There is another kind of gland which is almost
buried on the leaf surface. When a nutritious object, such as an insect, or a
tiny piece of meat, is placed on the leaf surface, these glands produce
digestive fluids. Often, the prey is completely covered with the fluids and
digested. Sometimes, the edge of a leaf curls up slowly if the prey is caught
near the leaf margin. This helps hold the digestive fluids in place around the
prey. As the digestion progresses, the nutrients from the dissolved insect are
quickly taken into the leaf and used for various growth activities of the plant.

clustering of rare Pinguicula ionantha plants in May, in the Florida
panhandle. Note the light green foliage color and rolled up leaf edges.
dull-red leaves belong to an imposing, Florida-endemic butterwort, Pinguicula
planifolia. This species prefers a very wet environment and an occasional
rain easily floods the habitat, completely submersing the plants in the shallow
water. In the Florida panhandle, in May.
In early spring, butterworts produce brightly
colored flowers at the tip of a slender stem rising from the rosette center.
Since butterworts are often covered with surrounding grasses in nature, it is
often difficult to find the plants without flowers.

flower is bilaterally symmetric (that is, the left and right are the same as in
a human face). A flower blooms dangling at the tip of a flower stalk (scape).
The corolla is divided into two lips, upper and lower. The upper lip is
three-lobed and the lower lip two-lobed. As a result, the flower looks like it
has five petals. The middle portion forms a corolla tube that ends in a narrow
spur. The spur is a nectar container commonly seen in many flowers. A hairy
structure located in the corolla tube is called a palate.

Pinguicula ionantha plant in Florida, in early March. This species grows
only in a very small area in the central Florida panhandle, and is considered
endangered. Collecting this plant from the field is prohibited.
A flower of
Pinguicula ionantha plant. Note a shallow notch at the tip of each of the
five petals, and a strongly protruded yellow palate. A short spur at the end of
the corolla tube is also yellow, with brownish veins.
