The following is the text I posted while waiting to find out the true identity. I leave it as a reminder of how difficult it can
be to correctly identify some species.:
Soon after posting this species I received an e-mail from Dr. B. Eugene Wofford informing me that Clematis pitcheri had not be seen in Tennessee since 1942! I had known when Darel Hess first pointed it out to me as 'Leatherflower' that it was unusual at least in the Cedar Forest area as I had been searching for plants in the area for years and had never before seen it. Once I identified it as C. pitcheri, based on the flower and leaves as no fruit had formed at that time, I discovered that it was recorded from only one county in Tennessee. This did not particularly surprise me as many counties are not well surveyed. Learning that it was thought extirpated from Tennessee was a surprise and of course called into question my identification. By this time the fruit had matured and the beaks of the achenes were much more hairy than expected. Soon the specimen will be checked by someone who knows this group well and we will learn for sure if this is a real discovery or just another example of my own ignorance.
Lore: The name 'Clematis' is from the Greek word 'clema' which means 'tendril'.
Similar Species: Clematis vines with urn-shaped flowers include;
Clematis pitcheri has somewhat similar flowers but the leaflets are prominently veined and the tails of the seeds are not plumose all the way to the tip.
Clematis versicolor may have very similar flowers but the leaves are glabrous and glaucous.
Clematis glaucophylla has red flowers and the leaves are glabrous and glaucous.
Clematis crispa has flowers with a narrow neck and wide flaring sepals with very crispate edges. The leaves are glabrous.
One of the best general guides to wildflowers of the North Eastern and North Central United States. Newcomb's key is an excellent, simple method for identifying plants. Newcomb has drawings for almost every plant mentioned that are excellent aids to identifying the species. Though only the more common plants are covered this is often the first book I pick up when trying to identify a wildflower.
This is perhaps the best of many field guides covering this region. Featuring 446 excellent color photographs (located with the text) and mentioning as similar to those illustrated are another 800 or so species for a total coverage of over 1,200 species. The start of each family section includes line drawings of some of the species showing important features. The text includes the usual description, bloom season, range, habitat and additionally includes information such as medical uses and lore and how the species was named. This is the official field guide of the Tennessee Native Plant Society.
