 field, Herkimer county. These are localities without inlet or outlet, and have 

 no connection with streams either northward or southward, on the summits 

 of our highest hills : remarkable for a plant usually occurring along the 

 largest streams and Lake shores. 



Also frequent in southern Oneida county and the adjacent parts of Otsego 

 and Madison counties, Gray. 



To Ranunculus aquatilis, var. divaricatus, the range : 



Abundant in the inlets and bays of Lake Ontario, from Oswego to Brad- 

 dock's bay, Monroe county. 



To R. purshii : 



This species received the name R. lacuslris from L.C.Beck and J. G. 

 Tracy a little earlier than the present one from Richardson. This was given 

 in the second edition of Flora of the Polar regions, of which the first edition 

 was published in 1823. 



One of the first papers read before the Albany Lyceum of Natural History 

 was a description of this new species of Ranunculus; which afterward was 

 published in the New- York Medical and Physical Journal for January 1823, 

 as follows : 



Ranunculus lacustris. Leaves all submerged, alternate, dichoto- 

 mously divided into numerous capillary segments ; with clasping mem- 

 branaceous stipules. Peduncles emerging, dichotomous, slightly furrowed. 

 Flowers terminal, large. Calyx spreading, hairy, fleshy, caducous. Petals 

 five to eight, obovate, larger than the leaves ot the calyx, and larger than 

 those of R. bulbosus. Nectary petal-like, cucullate-tubular, nearly equal- 

 ling the length of the filaments. Fruit oval. Stem floating, branched, gla- 

 brous, hollow, round, from two to four feet in length, extending radical 

 fibres from the lower joints. Roots fibrous, short. 



Habitat. In a stagnant pond near Lansingburgh on the Hudson river, and 

 in a similar situation near Lewiston on the Niagara. 



On the appearance of Hooker's Flora Boreali .Americana, which adopted 

 R. purshii, these gentlemen reaffirmed their name, with another description 

 and a plate, in the Transactions of the Albany Institute. 



The plant also occurs in marshes east of Onondaga lake, and along the 

 shore of Lake Ontario. In Sodus bay, it grows high on a sandy point, and 

 changes its character for the place, having a creeping underground rootstalk, 

 sending up erect stems bearing two to four petioled leaves, which are nearly 

 half an inch broad and twice notched at the end, or the highest sessile, ob- 

 ovate, entire.
