seedlings may be easily accounted for, inasmuch as there are some 
species of Nepenthes in which the entire inner surface of the pitcher 
is glandular (c.p., N. amp)ullaria and N. Hookeri), and his seedlings 
may have belonged to some such species. The occurrence, indeed, 
of such a large conducting surface in the pitchers of our hybrid, is 
somewhat surprising when its origin is considered. In the female 
parent, N. raflesiana, the conducting surface is limited to an incon- 
siderable area below the hinge of the lid ; which area, when traced 
round the upper part of the pitcher, is seen to be reduced to a very 
narrow stripe, just below the line of inflexion of the annulus ; while 
in the male parent, N. Chelsoni, there is practically no conducting 
surface at all, there being nothing left of it but the merest trace, 
running along below the said line of inflexion. The only sugges- 
tion I can make on the subject is that there may here be a reversion 
to some ancestor of the cross-bred N. Chelsoni. The following table 
represents the rather complicated genealogy of our seedlings, so far 
as ascertained : —

It will be observed that the male parent of N. Dominii has not 
been recorded. On examining this form (which closely resembles 
N. rafflesiana in the limitation of its conducting surface), I have 
been struck with the great breadth and almost horizontal expansion 
of the reflexed portion of the annulus ; and I would suggest that 
perhaps N. Veitchii^ which seems (I only know of tliis plant by 
figure) to exhibit this character to a still more marked degree, may 
have been the parent in question. 
In the second place. Hooker describes the first developed pitchers 
of his seedlings as destitute of annulus {Linn. Soc. Tra?is., xxii. p. 
418, footnote) ; while in ours this structure is very readily recog- 
nised, even in the leaf immediately succeeding the cotyledons, by 
its epidermis of imbricately disposed glassy cells, and its inflexion 
within the pitcher-orifice. As to this, I should almost be inclined
