P. ionantha (Lentibulariaceae) was not described as a distinct species until 1961. It is a violet-flowered , carnivorous bladderwort. The leaves are oblong, fleshy and rounded at the tip and form a rosette approximately 15 cm in diameter. There are short glandular hairs on the upper leaf surfaces that capture insects. The flower is pale violet to white with a deep violet throat and dark veins, is 2 cm in diameter, and occurs on a leafless stalk (USFWS 1992). P. ionantha is considered a warm-temperate ping as it does not form winter resting buds. Considered a short-lived perennial, many die after a couple of years. While butterwort is their common name, some propagators refer to them as pings (DAmato 1998).
Distribution & Occurrence
Seepage slopes, bogs, transition zones between flatwoods and cypress stringers, roadside ditches, and depressions in wet pine flatwoods and wet prairies. Often in standing water (FNAI 2000).
|Over half of the 65 known populations are on the Apalachicola National Forest. A 5-year status review will be completed by the US Fish and Wildlife Service in 2008-2009.|
Conservation, Ecology & Research
In a study utilizing periodic matrix analysis and regression-design life table response experiments, P. ionantha demographics were found to be strongly dependent on prescribed fire events. It was shown that annual growing and biannual dormant season fires exerted the most positive influence on population growth rates. Maximum population growth rates occurred soon (<2 years) after a burn event (Kesler, Trusty, Hermann and Guyer, 2008).
Because P. ionantha does not tolerate shade, canopy closure in pine plantations results
Transplantation (Bok Tower Gardens)
St. Joseph Bay State Buffer Preserve: Application of frequent, preferably growing season, fire to wet savanna areas where P. ionantha occurs.
Tates Hell State Forest: Application of prescribed fire on a 3 to 4 year cycle.
Private lands: None
Conduct demographic studies to determine population stability, increase, and decline.
Determine habitat management requirements and develop management guidelines especially effects of differing fire frequencies and timing of application. Also effects of burning with corresponding drought/flood events.
Restoration research to focus on how best to reduce competitive vegetation such as titi in wetlands.
Phenological life history needs to be quantitatively described.
Conduct population biology studies
Collect seeds periodically from native populations to establish populations for study and as seed sources for reintroductions
Accession and store seed with the National Seed Storage Lab
Develop optimal propagation protocols for both seed and vegetative reproduction
