Many old books mention Rosa moschata nivea, which is none other than R. dupontii. It is surmised that this is R. moschata x R. gallica and therefore is, technically speaking, an Autumn Damask, but it flowers only at midsummer. It is very downy, which might point to R. brunonii, but its date of raising (1817) seems to preclude that.
