The New World tropical epiphytic orchidProsthechea trullais often confused with Prosthecheacochleata (syn.Encyclia lancifolia). There is confusion in the literature involving these two species -- some plants in the trade were erroneously identified as Encyclia lancifolia instead ofProsthechea trulla.They are similar in look, but P. trulla has a narrower lip (9-17 mm wide and 9-12 mm long) with a trowel shape, whereas the lip of P. cochleata is broader (13-26 mm wide and 10-21 mm long) and the sepals and petals of P. cochleata are longer (30-75 mm in length) than those of P. trulla.
