Griffithsochloa multifida

HABIT Perennial; caespitose. Culms erect, or decumbent; 15–40 cm long. Culm-nodes pubescent. Ligule a ciliolate membrane; 0.5 mm long. Leaf-blades 2.5–8 cm long; 1–1.5 mm wide. Leaf-blade surface ribbed. Leaf-blade margins tuberculate-ciliate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 5–10; borne along a central axis; cuneate; 0.3–0.4 cm long; bearing a triad of spikelets. Central inflorescence axis 3–6 cm long; tip subulate. Rhachis deciduous from axis; terminating in a barren extension; extension bristle-like (1.5–2mm, ciliate). Raceme-bases linear; 0.5–1 mm long; persistent.

Spikelets in threes. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets sessile; 2 in the cluster.

STERILE SPIKELETS Companion sterile spikelets well-developed; male; cuneate; laterally compressed; 2.5–3 mm long; shorter than fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; pilose; acuminate. Companion sterile spikelet lemmas 2; several-awned (5 awns).

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3–4 mm long; falling entire; deciduous with accessory branch structures.

GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume linear; 2 mm long; 0.6 length of upper glume. Lower glume surface pilose. Lower glume apex acuminate. Upper glume lanceolate; 2.5–3 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface pilose. Upper glume apex dentate; 2 -fid; awned; 1 -awned. Upper glume awn 0.5–1 mm long.

FLORETS Fertile lemma elliptic; 3 mm long; cartilaginous; without keel; 3 -veined. Lemma margins ciliolate. Lemma apex lobed; 3 -fid; with simple equal lobes and with central lobe bidentate; with lanceolate lobes; incised 0.33 of lemma length; mucronate (from sinus). Apical sterile florets 2 in number; barren; in a clump; oblong; 1–2.5 mm long. Apical sterile lemmas awned; 5 -awned. Apical sterile lemma awns 2–3 mm long; 10 per spikelet in number.

DISTRIBUTION North America: Mexico.
