It
usually stands alone as a single perpendicular column, but is
also found bunched in groups. If it has any branches they are
apt to start at right angles from about the middle of the tree
and curve upward, paralleling the trunk, which form gives it the
appearance of a mammoth candelabrum.
The single saguaro pillar bears a striking resemblance to a
Corinthian column. As everything in art is an attempt to imitate
something in nature, is it possible that Grecian architecture
borrowed its notable pattern from the Gila valley?
Southern Arizona is the natural home and exclusive habitat of
this most singular and interesting plant and is, perhaps, the
only thing growing anywhere that could have suggested the design.
Wherever it grows, it is a conspicuous object on the landscape
and has been appropriately named "The Sentinel of the Desert."
Its mammoth body is supported by a skeleton of wooden ribs, which
are held in position by a mesh of tough fibers that is filled
with a green pulp. Rows of thorns extend its entire length which
are resinous and, if ignited, burn with a bright flame. They are
sometimes set on fire and have been used by the Apaches for
making signals.
