The joints, like all other parts of the plant, are beset with numerous inch-long spines, and many of them fasten in the loose, moist soil and strike root.

In this way many new plants are formed, standing in a circle around the mother plant.

On sloping ground the young plants form rows, some forty feet long.

There was a fruit to be observed, but very scarce in comparison with that of other species of _Cereus_ growing in the vicinity..
