ON THE ANATOMY OF MAGNOLTAOE^. jQ^ 



the xylem consists exclusively of traeheids. The List oh;trncter is 

 only found in tlu' present o-enus and in 'ivochnilcndron nmono- Mao-- 

 iioliacete. The pnrenchyniatous cells of tlie pith are lignified even in a 

 young specimen, as in 7. Tasliimi, hut T have not here met with anv 

 scjerenchyniatous cells scattered aJ)ont. (as they are stated to l)e hv 

 l^-antl). Tlie le;if is almost sessile, and the til)ro-\'asculai' Ixnidles oi' 

 the very shoi-t jietiole present a semi-circular arrangement, as in 

 llJiriimi. The bundles are similarly arranged in the midrib. A 

 immher of resin-sacs are found in the mesophyll. In the epidermal 

 cells of the leaf, crystals are often met with, which are prohal)lv 

 calcium oxalate. 



Tribe III. Schizandreae. 



This trihe consists of the following two genera : 



Kadsura and Schizandra. 



The two genera are so closely related in anatomical characters 

 as to make it convenient to describe them togethei-. Of Kadsuin T 

 examined K. japonira, L., and of Scliizavdm I examined S. nufnt 

 Max.. and S. cliiiifnsis, I>ail. The three are small climhing shrubs. 

 found in se\'eral parts of Japan. When a cut portion of these 

 plants is put in water it yields a large quantitv of mucilage, which in 

 the case of 7v. japnuicn is S(^metimes used for dressing the hair. Tlu; 

 two species of Schizandra give out a sweet odour \vhen any j^oi-tion of 

 them is bruised, hut K. japonica gives out little or no odour, when 

 similarly treated. T'he berries of S. eliinensis are said to he edible. 



Stem. — The epidermis consists of a single layer of cells, and the 

 cuticle is not well developed. The hypodei-ma, is not represented. 

 The cork is well develo])ed directiv under the epidermis and is of the 

 usual type. Tn the cortical parenchyma there are scattered about a 

 few cells wliich contain oil globules (PI. TV, Fig. 14. rn) ; these are pro-
