Might we get a shot close up of that plant, as I now tend to veer more in the direction of P. malipeonse var. jackii fma. virescens (album) for the plant to the right. But I think it might be wise tol hold my guessing horses under control, untill it's possible to get a closer look at the plant itself!My guess would be: at the left P. micranthum fma. glanzeanum (alternatively fma. eburneum); at the right P. concolor fma. sulphurinum (or fma. album, if you prefer).
