Rhynchostylis gigantea var. harrisonianum or var. alba?
I just bought this Rhynchostylis gigantea.
In my book Wild Orchids of Thailand the white variant is named Rhynchostylis gigantea var. harrisonianum but on orchidspecies.com the white variant is named Rhynchostylis gigantea var. alba.
Is it two different variants or has the name changed?
