Lower glume of sessile spikelet pitted between veins.

在脉之间具洼点的无梗小穗的更低的颖片。

Culms up to 1. 5 m; upper glume of sessile spikelet thinly pilose.

The length of the lower glume is very variable, even within a single raceme.

更低的颖片的长度非常易变，即使在一单个的总状花序内。

This is formed by the swollen lowest rachilla internode and adnate lower glume.

膨胀的最低的小穗轴节间和贴生的更低的颖片形成这。

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。
