| Identification | Common Carpetgrass is more-or-less mat-forming from slender horizontal rhizomes. The slender stems grow erect, 1-2 feet tall (where not mown), topped by an inflorescence of 2 ascending to spreading, slender branches, with spikelets tightly pressed to the branches. Sometimes also it has an additional inflorescence from a leaf axil lower down on the stem. Axonopus furcatus is very similar but it has spikelets that are 3.5-5.5 mm long (vs. 1.6-2.8 mm long in A. fissifolius). | |
| Taxonomic Comments | A synonym is A. affinis Chase.
