颖片和外稃短柔毛或者全部具短硬毛。
在脉之间具洼点的无梗小穗的更低的颖片。
膨胀的最低的小穗轴节间和贴生的更低的颖片形成这。
This is formed by the swollen lowest rachilla internode and adnate lower glume.
秆可达1。5米；稀疏的无梗小穗的上面颖片具柔毛。
Culms up to 1. 5 m; upper glume of sessile spikelet thinly pilose.
更低的颖片的长度非常易变，即使在一单个的总状花序内。
The length of the lower glume is very variable, even within a single raceme.
本文还讨论了颖片、芒中的抑制物质及温度对穗发芽的影响。
Temperature influenced preharvest sprouting to some extent. The inhibiting substance in seed coat and ear was also discussed.
小穗对的花梗等于，倍于轴节间；上面颖片具0。5 - 1毫米短尖头。
Pedicels of spikelet pair equal, as long as rachis internode; upper glume with 0. 5-1 mm mucro.
小穗对的花梗等于，倍于轴节间；上面颖片具0。5 - 1毫米短尖头。
