LABORATORY PRACTICE 



III. Examine a large opening bud of a Maple or Currant, 

 and after removing the bud-scales notice : 



1. The short petioles of the young leaves. 



2. The blades folded together so as to make several longi- 



tudinal plaits or folds. 



3. Cut across the middle of a bud, examine the cut surface 



with a lens, and make a sketch, showing 



4. The relative positions of the folded leaf-blades and 



5. The method of folding in each case. 



6. Such praefoliation as this, is called plicate or plaited. 



IV. Examine a terminal opening bud of a Magnolia and 

 after removing the bud-scales, notice : 



1. The young leaves, folded together along the midrib, 



bringing the inner surfaces together. 



2. Cut across the middle of a bud, examine the cut surface 



with a lens, and make a sketch, showing 



3. The relative arrangement of the folded leaf-blades and 



4. The method of folding in each case. 



5. Such prsefoliation as this, is called conduplicate. 



V. Examine the opening buds of the Tulip Tree in the 

 same way and notice : 



1. The conduplicate blades. 



2. That the blades are also bent forward upon the petioles. 



3. Make a sketch of a single leaf to show these points. 



4. The leaves of the bud of the Tulip Tree, then, show not 



only conduplicate but also reclinate pr&foliation. 



VI. Examine a large opening bud of the Cherry or of 

 the Japanese Quince, and after removing the bud-scales, 

 notice :
