Sarracenia psittacina
The pitcher leaves are
typically decumbent in this species, lying flat on the ground, though in a wet
condition the leaves tend to rise to 45 degrees. The pitcher in this species has
a well developed hood, forming a globose dome structure at the leaf tip. A
large, undulating ala and the pointed tip of the hood gives the appearance of
the beak, explaining the common name, parrot pitcher plant.

As devilish as it may
sound, areoles are strategically positioned to persuade the prey already in the
dome interior to move forward deeper into the pitcher tube. Lobster pot
structure prevents the prey from retreat its steps... only forward due to
intermeshing directional hairs.
Somewhat difficult to spot
in the field -- it is low on the ground and deep in grass....
Flowering occurs in April
to May. Flower scape reaches 40 cm tall and a deep red petals surround a green
to pale yellow umbrella-shaped pistil.
This species retains
pitchers well during the winter months. and well preserved pitchers can be seen
along with the flower. However, because of the low-lying posture of the pitcher
leaves, there appears to be no conflict between pollinator and prey.
The plants prefer a wetter
habitat compared with other pitcher plant species. When the soil is flooded
after a rain, the plants are known to capture aquatic preys such as tadpods in
the wild. Looking at the well conceived leaf structure, it is easy to see
they are well equipped for aquatic feat.
Designed to capture
crawling or aquatic prey instead of relying on the gravity-feed, as in other
erect pitcher plant species.

The plants grow
along the Gulf Coast and into the southern part of Georgia (Okifenikee) where
uusually large, giant form of the plants can be found (growing up to 40 cm
leaf).

are stimulated, the clam-shell-shaped trap closes suddenly --- often in less
than a half second --- fast enough to capture such agile insects as a fly quite
comfortably. Intermeshing marginal spines effectively prevent the prey's escape.
After the initial rapid closure, the insect's struggle inside the trap further
stimulates the trigger hairs, causing the trap lobes to close even more tightly.
In a day or so, the trap is seen tightly sealed around the free margins o
