the true Honeysuckles (Fig. 132): but here it is a pnir of oppo- 

 site leaves, with their contiguous broiul bases grown togetlier, wliich 

 makes what seems to be one round leaf, with the stem running 

 through its centre. This is seen to be tlie case, by comparing 

 together the upper and the lowest leaves of the same brancli. 

 Leaves of this sort are said to be; connnte-perfoUafe. 



^J^'^ 175, tquitant Leaves. While ordinary 



leaves spread horizontally, and present 

 one face to the sky and the other to the 

 eartli, there are some that present their 

 tip to the sky, and their faces right 

 and left to the horizon. Among these 

 are the cquitant leaves of the Iris or 

 Flower-de-Luce. On careful ins{)ection 

 we shall find that each leaf was formed 

 folded together kngtli- 

 wise, so that what 

 would be the upper 

 surface is within, and 

 all grown together, ex- 

 cept next the bottom,

the next younger one. It was from their strad- 

 dling over each other, like a man on horseback (as 

 is seen in the cross-section. Fig. 134), that Linnteus, 

 with his lively fancy, called these equifant leaves.

The leaves of Iris just mentioned show one form 

 of this. The flat but narrow 

 leaves of Jonquils, Daffodils, 

 and the like, are other in- 

 stances. Needle-shaped leaves, 

 like those of the Pine (Fig. 

 140), Larch (Fig. 139), and 

 Spruce, and the aid-shaped 

 as well as the scale-shaped 

 leaves of Junipers, Ked Ce-
