig. 146) ; the Willow (Fig. 69, A), the Sweet- 

 gale (Fig. Ill) ; the Plane-tree (Fig. 98) ; the Birch (Fig. 



69, B). In the Willow and 

 these succeeding Orders the 

 flowers are diclinous and in 

 catkins; they 

 are sometimes 

 grouped with the 

 Oaks and Wal- 

 nuts, and called 

 Ameniales (L. 

 amentum, cat-

 the Fig (Fig. 140), Dorstenia (Fig. 141), Bread-fruit (Fig. 213), and 

 the Cow-tree (Fig. 238). The Protea Order is represented by the

 (Pig. 230) ; the Laurel Order by the Cinnamon (Fig. 170) ; the Goose- 

 foot Order by the Strawberry Elite (Fig. 120). The Amaranth is here
