Editing Astrocaryum aculeatissimum (section)

===Description:===
A moderately sized clustering palm with slender, spiny trunks,
and slightly arching, flat leaves that are grayish below.
The trunks are covered by rings of very sharp spines,
believed by some biologists to have evolved as protection against
the extinct Megatherium Giant Ground Sloth.
It has large, attractive, lightly spined, orange-brown fruits.
