S. occidentalis is distinguished from S. validus by achenes ^ 

 larger, by scales ^ — ^ longer than the achene and nearly 

 twice as long as the scales of S. validus, viscid-pubescent, 

 overlapping % their length or more ; by the cylindric more 

 densely fruited spikelets in capitate clusters ; and by the 

 denser umbels and harder culms. 



SciRPUS heteroch^tus, Chase, Rhodora, vi : 70. 



Distinguished from S. validus and S. occidentalis by the 

 3-cleft style, by the triquetrous achene, by the fragile bristles, 

 fewer and shorter. An apparently rare species in the United 

 States and not yet recorded from Canada. Mr. Ezra Brainerd 

 found the three species growing in Lake Champlain where S. 

 occidentalis begins to ripen seeds about six weeks later than 

 S. validus ; S. heterochcetus flowers there at a date midway be- 

 tween the two.
