The name Ornithocephalus means "Bird's Head" and refers to the shape of the column. There are approximately 20 species in this orchid genus, though there seems to be a great deal of confusion about the different species and I see many plants and photos that are mislabeled. They are all desirable for the abundance of blooms they produce even though the individual flowers may be very small. A well grown plant can be completely covered with flowers, usually in white or a combination of white and green. The name "cochleariformis" refers to the shell-like shape of the flowers.
