(pronounced: dee-loh-MEE-liss)


Epidendreae subtribe Laeliinae


Caespitose epiphytes, lithophytes and terrestrials. Stems erect, leafy, clothed in persistent leaf sheaths. Leaves alternate, distichous, graduating in size from the base. Inflorescences terminal or subterminal racemes, rarely branched. Flowers somewhat nodding. Sepals and petals subsimilar, subequal, free, spreading. Lip three-lobed, with crest-like callus. Column stout, with a short foot; pollinia 8.


From the Greek di, meaning twice, and loma, meaning fringe, referring to the two fringed crests on the lip.


A genus of six species endemic to the Greater Antilles. Nir proposes to separate the Haitian D. filicina Dod as the monotypic genus Tomzanonia Nir on the basis of that species having a shortly clawed unlobed lip.
