Note
The specific epithet longitepala refers to the extremely long tepals (sepals and petals) relative to other species of Vanda sect. Cristatae. While Vanda longipetala is clearly related to V. cristata, it differs in the extremely long tepals, slender linear and acuminate lateral petals (length to width ratio of 10 compared with < 6 for V. cristata), and the lack of a constricted base to the column. This relationship with V. cristata is borne out in a recent morphometric study of sect. Cristatae which confirmed that V. longitepala was closely related to V. cristata (Gardiner et al. 2005).
