INSERTION OP THE LAMINA.

Doku-utsugi (Fig. 19) and Yayemugura 

 (Fig. 29) ; while others have prolonged 

 basilar lobes more or less united with the 

 stem, as in the Kaizaiku (Ammohium 

 alatum). The direct insertion as in the 

 former case is said to be Free, and that as 

 in the latter Adnate.

Among adnate leaves, some have their basilar lobes 

 united on the opposite side of the stem; some are 

 opposite and have their bases cohering around the 

 stem (Fig- 38) ; and others have their basilar lobes 

 prolonged down the stem. In the first case, leaves are said to be Per- 

 foliate ; in the second, Connate ; and in the last, Decurrent. 



Among the laminae whose insertions are indirect, or- 

 dinary ones are attached to the petiole or the sheath by their 

 ba'ses, but others are fixed to the petiole by a point more or 

 less within their margins, as in the Hasu (Fig. 23) and 

 Junsai (Brasenia peltata). The indirect insertion as in 

 the former case is said to be Basal, and that as in the latter 

 Intramurginal. When the lamina of a leaf is intramarginally 

 attached to the petiole, the leaf is termed Peltate.
