Derivation
Digitaria Haller, Hist. Stirp. Helv. 2: 244 (1768). From the Latin digitus (finger), alluding to radiating inflorescence branches.

aequiglumis- from the Latin aequus (equal) and gluma (husk). Glumes sub-equal.

Habit
Annual. Stolons present. Culms erect or geniculately ascending or decumbent, 20–50 cm tall, 2–5-noded, without nodal roots or rooting from lower nodes. Mid-culm internodes glabrous. Mid-culm nodes purple, glabrous. Lateral branches sparsely branched or branched. Leaf-sheaths glabrous on surface. Leaf-sheath auricles present. Ligule an eciliate membrane, 1–2 mm long, truncate. Leaf-blades flat, 2.5–11.5 cm long, 2–5 mm wide. Leaf-blade surface smooth, glabrous or pubescent. Leaf-blade margins smooth. Leaf-blade apex acuminate.

Inflorescence
Inflorescence digitate, with racemose branches, exserted or embraced at base by subtending leaf. Racemes 3–5, erect or ascending, flexuous, unilateral, 5–8 cm long. Central inflorescence axis 0–2.5 cm long. Rhachis narrowly winged, angular. Spikelet packing imbricate.

Spikelets
Spikelets in pairs. Pedicels 0.3–0.5 mm long, scabrous, tip rectangular. Fertile spikelets 2-flowered, comprising 1 fertile floret, lower floret sterile, upper fertile, without rhachilla extension, lanceolate, dorsally compressed, acuminate, 3–3.7 mm long, falling entire.

Glumes
Glume 1 (the lower absent or obscure), thinner than fertile lemma. Upper glume elliptic, dorsally convex in profile, 3–3.7 mm long, 100% of length of spikelet, membranous, 5–7-nerved. Upper glume surface pubescent, hairy between nerves. Upper glume apex acute.

Florets
Basal sterile floret 1, without significant palea. Lemma of lower sterile floret elliptic, 3–3.7 mm long, 100% of length of spikelet, membranous, 5–7-nerved, with equidistant nerves, with nerves free at apex, smooth, pubescent, hairy between nerves or between nerves but central interspaces glabrous, acute. Fertile lemma elliptic or oblong, 2.5–3.5 mm long, cartilaginous, much thinner on margins, pallid. Lemma margins flat, covering most of palea. Lemma apex acute or apiculate. Palea cartilaginous.
