Bermudagrass, probably the best-known of all grasses unless you consider wheat, rice, and corn! |
The leaves of Cynodon dactylon. |
The palm tree (digitate) shape of the seedheads. |

The sawtooth edges of the branches show the tiny spikelets extending downward. |
This view shows that the spikelets are in a double row, a "seed" (spikelet) on each side of the narrow branch. |
Cynodon dactylon is one of the most common lawn grasses. The palm-like seedheads arise from a single point (this arrangement is called digitate). This grass is short, reaching from ankles to knees at most.
The many species of genus Digitaria look a
bit like Bermudagrass, many with narrow branches at the top. However, for the Arizona Digitaria
species, the branches usually extend upwards rather than sideways and do not
extend from a single point (are not digitate).
