Eragrostis paupera, a native grass, is truly a dwarf. It can produce seed as little more than a sprout. Large plants are seldom more than a few inches tall or wide. It can be found abundantly on the runway but is rare elsewhere except due to out planting.
Young sprouts of E. paupera are characterized by opposite curled leaves, with early leaves often withering to a brown sheath from which later leaves grow. See the Poa annua section for comparative photos of those to plants as sprouts. At this stage, they are very similar to Fimbristylis.
