The flower-head is a dense spray. As the flower dries the awns may become tangled to form a hairy mass.
1: Lemma. The hairs on the awn are more 1mm to 2mm long. 2: Patch of Supple Spear-grass at Maldon. 3: Dense tangled flower head. Kalimna reserve. 4. Glumes (lower left) and lemmas. The awns are twice-bent.
