'Russi Major'

russi "major" [actually a Lemoine hybrid between russi and wittmanniana, but usually found listed among species],

The view of A.P.Saunders, that the cultivar 'Russi Major' might be a hybrid between P. mascula ssp. russoi and P. wittmanniana is highly questionable. In the lack of any evidence pro or contra this view I maintain it here as fact, nevertheless.
