I did not know willosum has such a wide range of habitat.
Lai Chau is so far north-west of North Vietnam almost to the border with Laos while Nha Trang is the beach resort region in South Vietnam.
I am curious to see the differences too.
Good info, thanks MichaelHi,
I think the paph. villosum var. laichauense looks like the Paph villosum var boxalli. The plant of my friend bloom last week.
