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.
