Morphology General Habit
Loosely tufted annual; culms 15–70 cm. high, often weak and ascending.
Morphology Leaves
Leaf-blades broadly linear, 4–25 cm. long, 4–22 mm. wide.
Morphology Reproductive morphology Inflorescences
Inflorescence of 7–15 racemes, borne on an axis 6–15 cm. long; racemes 2–10 cm. long, often compound, bearing mostly paired distant spikelets spreading from the triquetrous rhachis, the inflorescence imitating a panicle; pedicels or some of them, longer than the spikelets, up to 15 mm. long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets broadly elliptic, 2.5–3.5 mm. long, glabrous to pubescent, acute, with a short stipe up to 0.5 mm. long; lower glume 1/3–1/2 the length of the spikelet; upper glume and lower lemma membranous; upper lemma rugose, subacute to acute.
Habitat
Weedy places in deciduous bushland or margins of riverine forest, often preferring light shade; 0–1500 m.

Morphology General Habit
Annual up to 45 cm. high
Morphology Reproductive morphology Inflorescences
The inflorescence, with its distant spikelets and long pedicels, simulates a panicle, and the plant is commonly mistaken for a species of Panicum
Ecology
A weed of cultivated land and disturbed soils.

Morphology General Habit
Annual; caespitose. Culms geniculately ascending; weak; 15-70 cm long. Ligule a fringe of hairs. Leaf-blades 4-25 cm long; 4-22 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 7-15; borne along a central axis; unilateral; 2-10 cm long; simple, or secondarily branched. Central inflorescence axis 6-15 cm long. Rhachis wingless; angular. Spikelet packing adaxial; distant; irregular. Spikelets spreading; in pairs. Fertile spikelets pedicelled. Pedicels filiform; unequal; 3-15 mm long; 1.1-4 length of fertile spikelet.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; acute; 2.5-3.5 mm long; falling entire. Spikelet callus square; 0.2-0.5 mm long.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; acute; 2.5-3.5 mm long; falling entire. Spikelet callus square; 0.2-0.5 mm long.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; clasping; 0.33-0.5 length of spikelet; membranous; without keels; 5-7 -veined. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 7 -veined. Upper glume surface glabrous, or pubescent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 5 -veined; glabrous, or pubescent; acute. Fertile lemma ovate; 2-3 mm long; indurate; without keel. Lemma surface rugose. Lemma margins involute. Lemma apex acute. Palea involute; indurate; without keels.
