Blooming size totally leafless orchid. 8-10" leafspan for the large, 5-7" leafspan for the medium. Sallei is a very similar species to lindenii, but supposedly easier to grow. The hybrid of the two should result in very lindenii-like flowers and easy to grow plants.
Grow these mounted on craggy planks, or we grow them draped on a cattleya leaf, totally bare root.
