forcibly the latter. It differs from S. ciliatum in its more slender 
habit, leaves shorter and proportionately broader, less conspicu- 
ously pointed, petioles ciliate only at the connate base, calyx and 
corolla smaller. The conspicuously ciliate petiole is a remarkably 
constant character in S. ciliafum. Our plant is distinguished from 
S. vadicans by its erect habit, leaves shorter and broader, not 
pointed at base, and by its much larger and more deeply colored 
corolla. The habitat is strikingly different from that of either of 
the two related species. S. ciliatum is a plant of low woods and 
banks of streams, while S. radicans grows is grassy swamps and 
woods along the coast and in the Mississippi Valley.

This plant is certainly sufficiently well characterized to be 
maintained as a species distinct from P. camphorata. It differs 
from the common plant of the Atlantic coast in its taller and —
