huitztli (Mdz39r)
For huitztli (39r), here is a Glyph description: This element for a thorn or spine (huitztli) has been carved from the compound glyph for the place name Huitzamolla.
Stephanie Wood
The huitztli probably comes from the tip of a maguey leaf. It looks much other spines or thorns in the Codex Mendoza. Because these spines were used for self-sacrificial blood-letting, the red color may suggest blood.
