4. MARGINS OF THE LAMINA. 



In reference to the margin, the lamina may be either 

 without notches of any kind as in the Yudzuriha (Fig. 25) 

 and Kohone (Fig. 33), or with notches of some kind as in 

 the Sakura (Fig. 16) and Momiji (Fig. 18) ; when without 

 notches the lamina is said to be Entire or Even, and when 

 with notches Uneven.

Among uneven laminae, some have their margins cut 

 into numerous small indentations, as in the Mume and 

 Sakura (Fig. 16) ; some have their margins deeply cut into 

 divisions which extend not more than half way down, as in 

 the Budo (Fig. 15) and Zeniaoi 

 (Malva sylvestris) ; some have 

 deeper divisions which extend 

 more than half way down, but 

 do not reach to the midrib or 

 the base, as in the Momiji (Fig. 

 18) and Yatsude ; and others 

 have still deeper divisions reach- 

 ing to the midrib or the base, 

 as in the Botan (Pceonia 

 Moutan) and Karatachi (Citrus 

 trifoliata) (Fig. 37). When its 

 margins are cut into small 

 indentations, the lamina is said 

 to be Dentate; when cut into 

 divisions extending not more than half way down, it is said 

 to be Lobed ; when the divisions are more than half way 

 down, it is said to be Parted ; and when the divisions reach 

 to the midrib or the base, it is said to be Divided.
