 Leaves f stem, i in. broad. Umbel in well-developed examples large, straggling, 

 rays 4-10 up to 9 in. with radioles of secondary umbels up to 3 in., but small 1- 

 headed examples are frequent, with all intermediate forms ; bracts as long as umbel 

 or greatly overtopping it. Spikes large, open, rhachis glabrous. Spikelets 3-16, 

 often 1 by i in,, 20-fld., compressed. Olumes boat-shaped, ovate, obtuse, IT-Il- 

 nerved, in fruit scarcely imbricated ; rhachilla slender, in fruit flexuose, wings oblong 

 hyaline separating. Stamens 3 ; anthers linear-oblong, mutieous. Nut triquetrous, 

 obtuse ; style shorter than nut, slender ; branches linear, slender. 



Sect. 6. Rotundi. Tall or medium plants, stoloniferous or rhizome 

 woody. Leaves and bracts long. Rhachilla of spikelets winged. Glumes 

 closely imbricated. (Sp. 48-55.)
