“…All three species have flower longevity that ranges from 2 to 3 weeks depending on the species and all have floral nastic movements. Prolonged periods of flower longevity also have been reported for other Pinguicula species (Molau 1993;García et al 1994;Zamora 1999;Alcalá & Domínguez 2012). It is possible that the flower longevity noted in our study could be a reproductive strategy to increase pollinator visitation and fertilization of ovules (i.e.…”

“…García et al . () reported that almost all the ovules in P. longifolia became seeds. These high levels of reproductive success are encouraging; however, they should be taken with caution as flowers and fruit losses have been observed at all the sites.…”

“…Nevertheless, it is possible that the stigmatic flap could have curved backward and come into contact with self-pollen, as has been found in other Pinguicula species (Heslop-Harrison 2004). Different from Pinguicula species in Europe where Diptera are the primary pollinators (Molau 1993;García et al 1994;Zamora 1999), Pinguicula species in the southeastern USA are pollinated primarily by Hymenoptera, specifically bees (bumblebees, carpenter bees, honey bees, and other smaller bees). This difference should not be surprising as most of the European Pinguicula species studied are found at alpine elevations where pollination by flies is common (Totland 1993;Arnold et al 2009).…”

“…Flower longevity also was assessed for each of the three Pinguicula species, as several studies have reported flower longevity for other Pinguicula species (Molau 1993;García et al 1994;Zamora 1999;Alcalá & Domínguez 2012). In addition, in 2013 and 2014 it was noted that a corolla would fall from the plant a few days after it was successfully hand-pollinated.…”

“…In the case of Pinguicula species, although several studies have been conducted to determine the reproductive ecology of this genus, the great majority of published work originates from Europe (e.g. Molau 1993;García et al 1994;Heslop-Harrison 2004;Jürgens et al 2012). These studies have shown that Pinguicula species are self-compatible and can be autogamous or xenogamous, are mostly pollinated by Diptera and Hymenoptera, and have relatively high fruit and seed sets.…”

Pinguicula (Lentibulariaceae) is a genus of more than 100 carnivorous plant species. A handful of comprehensive studies have examined the reproductive ecology of these species, mostly in Europe and none in the USA. During 2013–2016 different aspects of the reproductive ecology of P. ionantha, P. lutea and P. planifolia were studied at multiple locations in the Florida Panhandle, USA. All three species are of conservation concern within the study region and some aspects of their reproductive ecology may be contributing to their rarity. For all species, we conducted breeding system studies investigating xenogamy vs. autogamy, self‐incompatibility vs. self‐compatibility, pollen:ovule ratios, flower phenology and longevity, and pollinator visitation, as well as fruit and seed set differences among populations. All three Pinguicula species were determined to be xenogamous and self‐compatible, although the pollen:ovule ratios were extremely low. In addition, these species have floral nastic movements and flower longevity that ranges from 2 to 3 weeks depending on the species. Hymenoptera was identified as the primary group of pollinators visiting all species, although observed visitation events were low. All three Pinguicula species had extremely high levels of fruit set and seed set. Worldwide, Pinguicula species share similar breeding system and reproductive patterns. The rare status of P. ionantha, P. lutea and P. planifolia is more likely due to their ecological requirements, demographics and/or patterns of genetic diversity, than reproduction. This work is among the first and most comprehensive associated with the reproductive ecology of North American Pinguicula.
