What is the lower, tubular part of a grass leaf that wraps around the stem?

Explanation:
Grass leaves have a sheath and a blade. The lower, tubular part that wraps around the stem is called the sheath. It encircles the culm and attaches the leaf to the stem. The blade is the flat, extended part you see, with edges called the margin. At the junction of blade and sheath sits a small structure called the ligule, which is not around the stem but marks where the two leaf parts meet. So, the tubular part wrapping the stem is the sheath.
