They are all Flos adriana.

In Flos asoka there is a broad brown sub-basal band from costa to dorsum(inner margin).
The band may be parti-coloured & composed of merged spots & bars.

In Flos adriana this same HW sub-basal band is incoplete ,ending midway into a couple of round spots, or split into a couple of bars ,often with the inner weak & obscure.
