Sorry, no etymologies found.
The _Melocacti_ are distinguished by the distinct cephalium or crown which bears the flowers.
The plants are nearly allied to _Cereus_, differing chiefly in the floriferous portion developing these longer and more attenuated hair-like spines, which surround the base of the flowers and form a dense woolly head or cephalium.
