S. oreophila, heavily veined form is best recognized when the pitcher fully opens and is standing in direct sun for a week or so. This will give the color a real chance to shine through. Oreo's can be anywhere from veinless, to a rare all maroon plant. And all points in between. The oreo "Don Schnell", Peter D'Amatos cultivar, is about as heavily veined as I have ever seen, and not in cultivation at this time. The maroon form was found by yours truly on the Little River in Alabama in a, at that time, unknown stand. They have since been put under F&WS protection. I doubt that these will ever be in cultivation, but I think that the rare color is still locked in their genes, and is just a matter of time before someone out there comes up with another one from another plant that is in cultivation. Show us a picture of a pitcher after it has been in the sun for a week, and an absolutely positive ID can then be made. Also, oreophila's can grow in much dryer situations than most other pitcher plants, but do best in damp to wet soil.
