context_page_description: A fistula is an abnormal connection between two hollow spaces, such as blood vessels, intestines, or other hollow organs. Fistulas are usually caused by injury or surgery, but they can also result from an infection or inflammation. Fistulas are generally a disease condition, but they may be surgically created for therapeutic reasons.
  In botany, the term is most common in its adjectival forms, where it is used in binomial names to refer to species that are distinguished by hollow or tubular structures. Monarda fistulosa, for example, has tubular flowers; Eutrochium fistulosum has a tubular stem; Allium fistulosum has hollow or tubular leaves, and Acacia seyal ssp. fistula is the subspecies with hollow spines.
