Insectivorous Plants ( Part II). 
wet places ; stem creeping prostrate, or upright and ascending 
by tendrils ; leaves with or without flattened lamina , sometimes 
tendriliform , ascidiform , and adapted for insect-catching ; 
flowers regular , solitary , racemose , hermaphrodite or 
dioecious , entomophilous ; sepals , 5> 4> ^ 3, green or coloured , 
hypogynous ; petals , 5, 4, o, greenish or coloured when present; 
stamens indefinite ( rarely definite ), hypogynous , /m* connate 
into a tube , anthers i-celled ; pistil syncarpous , 0/5, 4,^r 3 carpels , 
with central (axile) placentation ; ovules anatropous , horizontal 
or ascending; style short , with truncate flattened or expanded 
extremity , bearing 5, 4, 3 stigmatic lobes ; fruit a capsule , 
surrounded by the persistent calyx , dehiscing loculicidally into 
5, 4, 3 lobes when ripe ; seeds small , ovoid , elongate- 
appendiculate or zvinged , testa crustaceous or loosely reticulate ; 
albumen fleshy ; embryo straight in the albumen. 
I have been able to examine minutely the flowers of most of the 
Nepenthes, and in all the under-surface of the sepals is clothed 
with fine hairs like those on some parts of the foliage-leaf, 
particularly the pitcher. Lying amongst these may be a few 
perithecioid glands which in iV. bicalcarata resemble those of 
the under surface of the lamina and are equal in size or larger. 
From 3-6 may occur on each sepal, but they are absent or 
very scarce in most of the species. 
Of special interest is the fact that in N. Pervillei , greatly 
isolated geographically and modified morphologically, the 
flower-stalks as well as the sepals are abundantly glandular. 
The glands of the stalks are very abundant, small, consider- 
ably elongated, and sunk usually in rather deep cavities 
(Plate XX, Fig. 18). The upper surface of the sepals in every 
species is closely covered with nectar glands (Plate XX, Figs. 
19, 20), which even an expert could not distinguish from the 
attractive glands of the inner lid-surface. Thus a preparation 
from the marginal part of the lid and from the upper sepal in 
N. khasyana , when placed under the microscope side by side, 
would be undistinguishable, except perhaps from the slightly 
smaller size of the glands in the latter. 
There is a decided tendency in many species to sinking and
