L 68° 57.92', 12°10.71') The high northern escarpment of Seroe Spelonk (70.4 meters) is excavated into spaceous caves, with enormous stalactites pendant from their roofs (fig. v-13). At Landhuis Hato, one of the only permanent streams on the islands issues from a cave. The nearly level terrane near the base of these cliffs supports a luxuriant growth of brush, and the densest stands of Cereus that I have ever seen.
This taxon was proposed as a form of Cerion uva uva.
Baker (1925:42) noted that "mean diameter of specimens from the type locality of Cerion uva diablensis falls outside the total range of variation in individuals of the type locality of Cerion uva hatoensis."
