| Grain is sub-globose, oblong or trigonous, closely invested by the glume and its palea. |
| Each floret is enclosed in a lemma and palea and all florets produce two lodicules, three stamens, and a gynoecium. |
| A conspicuous tuft of fine silky hairs, longer than the palea at the base and on the rachilla. |
| Each flower has a lemma and a palea at its base, and contains two lodicules and one pistil surrounded by three anthers. |
| The lemma and palea surround and protect the flower, and all three of these structures form the floret. |
| Germ tubes arise from secondary sporidia and grow towards stomatal openings of the glume, lemma or palea where they enter. |
