• DESCRIPTION
A genus of plants usually treelike and branched, with ribbed cylindrical stems, candelabra like or columnar, some
having the characteristics of a trunk densely covered with spines while the reproductive stems lack them.

bent back and covered with scales, white, creamy-white to orange red, pollinated by bats (Platalina genovensium)

ripe, having deciduous scales. Seeds variable, usually ovoid, sometimes wrinkled, shiny, brownish black, dispersed by bats (Platalina genovensium) and birds (Phyllotis darwinii).
