wing; much inflated, hooded, yellowish green with dark maroon or
purple lines and veinings, 4 to 12 in. long, curved, in a tuft

"What's this I hear
About the new carnivora?
Can little piants
Eat bugs and ants
And gnats and flies? -
A sort of retrograding:
Surely the fare
Of flowers is air
Or sunshine sweet
They shouldn't eat
Or do aught so degrading!"
There must always be something shocking in the sacrifice of the
higher life to the lower, of the sensate to what we are pleased
to call the insensate, although no one who has studied the
marvelously intelligent motives that impel a plant's activities
can any longer consider the vegetable creation as lacking
sensibility. Science is at length giving us a glimmering of the
meaning of the word universe, teaching, as it does, that all
creatures in sharing the One Life share in many of its powers,
and differ from one another only in degree of possession, not in
kind. The transition from one so-called kingdom into another
presumably higher one is a purely arbitrary line marked by man,
and often impossible to define. The animalcule and the
insectivorous plant know no boundaries between the animal and the
vegetable. And who shall say that the sun-dew or the bladderwort
is not a higher organism than the amoeba? Animated plants, and
vegetating. animals parallel each other. Several hundred
carnivorous plants in all parts of the world have now been named
by scientists.
It is well worth a journey to some spongy, sphagnum bog to gather
clumps of pitcher-plants which will furnish an interesting study
to an entire household throughout the summer while they pursue
their nefarious business in a shallow bowl on the veranda. A
modification of the petiole forms a deep hollow pitcher having
for its spout a modification of the blade of the leaf. Usually
the pitchers are half filled with water and tiny drowned victims
when we gather them. Some of this fluid must be rain, but the
open pitcher secretes much juice too. Certain relatives, whose
pitchers have hooded lids that keep out rain, are nevertheless
filled with fluid. On the Pacific Coast the golden jars of
Darlingtonia Californica, with their overarching hoods, are often
so large and watery as to drown small birds and field mice. Note
in passing that these otherwise dark prisons have translucent
spots at the top, whereas our pitcher-plant is lighted through
its open transom.
A sweet secretion within the pitcher's rim, which some say is
intoxicating, others, that it is an anaesthetic, invites insects
to a fatal feast. It is a simple enough matter for them to walk
into the pitcher over the band of stiff hairs, pointing downward
like the withes of a lobster pot, that form an inner covering, or
to slip into the well if they attempt crawling over its polished
upper surface. To fly upward in a perpendicular line once their
wings are wet is additionally hopeless, because of the hairs that
guard the mouth of the trap; and so, after vain attempts to fly
or crawl out of the prison, they usually sink exhausted into a
watery grave.
When certain plants live in soil that is so poor in nitrogen
compounds that protein formation is interfered with, they have
come to depend more or less on a carnivorous diet. The sundew
(q.v.) actually digests its prey with the help of a gastric juice
similar to what is found in the stomach of animals; but the
bladderwort (q.v.) and pitcher-plants can only absorb in the form
of soup the products of their victims' decay. Flies and gnats
drowned in these pitchers quickly yield their poor little bodies;
but owing to the beetle's hard-shell covering, many a rare
specimen may be rescued intact to add to a collection.
A similar ogre plant is the YELLOW-FLOWERED TRUMPET-LEAF (S.
flava) found in bogs in the Southern States.
