244 Bower. — On the Pitcher of Nepenthes: 
which represents the young lid (Figs, n and 13, A), The rela- 
tion of the lid to the apex, which develops into the spur, is 
essentially the same as in N. phyllamphora , but it is only at a 
subsequent period that the two-lobed character of the lid 
becomes apparent (Figs. 14-17). The apex ( ap ) may in this 
species remain a simple cone, or it may occasionally assume 
an irregular form (Fig. 16), as is so frequently the case in 
N. phyllamphora . 
It would be desirable to study the development of the 
pitchers in the first plumular leaves, and especially so after the 
interesting observations of Sir J. Hooker and subsequently of 
Prof. Alexander Dickson 1 on such leaves in the mature state. 
Unfortunately I have been unable to obtain specimens of seed- 
lings in the earliest stages ; I owe, however, to the kindness of 
Messrs. Veitch, of Chelsea, two of the youngest seedlings they 
could supply of N. phyllamphora . One of these had five, the 
other six expanded leaves ; they were not so young as those 
described and figured by Hooker, though they were of such 
age that the tendril was not intercalated between the pitcher 
and the expanded base of the leaf, and the wings were ob- 
viously continuous from the base up to the pitcher. In the 
mature leaves of these young plants the spur was much less 
clearly to be recognised than in pitchers of more mature 
plants of this species, while the irregular fringes were larger 
in proportion than in older specimens ; the lids were quite as 
clearly lobed as is usually the case in mature plants. Exam- 
ination of the development of the leaves of these seedlings as 
exhibited in their terminal buds gave practically the same 
results as those above detailed for older plants, the relation 
of apex and lid, and the two-lobed character of the latter 
being quite similar. The evidence from these somewhat ad- 
vanced seedlings cannot be regarded as conclusive, but as far 
as it goes it supports the view now to be put forward. 
The above facts coincide in all essential points with the 
observations of Sir J. D. Hooker, and they lead me to the
