The apex of the lamina varies much in different leaves : 

 thus, it is either sharp as' in the Shidareyanagi (Fig. 31) ; 

 rounded as in the Kirishima (Bhododendron indicum, vour. 

 obtusum) and Tabirako (Fig. 30) ; abruptly pointed as in 

 the Medohagi (Lespedeza sericea) ; straight as if cut across 

 as in the Tulip-tree; or notched as in the Katabami 

 (Oxalis corniculata) . When sharp it is said to be Acute ; 

 when rounded, Obtuse ; when abruptly pointed, Mucronate ,- 

 when straight as if cut across, Truncate ; and when more 

 or less notched, Emarginate.

5. INSERTION OF THE LAMINA. 



The lamina is inserted on the stem in different ways : in 

 some leaves it arises immediately from the stem, as in the 

 Doku-utsugi (Fig. 19) and Yayemugura (Fig. 29); while 

 in others it is attached to the stem by means of the petiole 

 or the sheath, as in the Momiji (Fig. 18) and Sakura 

 (Fig. 16). The former kind of insertion is said to be 

 Direct, and the latter Indirect. 



Insertion op the lamina j Direct - 



t Indirect. 



Among the laminae whose insertions are direct, some 

 have their margins near the base not at all united except at 

 the point where they are attached to the stem, as in the
