be pointed out that it is the upperside of the leaf which in 
the figure is turned towards the reader. 
Fig. 81 shows us a stalked pitcher springing from the back 
of the midrib before the apex; in other specimens pitchers of 
this kind may grow more diminutive so far as to disappear 
altogether, in which case only a threadlike appendage of the 
midrib is left. It may also happen that the stalked pitchers 
or the mere stalks simply lengthen the midrib and also that 
the whole blade has been transformed into a pitcher (fig. $2). 
Leaves with very small blades are also to be found (fig. 83) 
as well as blades supported by uncommonly long petioles. We 
are also in possession of a blade, of which the middle portion 
has differentiated to a stalk, thus placed between two blades. 
The leaf which we represent in fig. 84 is a deviation of a 
quite different kind, which needs no description. The same 
applies to fig. 85. 
Chonemorpha macrophylla G. Don. 
Habitat East Indies. 
Coll. October 1896. 
Leaves with obtuse apex instead of acute, midrib not reaching 
the apex but splitting up into veins recurvous along the margins. 
Cerbera spec. 
Habitat Ambon. 
Coll. September 1895. 
After a pair of normal cotyledons there appear two leaves 
turned with their backs towards one another and partly grown 
together. The petioles have coalesced laterally and to such a 
degree that for the terminal bud there had been left just room 
enough to escape investment. The figure (86) shows with suffi- 
cient distinctness how far the midribs cohere and in what a 
peculiar way the margins unite.
