Which stem cross-section is characteristic of sedges?

Explanation:
Sedges are best identified by their stem shape when cut across the plant. The hallmark is a triangular cross-section, giving the stem three distinct edges. This feature is so distinctive that the saying “Sedges have edges” is often used to remember it. In contrast, grasses typically have a round or cylindrical cross-section, not triangular, and flat cross-sections aren’t typical for sedges. So the triangular cross-section is the characteristic trait that sets sedges apart.
