    TYPE: frequent on rocks in stream bed, right fork of Cano Yutaje at 1500 m alt., Cerro Yutaje, Serrania Yutaje5 Rib Manapiare, Amazonas, Venezuela, February 21, 1953, B. & C. K. Maguire 35374.

    Apparently Vriesia sulcata is most nearly related to V. chrysostacbys E. Morr., but its much larger bracts and flowers and its exposed geniculate rhachis make the differences much more obvious than the similarities. Since the type and only specimen is at anthesis, there is also the possibility of relation to some species where the flowers become secund later, such as V. vexillata L. B. Smith. This latter, however, has a lax inflorescence and sepals that exceed the floral bracts.
