Auricles are either...

Explanation:
Auricles are ear-like projections at the base of a grass leaf where the blade meets the sheath. They vary across species: in some grasses they are absent, in others they clasp or wrap around the stem to help anchor the leaf, and in some the base of the leaf has a fringe of hairs forming the auricle. This range of forms is why all of the above describes the possible appearances, and why it’s the best answer.
