lichens on the borders of ponds. (C. rigida, ft. Carey; but differs in its fruit, 

 glume, loose spikes, Ivs. &c.)

 late ; pe'rig. subglobous, obtuse, entire at the mouth, a little greater than the ovate, 

 subacute glume; st. a foot high, triquetrous, leafy at the base; Ivs. shorter than

 flowered; perig. ovate-oblong, subtriquetrous, subinflated, obtuse or acutish, entire
