Sarracenia flava
In spring, the plant produces large flowers with 5-fold symmetry. The yellow petals are long and strap-like, and dangle over the umbrella-like style of the flower, which is held upside down at the end of a 50 cm long scape. The stigma of the flower are found at the tips of the 'spokes' of this umbrella. Pollinating insects generally enter the flower from above, forcing their way into the cavity between the petals and umbrella, and depositing any pollen they are carrying on the stigmata as they enter. The pollinators generally exit the flower, having been dusted with the plant's own pollen, by lifting a petal. This one-way system helps to ensure cross pollination. It traps insects using a rolled leaf, which in this species is a vibrant yellow in color, and up to over a meter in height (although 50 cm is more typical). The uppermost part of the leaf is flared into a lid (the operculum), which prevents excess rain from entering the pitcher and diluting the digestive secretions within. The upper regions of the pitcher are covered in short, stiff, downwards-pointing hairs, which serve to guide insects alighting on the upper portions of the leaf towards the opening of the pitcher tube.
It is native to the New World. Its range extends from southern Alabama, through Florida and Georgia, to the coastal plains of southern Virginia, North Carolina and South Carolina. Populations also exist in the Piedmont and mountains of North Carolina. Seen at the NC Botanical Garden.
