Apurau is a densely tufted plant, growing up to 20 to 50 centimeters high. Stems are rather spongy, terete, leafless, and when dry, often transversely septate. Spikelets are 7 to 30, crowded, ovoid to oblong, 1 centimeter long or less. Glumes are ovate, about 4 millimeters long. Nuts are 3-angled, black and shining, obovoid, about 2 millimeters long. Hypogynous bristles are absent.

– In open, wet places in settled areas at a low altitude in Luzon Provinces of Cagayan, Ilocos Norte, Pangasinan, Nueva Ecija, Rizal and Laguna.
– Also occurs in the Old World tropics.

Considered purgative.

Parts used
Whole plant.

– In India, plant is used as a purgative.
– In the Jaipur district, used for vomiting.
– In Bangladesh, roots and branches used for baby’s vomiting and diarrhea. The juice from well-grounded roots given to babies before breakfast.

Study Findings
Nutrient Removal Potential: Study evaluated the nutrient removal capacity of Lemna major (floating macrophyte) was compared with Scirpus articulatus (emergent macrophyte) in hypertrophic mesocosms held in situ.
