1a. Branches of panicle each with 20–130 spikelets [Fig. 193], persistent, the branch axis terminated by progressively reduced spikelets, not prolonged beyond spikelets; disarticulation above the glumes
1b. Branches of panicle each with (1–) 2–8 (–15) spikelets, deciduous, the branch axis not terminated by reduced florets, the axis prolonged beyond the base of the uppermost spikelet as a bristle 3–6 mm long; disarticulation occurring at base of branch
3b. Inflorescence with (3–) 6–12 branches; central awn of lowest lemma arising from between two membranous lobes 0.5–1.5 mm long (i.e., the lemma with 5 total lobes; the lateral lobes sometimes shorter in B. repens)
