I can think of them only as ruffles because they share some other features of ruffles....such as being rounded and having edges that are sometimes pie crusted or edged with gold or lemon..... and I believe they are capable of producing even more elaborate edges that include teeth, double edges, etc.as you would normally see along petal edges. They are different than the "fins" that you often see in cristate tissue arising from midribs and alongside midribs and projecting from throats. I get those, too. Ruffles appearing in odd places are becoming rather commonplace, I think, with hybridizers working with sculpts.
