State. The range of the species appears to be from Ontario to 
Georgia, west to Michigan, the north-west territory and appar- 
ently to Texas. In my opinion this species is more nearly re- 
lated to Ff. fascicularis than to R. seplentrionalis. 
4, Ranuncutus rascicutaris Muhl, Cat. 54 (1813); Bigel, Fl. 
Bost. 137 (1814). 
A strongly-marked species capitally figured both by Hooker, 
(Fl. Bor. Am. i. t. 8), and Gray, (Gen. Ill. i. t. 9)., characterized 
by oblong or linear oblong obtuse lobes to the mostly pinnately 
divided leaves, the lobes of the earliest leaves much broader 
than those of the subsequent ones. The achenes are lenticular, 
closely resembling those of the preceding species, but are 
scarcely margined, and tipped with a subulate style of nearly 
or quite their length. The plant begins to bloom in the Middle 
States (Lancaster, Penn., Small) early in April. It grows on 
dry hillsides, ete., and has a cluster of thick, fleshy roots, like 
those of R. hirsutus. 
I have not seen the type of this species but it was examined 
by either Dr. Torrey or Dr. Gray, as is indicated in therr Flora 
Gf NA. 
5. Ranuncunus seprenrrionatts Poir, in Lam. Encyel. vi. 125 
(1804). 
I am following Dr. Gray, (Pree. Am. Acad. xxi. 376) in 
applying this name, guided by his naming of the specimens in 
his own herbarium and in ours, but I have not seen Poiret’s 
type, which ought to be in Lamarck’s herbarium at the Jardin 
des Plantes. Dr. Gray does not say that he has examined it. 
Poiret’s description is not altogether satisfactory, but until just 
what he had shall be absolutely determined, it is as well to use 
this name, although it may be noted that the name P, lucidus, 
Poir., (loc. cit. 113), a species based on a cultivated plant of the 
Paris Garden and supposed by the author to have come from 
the Levant, is associated with the species by Dr. Gray, and has 
twelve pages priority of place in publication. 
The plant which I have in mind is an inhabitant of ditches, 
swamps and river-shores, is abundantly stoloniferous, some- 
times forming runners two feet long, and about New York 
blooms nearly a month later than &. hispidus, Michx. It is 
often entirely glabrous, sometimes pubescent, is much stronger 
in growth and has larger leaves than &. hispidus, with acute, 
sharply incised or serrate segments; the flowers are often more 
than an inch broad; the achenes are ‘strikingly different being 
oblong, with broad, often thick margins, and the beak is stout,
