The plant itself looks like Den. nobile.
It used to be considered a very rare and endangered dendrobium species but these years, wild plants have been found in China and southeast Asia. Also, seedlings are available. It is more common to see them now.
Thanks. Some hybirds of it have been bred these years.
For example, Den.linawianum x Den. Hamana Lake 'Dream'
is among which.
