Hello All! I've just finished posting a new field report on the FCPS site that is quite interesting, regarding the hypothesis of possible hybridization between Pinguicula planifolia and Pinguicula ionantha. It can be found here; www.floridacarnivorousplantsociety.org/pplanifoliarevisited.htmHappy Growing! Brian. Below; photo taken in habitat where P. planifolia and P. ionantha zones merge in the Fl. Panhandle...

Hey Brian,
Are you familiar with work published by, I think, Godfrey, that talks about the hairs on the flower palate? The species can be distinguished based upon the characters of these hairs. It might be a good idea to check if the hairs of P. ionantha and P. planifolia are different. Does someone here have the appropriate papers or references at their fingertips?
The work may have been reproduced in Godfrey and Wooten (1981) Aquatic and Wetland Plants of Southeastern United States.
Anyway, it would be very interesting if your plants with intermediate vegetative characteristics also had intermediate flower hair characteristics, too!
Barry

Hi Barry! Yes, I have discussed the floral differentials between the two species with other growers over the years, who have also mentioned Godfrey and Wootens work as a reference for discernment, along with the different chromosome counts which supposedly render hybridization impossible between the two. However, I can't help but think there's something more. We've both seen the purple-flowered Pinguicula ionantha and the white-flowered Pinguicula planifolia while in the field, i.e. one species sharing the others flower color. Whereas P. ionantha typically has the exuded beard on it's flower, I've seen P. planifolia with exuded beards as well. Visable flower and physical traits between the two are so often closely shared, that i truly believe they are very closely related, more so than we may think... Sounds to me like a great excuse to spend a week in the Panhandle come November, when flowering begins! Come on down.... Happy Growing, Brian.
