Stenia is a genus in the orchid family (Orchidaceae). It was established by John Lindley in 1837. These epiphytic plants occur in warm, humid habitats of Trinidad and the Amazonian slope of the northern Andean region in South America.
Stenia plants produce a short, creeping or erect, single-flowered inflorescences, growing laterally. The flowers are medium-sized, with equal petals and sepals. All members of this genus have their flowers dominated by the large, shoe-like, concave labellum (lip) with a disc-like, toothed crest. The flowers have four elongate pollinia, with the upper pollinia long and narrow. They occur at any time of the year, though slightly more concentrated during summer in cultivation.
