Jerry's Carnivorous Plants
Carnivorous Plants,You Can't Have Just One.
Pinguicula use an active flypaper-type trapping mechanism . The surface of Pinguicula's broad ,
flat leaves are covered with a multitude of two types of glands . The
first , larger type , sits atop a small , hair-like structure and produces
a sticky substance that holds the victim in place . This gives the leaf
a greasy look , inspiring the genus' common name . The movement of the
prey causes the second , smaller type of gland to produce a slightly
acidic substance which digests the soft portions of the insect's body .
In many species , the edges of the leaves curl upward , perhaps
preventing nutrient-rich fluids from running off . Butterworts are found
primarily in the Northern hemisphere . They range from arctic, northern
species to tropical evergreen forms . Many of the more popular and easy
to grow species come from Mexico, where the conditions allow for some
seasonal variation in growth habit , but do not require an actual
dormancy period . Pinguicula species fall into three groups : those
forming winter resting buds , those that produce the same type of leaf
year-round (homophyllous growth type), and those that produce a large
summer leaf , and a smaller winter leaf (heterophyllous growth type) . Pinguicula produce
some of the most attractive flowers among carnivorous plants . Many
species flower freely, and the flowers can remain for months.
