| You also need to see if there is a ligule, which is the fringe of tissue on the leaf blade where it folds away from the stem. |
| Often they are much like ordinary ray flowers, except that there are two small teeth at the top of the corolla tube, opposite the ligule. |
| To be measured from the ligule to the tip of the flag leaf on the longest stem. |
| Many groups have a ligule or small flap of tissue adaxially above each microphyll, or its homologous sporophyll. |
| Molinia also has a tuft of hairs instead of a ligule, and a split sheath, and its habit is different. |
| Ray florets are much larger, with an 8-12 mm long, yellow, three-lobed, strap-shaped ligule surmounting a short corolla tube. |
