gularly lobed, or in 

 some cases, particularly 

 in A. japonica, it may 

 be slightly undulate or 

 even almost entire (e. 

 g. text- fig. II, 2). In 

 luxuriant specimens of 

 A. triphvlla the teeth 

 are increased in number, 

 and sometimes more 

 than ten are present, but 

 they remain deltoid in 

 shape and do not be- 

 come oblong lobes. In 

 A. japonica, on the 

 other hand, the teeth 

 of the lateral leaflets 

 often show a tendency 

 to decrease in number 

 and to become oblong 

 lobes by deep incision.

AcMys japonica .Maxim, x -* t . show such a deepening 



of a sinus, and, in one of the leaflets in 1, it has resulted in the 

 formation of an extra leaflet. 



Although in extreme forms of these two species the incision 

 of the leaflets is quite different, yet on the whole the shape and 

 dimension of the leaf are of little use for diagnostic purposes. 



The Inflorescence. 



The inflorescence terminates the stem which forms an upright 

 scape, very similar to the petiole but usually taller. Flowers 

 are densely clustered together in a spike 2-5 cm. in length, 

 which is terminated by a perfect flower. The spike i> continuous 

 in A. triphvlla, but is more or less interrupted in A. japonica 

 as Maximo wicz correctly describes (14). Hooker (10, p. 30)
