long, generally with four to nine or ten spikes. Some spikes get no 
farther than the floral stage. On others from three to six nutlets 
ripen, part of the flowers on them being aborted. One stem with 
eleven spikes in various stages of development had seven with perlet 
fruit, though not fully grown in all, aggregating about twenty-ie 
nutlets. The largest number on a single spike is six. The spikesat _ 
2-3™ long, on slender diverging or erect-spreading grooved and 
angled peduncles, which are 3-7 (mostly 3-4™) long. The autlets 
are 3-4™ long by 2.5-3™" wide. They are brown to reddish-bromit — 
color, the surface minutely roughened under a lens. They are thie 
keeled on the back, the prominent middle keel having a thin, shap — 
slightly angled margin. There is a shallow central depression on each 
side, circular, or a little elongated longitudinally, with a diamete 
about one-third that of the body of the nutlet. The plants grew ® 
shallow water, the upper parts of the inflorescence usually protruding 
above the surface. I am indebted to Mrs. Agnes Chase of Chicago for 
the drawings, which faithfully represent the specimens.— E. J. Hlth
