    Delgadillo and Cardenas (1989) reported D. lindigiana Hampe from Chiapas (Cima del Cerro Mozotal, 2970 m alt., Cardenas & Delgadillo 2974, MEXU). This species differs from D. stenophylla in its larger size (stems up to 5 cm in length) and leaves with cells linear throughout and more narrowly bordered (only 4-5 rows wide at base). The species has been collected elsewhere in Costa Rica, Colombia, and Ecuador.
