Agrostis clavata

Agrostis clavata, the clubbed bentgrass, is a slender annual or short-lived perennial grass in the Poaceae native to temperate eastern Asia, where it occurs widely in Japan, Korea, China, the Russian Far East, and adjacent Siberia, growing on moist open ground, streambanks, forest edges, and meadow margins. Plants form loose, sparsely tufted bunches 30 to 100 centimetres tall with erect to slightly geniculate culms arising from a fibrous crown. The flat, narrow leaf blades are 5 to 20 centimetres long and 2 to 6 millimetres wide, with smooth sheaths and a short, blunt to slightly pointed membranous ligule. The inflorescence is a delicate, open, broadly pyramidal panicle 10 to 30 centimetres long with whorled, finely scabrous branches that bear small, single-flowered spikelets only towards their tips; the lemmas are awnless and shorter than the lanceolate glumes, with the floret often appearing slightly clubbed in profile. The grain is a small caryopsis.
