The node is the swollen part of the stem that marks the place of leaf attachment. The internode is the region between each node. The leaf is further divided into an upper part, the blade, and a lower part, the sheath. The collar may be a different shade, broad, or narrow. The sheath is split, partially split with overlapping margins, or closed.
Auricles are either long, short, or absent.
This is a term that describes how the new blade grows from the sheath. Vernation is either rolled or folded. Roots of turfgrasses are typically fibrous, many branched, and shallow as compared to other plants. Grasses have a subapical meristem- a growing region that is located below the tip of the plant. This is why grasses can be mowed without damaging the plant s ability to grow normally.
