The culms <»f most grasses produ/e branches, especially from the lower nodes near the ground. This branching is j)opularly called tnieriiitj, or stoolinij, or muotiiif/, and is familiar in the case of wheat, oats, and rye, where one kernel not unfrequently produces twenty or more culms. Tillering is favored by shallow, thin seeding. Grasses are generally erect, though some are trail- ing; one or more climb over trees 100 feet Jiigh; others, like Leersia (rice cut-grass), are feeble climbers or sustain themselves on plants by means of numerous hooked prickles on their leaves. Buds are undeveloped leaf or flower branches, and one or more may bo looked for at every node. The apex of the young stem is covered by the young leaves. The nodes are usually swollen or larger than the internodes, but seldom have a length very mucli greater than their diameter. The nodes remain short when the culm is erect, but if by any accident or otherwise the culm is tipped over, the nodes at once become longer on the lower side, and this curves the culm toAvards an erect position. In this way, to some extent, lodged wheat or other grasses can again partially regain their former position. At least, in most cases, the blossoms may be turned up from the ground.
