Porous in texture and low in exchangeable bases, these silicious podzolic soils sustain a slightly-dwarfed evergreen restinga forest, of which piassava is a common member Silva and Vinha List of Attalea species.
In the midstory palm Attalea funifera female sex expression is favored by smaller and fewer neighboring trees, a pattern that probably reflects light limitation, because the cost of producing a female infructescence relative to a male inflorescence is Photo by Dennis Johnson.

Funifeta, Bondar and Valeriano attributed the luxuriant post-fire carpet of piassava seedlings to the stimulation of long-dormant seeds by the heat of the sun, whereas Moraes speculated that the heat of the fire directly induced germination. Sousa ; Hooker
