acuilloxochitl.

The Florentine Codex, Book 11, folios 192r-v, includes images and descriptions of the acuilloxochitl and the cuilloxochitl, which are apparently two ways of naming the same flower. One of the marked features is the way it encircles, "continually spreads in circles," which may resemble writing or painting (note the root "cuil"). The author speaks of spreading the blossoms on the ground, threading and stringing them [which adds another circling dimension]. (Summary by SW.)
