Stalked Crabgrass is an annual grass with stems 0.5-3 ft tall, erect or geniculately rising up. Leaf-blades are 5-15 cm long, 2-5 mm wide. Inflorescence is composed of 3-5 simple or branched racemes arranged along a short common axis 14 cm long; racemes 2.5-11.5 cm long, the spikelets ternate on a triquetrous, wingless rhachis. Sometimes one spikelet is arrested, occasionally the longest flower-stalk branched and bearing 2 spikelets. Flower-stalks are round, smooth, with discoid or cupuliform tip, unequal in length and standing out from the rhachis at maturity. Spikelets are elliptic, oblong-elliptic or oblong-obovate, 1.3-1.75 mm long. Stalked Crabgrass is native to Tropical Asia and China.
