R. Br. Ex R. & S. are composed of 3-7 spikelets in a spatheate spike. The spikelets have two florets. All of them are male, except that the basal spikelet has a bisexual upper floret and a male lower floret. A comparative study on the upper florets of the bisexual and male spikelet by SEM showed that the arrest of the development of gynoecium causes the maleness of the upper florets. %M doi:10.6165/tai.1998.43(3).235
