INTA has 2 Betulas albas, Linneus and Flor de la France (Coste) which seems
wrong.
"sensu" in this case means "also".
"Ga" means France mainland in Europe, does not includ the island of Corcega.

I am afraid I don't understand this one.
It seems to be using Betula alba as a current name?

I am still trying to find the correct classification for Betula
'Trost's
Dwarf.' Somebody said it depends on whether the leaves are fuzzy.
Well,
let me tell you the entire leaf, petiole, & twig are fuzzier than a peach.
