Hello everyone, I finally found out the name of the "cohoba" tree I found.
It's called: Cojoba Arborea (L.) Britton & Rose
Common name: frijolillo
Family: Fabaceae
Synonyms: Acacia Arborea, Mimosa Arborea

Cohoba and Yopo
Cohoba, a potent hallucinogen made of ground tree seeds of cojóba tree (Cojoba arborea) , was the mind-altering substance of choice for Taino “behiques” (shamans). The powder was placed on a special carved pedestal and inhaled through a twin-nasal inhaler such as the Y-shaped pipe (also called Cohoba).
Yopo (Anadenanthera peregrina) is similar to cohoba and comes from upper Orinoco, Venezuela and adjacent Brazil. The seeds of these trees are roasted gently and then ground into a fine powder which is mixed with the ashes of certain leaves (alkaline substrate).
