Internode disconnection greatly decreased further internode elongation but increased specific internode length. 实验过程中的节间切断处理抑制了节间的进一步伸长但提高了比节间长度。
This is a distinctive species with remarkably short leaf sheaths, exposing long lengths of internode, and a small, stiff panicle of horizontally tiered branches. 这非常一特别种具短叶鞘，暴露长节间的长度，以及一种水平层层排列的分枝的小，硬的圆锥花序。
