The Genus S1ipuium contains fourteen or fifteen species, — 
mostly of a stately character, all inhabitants of North Ame-_ 
rica and in general confined to the Southern States. Very 
few of them are yet figured, and the greater part of them 
are scarcely known to the European Botanists, save through

together with the S. connatum and S. laciniatum may be 
reckoned among the tallest of the Composirz which inhabit 
the Prairies of the Southern United States. They are how-

which yielded the Laser of the Romans, a kind of gum, but which seems 
to have no connection with the present Genus.
