What term describes earlike extensions at the base of a grass leaf blade around the shoot?

Explanation:
Auricles are ear‑like extensions at the base of the leaf blade that wrap around the shoot, helping anchor the leaf to the stem as the plant grows. This feature is distinctive to grasses and varies among species. The ligule is a small membrane or fringe at the junction between blade and sheath, not wrapping around the stem. The sheath is the tubular part that encases the stem, and the leaf blade is the flat, photosynthetic part of the leaf. So the ear-like base around the shoot is auricles.
