Scouts Laura and Mary Ellen and I did the Cambie median today, to write down the names from all the new cherry tree tags. But what got our attention were all these old trees that we've been identifying as 'Somei-yoshino', that still had more blossoms than we'd have expected, and that I thought showed a corymb inflorescence. But our Ornamental Cherries in Vancouver book and Kuitert's Japanese Flowering Cherries both say that 'Somei-yoshino' and 'Akebono' have 3- to 4- flowered umbels. So the first question is: have I misunderstood what a corymb is? These are umbels? Here's a young 'Akebono' that seemed to have the same structure. If they're umbels, then I'm happy calling them 'Somei-yoshino'. But if they're corymbs, then the second question is: Are they 'Somei-yoshino' with corymbs or if not, what are they?
