Plants annual. Culms 30-90 cm, erect or ascending, somewhat compressed;
lower internodes 1.5-2 mm thick. Sheaths conspicuously keeled, margins
often with long, papillose-based hairs, particularly near the throat; ligules
0.2-1 mm, truncate, erose; blades 15-40 cm long, 3-7 mm wide, with prominent,
white midveins, margins and/or adaxial surfaces often with basal papillose-based
hairs. Panicles with 4-10(17) branches, often with 1 branch attached as
much as 3 cm below the terminal cluster; branches (3.5)7-16 cm long, 3-5.5
mm wide, linear. Spikelets 4-7 mm long, 2-3 mm wide, with 5-7 florets,
obliquely attached to the branch axes. Lower glumes 1.1-2.3 mm, 1-veined;
upper glumes 2-2.9 mm; lemmas 2.4-4 mm; paleas with narrowly
winged keels. Seeds ovoid, rugulose and obliquely striate, usually not
exposed at maturity. 2n = 18.
Eleusine indica is a common weed in the warmer regions of the world. In
the Flora region, it usually grows in disturbed areas and lawns, and has
been found in most states of the contiguous United States.
Culms 3-6 dm, branched from the base, spreading or ascending; sheaths papillose-ciliate distally; blades usually smooth; spikes usually 3-8, 4-10 cm נ5 mm, spreading or ascending; spikelets crowded, 3-6-fld; second glume 2-3 mm; lemmas 2.5-4 mm; 2n=18, 36. A common weed in lawns, gardens, and waste places; native of the Old World, now pantropical, extending n. to Mass., S.D., and Utah.
