Pinguicula planifolia

The species name, planifolia, loosely translating to 'flat leaf,' comes from the Latin planus, meaning flat and folis, which means leaf.^[2]

Another identifying feature of Chapman's butterwort are the flowers which differ from most Pinguicula by the deep notches in the petals, with incisions close to half the petal length.^[3] Flowers are often purple, sometimes pinkish to white in color. The scape is often purple in color, covered in tiny hairs.^[2]

It is native to the southeastern United States, in southern Mississippi, Alabama, the panhandle region of Florida, and the extreme southeast extent of Louisiana.^[4]

Throughout their distribution, Chapman's butterwort can be found alongside many other carnivorous plants including Sarracenia and Drosera. Commonly found in depressions of pinelands, bogs, wet prairies, and swamps, as well as man-made drainage ditches, retention ponds, and edges of roadways.^[3] Due to the moisture requirements of the plant, it is common for the habitat to be partially submerged during wet seasons and due to weather phenomona. The Chapman's butterwort can thrive in a terrestrial, exposed environment, as well as fully submerged.^[3] Insects can be captured and digested above and under water.

Chapman's butterwort is listed as threatened in the state of Florida due to habitat loss from drainage of wetlands, development, lack of prescribed burns, and illegal collection.^[2][3]
