The highly specialized stilt-root palm Socratea exorrhiza lacks an acaulescent establishment phase and is able to elevate itself in shade at the young stage with minimal investment in trunk building, progressively consolidating its architecture with increasing energy availability while reaching higher understory strata (Hogan, 1986).
Numerous species are massive palms forming dense stands and they are therefore remarkable elements of the landscape, but there are also smaller acaulescent species in both forests and savannas.

In this species, spear leaves were cut from large, acaulescent juveniles without causing any immediate damage, but since the number of leaves harvested per year was the same as the number of leaves produced, palms eventually died, as a consequence of the lack of leaf replacement.
