T. arguens has white fibrous roots. Stems upright or somewhat lying, cylindrical, slippery, small, long, segmented, dense reed, reddish purple or sometimes yellowish or green and brown when dry.
Compound flowers are arranged in clusters at the ends or in the armpits, grains are protected by a lancet-shaped sheath, 2.5-3.5 cm long and purplish green. Androgynous flowers have 4 ears, 3 stamens and 2 pistil heads.
Elliptical fruit, almost round piston, solid hair, 8-10 mm, green and deciduous with a stalk. Seeds are round, small and black. This species has two varieties, Themeda arguens var. arguens and Themeda arguens var. balinensis.
Merakan feels fertile in open places, lots of sun and dry. Group in savanna forests, teak forests, secondary forests, road sides and dykes. Grows on various types of soil including clay and lime at altitudes up to 1,200 m.
