Utricularia nelumbifolia (Organ Mountains, Brazil). The habitat of this
species is remarkable. According to its discoverer, Mr. Gardner,** it
is aquatic, but is only to be found growing in the water which
collects in the bottom of the leaves of a large Tillandsia, that
inhabits abundantly an arid rocky part of the mountain, at an elevation
of about 5000 feet above the level of the sea. Besides the ordinary
method by seed, it propagates itself by runners, which it throws out
from the base of the flower-stem; this runner is always found directing
itself towards the nearest Tillandsia, when it inserts its point into
the water and gives origin to a new plant, which in its turn sends out
another shoot. In this manner I have seen not less than six plants
united. The bladders resemble those of Utricularia montana in all
essential respects, even to the presence of a few minute two-armed
glands on the valve. Within one bladder there was the remnant of the
abdomen of some larva or crustacean of large size,
* Prof. Oliver has given ( Proc. Linn. Soc. vol. iv. p. 169) figures
of the bladders of two South American species, namely Utricularia
Jamesoniana and peltata; but he does not appear to have paid particular
attention to these organs.

having a brush of long sharp bristles at the apex. Other bladders
included fragments of articulate animals, and many of them contained
broken pieces of a curious organism, the nature of which was not
recognised by anyone to whom it was shown.
Utricularia amethystina (Guiana). This species has small entire leaves,
and is apparently a marsh plant; but it must grow in places where
crustaceans exist, for there were two small species within one of the
bladders. The bladders are nearly of the same shape as those of
Utricularia montana, and are covered outside with the usual papillae;
but they differ remarkably in the antenn being reduced to two short
points, united by a membrane hollowed out in the middle. This membrane
is covered with innumerable oblong glands supported on long footstalks;
