flat, smooth, or wrinkled. Upper glume lanceolate, 1-keeled above, primary nerve scabrous, apex acute. Florets: basal sterile florets barren, without significant palea;
lemma lanceolate, hyaline, 2-nerved, ciliolate on margins. Fertile lemma lanceolate, hyaline, without keel, apex lobed, bifid, incised 0.5 of lemma length, 1-awned;
principal awn from a sinus, 10 mm long, geniculate, with twisted column, column of lemma awn 3 mm long. Palea absent or minute.
Notes
Found in Africa, China, India, Indo-China, and Malesia. Commonly cultivated and sometimes naturalized, waterlogging not tolerated, often cultivated as a garden
plant, rainfed crop, propagation is by root or plant division, essential oils, flavouring, used in herbal teas, useful for acne and excessive perspiration, muscular pain.
