specifically from rigida ; it is more apt to grow on wet places (whence 
the name Pond- fine) and has longer leaves (occasionally, on strong 
shoots, in fours), and the cones often do remain closed for several years,

often twice as long as in the northern rigida (Wm. H. Ravenel, Aiken, 
S.C.) Prof. Sargent observed it on the mucin and East eae coast, 
but not in West Florida or in Alabama. Felled trees or posts se

leaves and by its cones being often serotinous, more in one tree than in 
ous; young branches green, in the northern form a gaa involucru 
of to to II, in émops of 8 to 9 bracts; cones larger, mostly s sbsenil,
