ISOPYRUM, L. Gen. PL Ed. 2, 245 (1742).
Coptis, Salisb. Trans. Linn. .Soc. viii. 305 (1803).
Isopyrum and Coptis have been kept separate by recent au-l
thors, the character depended upon for their distinction being the
sessile follicles of the one and the stipitate follicles of the other.
Baillon (Hist. PI. i.) has referred Coptis to Helleborus, L. under
which genus tjje typical species H. trifolius, L. was first described,1
and except for the vegetative characters it is certainly closely re-
lated to this genus. But taking all the known species together
it seems to me more desirable to unite Coptis with Isopyrum.
Isopyrum stipitatum, A. Gray, of the Northwest contains in itself
the characters of the two genera. Our Eastern species Helleborus
trifolius, L., will then become I. TRIFOLIUM (L).
