Notes for the Genus:
Weberocereus
Etymology - Named in honor of Frederic Albert Constant Weber - a cactus enthusiast of the 1800's.
Most of the epiphytic "jungle" cacti genera have at least a few members which are common in cultivation. This is not so with the genus Weberocereus, where only a few specimens can be found in cultivation grown by an occasional collector with an interest in the uncommon. In the wild, the species are found in primarily in Central America with limited extend up into Mexico and down into Ecuador.
The plants are vine-like clamoring, putting out areal roots as they grow. Stems are segmented and round, angled, or flattened. Areoles are small and spines few or absent. The flowers are nocturnal, funnel-shaped mostly white, with some pinkish or yellowish.
