State. The rant^e of tlie 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 R. fascicu/ari-i than to li. se/)le)ilrionalif<. 



4. Ranunculus fasciculaeis Mulil. Cat. 54 (1813); Bigel. Fl- 

 Bost. 137 (1814). 



A strongly-marked species capitally figured l)oth by Hooker, 

 (Fi. Bor. Am. i. t. 8), and Gray, (Gen. 111. 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, etc., and has a cluster of thick, fleshy roots, like 

 those of R. hirsiUus. 



I have not seen the type of this species but it was examined 

 by either Dr. Torrey or Dr. Gray, as is indicated in their Flora 

 of N. A. 



5. Ranunculus septenteionalis Poir, in Lam, Encycl. vi. 125 

 (1804). 



I am following Dr. Gi'ay, (Proc. Am. Acad. xxi. 37G) in 

 apjilying tliis 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 B. 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 Avith (he species by Dr. Gray, and has 

 twelve pages ]iriority of place in ]iul)lication. 



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 B. hi.'<pi(hii<, Michx. It is 

 often entirely glabrous, sometimes pubescent, is much stronger 

 in growth and has larger leaves than B. hifipidus, with acute, 

 sharply incised or serrate segn^ents; the flowers are often more 

 than an inch broad ; the achenes are strikingly ditferent being 

 oblong, with broad, often thick margins, and the beak is stout,
