Prior to acquiring this plant, I didn't know (and/or believe) that S. rubra ancestral grew in Peach Co, GA! This is the first decent pitcher the plant has produced, and I must say it is definitely very unique and different from any other ancestral I've ever seen. It's quite a vigorous grower too, and almost looks a little "jonesii" to me, moreso than the other populations that look like gulfensis ancestors:

If you don't mind me asking, where did you get this plant? We were the ones who originally discovered this rubra in Peach County (only one population at that time) and several other west Georgia counties.
Jeez Louise that thing looks just like the CCs jonesii clone! I looked up Peach Co, GA (fantastic name for a county, btw) and it's pretty much smack dab in the center of the state. Mike (and others) do you have any info about where in GA the various CP taxa reside and where this rubra fits in with respect to those plants and other rubra-group taxa? I know there are flavas in both the east and SW, but not in the middle, while you've got purpurea in the east and rosea in the SW. The GA leucs are also from the SW-ish part of the state (Sumter Co). Are there any other pitchers besides this one in central GA? Seems like GA is a zone of disjunction / limit range for these various Sarrs, and then this (very handsome) rubra pops up...
Calen and Jeff-there is a disjunct population of S. rubras that can be found in Southern South Carolina all the way to western-cetral (ish) Georgia. Some speculate these are the "ancestral" genetics to S. rubra ssp. gulfensis. In comparison to the Taylor County, GA ancestral plants (http://sarracenia.proboards.com/thread/253/rub-ancestral-taylor-ga-updt ) , these peach county genetics look entirely different. A fairly large trap just opened, and it's about a foot in height. I'm guessing this plant can get a lot taller.
Off the top of my head, I know Ancstral rubras are found in taylor and crawford counties. I think they may have also been found in marion and macon counties, but I'm not positive. In South Carolina, there is a population in Lexington Co, although it's debatable as to whether these are ancestrals or not. Phil Sheridan is perhaps the foremost expert on these plants, so maybe he has some more info on them?
I have a S. rubra 'long lid' that some thought may be a jonesii. Here's a shot from another post-long lid is on the left, and jonesii is on the right:
Perhaps the peach co, GA population is genetically similar to S. jonesii, and I too see a very close resemblance. It almost looks like something between a gulfensis and a jonesii to me. Perhaps because these populations are so isolated from other rubras, they have "evolved" on their own.

Lots to discuss here but more than I want to get into this minute. We originally used the term "ancestral" for these plants on one of our "Noteworthy..." articles in CPN a couple decades back. Also, if you go to our research link in the five step process at www.pitcherplant.org, and read the Georgia white cedar papers in "Proceedings", you can read about the phytogeography of these plants and thir proposed migration and ancestry. I also wrote the text for this "undescribed taxon" in Stewart and Don's Sarracenia monograph. I plan on formally describing this entity in a peer reviewed journal, at some point, when I am comfortable we have a means of differentiating it based on statistically significant features.

iona: Hello everyone! I was wondering if anyone had extra Pinguicula grandiflora plants or seeds to spare, and they are so difficult to get in the US but think it’d be a great addition to my big garden.
