before me, and that in size and form these seeds, as well as 
the flowers, anthers and capsules, are intermediate between 
ose of the supposed parents, while the number of stamens 
is that of J. effusus. The panicle is remarkably compact, 
and consists of 10-15 secondary branches of nearly equal length. 
-EFFusvs, Lin., is found from Maine to the Rio Grande 
nearly equal length with the filaments. The most tie pei 
and very constant character consists in an number of sta- 
mens and in the obovate or even clavate, upwards sino 
tricoccous, retuse capsule ; seeds per Bop a finely lineolate.
