[Edited by wcutler: this conversation started in the Takasago thread; in this thread, I've removed the first two paragraphs that were about Takasago.] ... I was calling Korean hill cherry P. verucunda for years, until I actually looked at it. Now, I prefer to use P. speciosa var. pubescens, as the tree seems to differ so little from Japanese hill cherry (P. speciosa) except in the degree of pubescence and a few other minor characters. But again, I'm willing to entertain another point of view, as long as it's coherent and based on solid evidence.
