Dendrophylax is a genus of leafless neotropical orchids (family Orchidaceae) native to Mexico, Central America, the West Indies, and Florida.

One species, Dendrophylax lindenii, featured heavily in the book The Orchid Thief.

The bulk of these plants consists only of flat, cord-like, green roots with distinctive "track marks".

These white track marks are called pneumatodes and function in much the same manner as stomata allowing the photosynthetic roots to perform gas exchange to support photosynthesis.

Current evidence derived from molecular studies indicates that the original arrival from Africa which spawned this genus and the related genus Harriselia was a member of the subtribe Angraecineae with small leaves and flowers and a monopodial growth habit, and the leafless habit developed in parallel in both Africa and the Caribbean, since the genes are present in all members of the subtribe Angraecineae and the leafless habit is common in several genera within the Vandeae (Chilochista, Dendrophylax, Harriselia, and Microcoelia).
