` He certainly used mixed bunches a lot, but in this case I think the yellow roses are all the same type. Those that eventually show the ``quartered`` look in the middle (where the central petals are shorter and fold around one another to make sort-of divisions, often looking like 4 lines radiating from the centre) often look in earlier stages as if they might produce the high-centered form of a ``modern`` rose instead. For example, this gallery shows a ``normal modern`` flower starting to open that later opens to have the denser petals in the middle. I think there might be three different types in that bunch, the yellow roses, the little red ones with the delicate bracts, and that other leaf in the right foreground.   `
