Ranunculus pedatifidus, Smith in Rees. Cyclop. No. 72 (1819). 
R. affinis, R. Br. in Bot. App. Parry’s First Voyage, 
265 (1823). 
Smith gives a very good account of the plant, saying that 
there are four specimens of it in the Linnzean Herbarium, and that 
it is a native of Siberia. It is now known to inhabit both north- 
ern Asia and North America. The specimens are still in the 
Linnzean Herbarium. 
Var. CARDIOPHYLLUS (Hook.), (2X. cardtophylius, Hook, FI. 
Bor. Am. i. 14 (1830) ; &. affints, var. cardiophyllus, A. Gray, Proc. 
Acad. Phil. 1863, 56), the state of the species with entire or nearly 
entire radical leaves, appears to bear a similar relation to it as A. 
micranthus, Nutt. does to R. abortivus, L. 
RANUNCULUS GRAYI. 
Ranunculus pedatifidus, Hook. Fl. Bor. Am, i. 18 (1830), 
not of Smith (1819). 
R. Hookeri, Regel, Fl. Ost. Sib. i. 47 (1862), not of Schlecht. 
Linnza, ix. 610 (1834). 
Schlechtendahl’s &. Hookeri isa Mexican species. 
IsOPYRUM, L. Gen. Pl. Ed. 2, 245 (1742). 
Coptis, Salisb. Trans, Linn. Soc. viii. 305 (1803). 
Tsopyrum and Coptis have been kept separate by recent au- 
thors, the character depended upon for their distinction being the 
sessile follicles of the one and the stipitate follicles of the other. 
Baillon (Hist. Pl. i.) has referred Coptis to Helleborus, L, under 
which genus the typical species 17. ¢vifolius, L. was first described, 
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 Coftis with Jsopyrum. 
Tsopyrum stipitatum, A. Gray, of the Northwest contains m itself 
the characters of the two genera. Our Eastern species He/leborus 
trifolius, L., will then become I. TRIFOLIUM (L).
