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

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

 denser umbels and harder culms.

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

 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 d^te midway be- 

 tween the two.
