Hi Pamela,
The flower of the first one looks very like Cistus x skanbergii, which I know Filippi supplies, but without seeing its habit I would be loath to give a definite ID. Do you have any photos of the complete shrub?
The second, as you say, is very difficult without seeing the flowers; there are so many crosses. From the leaf it looks like it has populifolius and ladanifer blood in it... Look for a blotch in the flower, if and when one appears, which would confirm this hypothesis.
