General Plant Info
Acacia cornigera or Vachellia cornigera, commonly known as Bullhorn Acacia (family Fabaceae), is a swollen-thorn tree native to Mexico and Central America. The common name of "bullhorn" refers to the enlarged, hollowed-out, swollen thorns (technically called stipular spines) that occur in pairs at the base of leaves, and resemble the horns of a steer. In Yucatán (one region where the bullhorn acacia thrives) it is called "subín", in Panamá the locals call them "cachito" (little horn). The tree grows to a height of Template:Convert.
May be psychoactive, as the root is used as an aphrodisiac, and may have been added to the Central American balché beverage. Claims of tryptamines in this species might be speculation. Research needed.
