DIGITARIA SANGUINALIS
26. Digitaria sanguinalis (L.) SCOP. Large Crabgrass, Fingergrass.
A low-growing spreading, hairy and pale green annual, bent and often rooting at the nodes; frequently occurring along roadsides, in over-grazed pastures, lawns and gardens.
Leaves rolled in the bud-shoot. Sheath compressed, pilose, green but sometimes purplish-veined, split with margins hyaline. Auricles absent. Collar broad, distinct, sparsely hairy, divided by midrib. Ligule membranous, 0.5 to 2.0 mm. long, acute, undulate or toothed, often reddish. Blade 4 to 10 mm. wide, 5 to 15 cm. long, flat, soft, drooping, often puckered, sharp-pointed, green, not ridged, pilose on both surfaces with a few longer hairs at base on upper surface; midrib prominent on lower surface; margins scabrous.
D. sanguinalis is a stouter-growing grass than D. Ischaemum, is pubescent on the sheaths and blades and generally lacks the purple coloring.
