Found in Cuba, Jamaica, Dominican Republic, Haiti, the Windward Islands, Trinidad & Tobago, Fr Guiana, Surinam, Guyana, Venezuela, Colombia, Ecuador and Brazil climbing over trees at elevations of 600 to 700 meters as a giant sized, warm growing, climbing epiphyte with an erect, slender, wiry stem with shorter than the internodes, papery, ovate, lanceolate, subcordate to cordate, acuminate, rigid and recurved apcially, sessile to short-petiolate base leaves that blooms in the spring on an axillary, successively to 5 or more flowered inflorescence and carrying sessile, fragrant, often cleistogamous flowers

"A very distinct Caribbean and Guyanan species. The slender plants with small, elliptic leaves, which are much shorter than the internodes, elongate inflorescences, a calyculate ovary, basally recurved pods, tan-colored tepals, a cream-yellowish lip with scattered hairs on the disc, and a poorly penicillate callus are characteristic among American vanillas. It differs from other Vanilla species, in that several populations are found in mountain habitats up to 1700 m elevation. Molecular data suggest that it is the sister species of all the American penicillate vanillas. This species is widely known as V. wrightii, a synonym; however, its identity was first elucidated by Sarah Thomas, from Kew and Eric Christenson published a well illustrated paper on the correct identity of this species."
