This species, the R. aquatilis of English Botany, Batrachium 
heterophyllum (Prodromus Fi. Batav), is plentifully distributed in 
all the districts throughout the county, but less so on elevated 
ground. When the floating leaves are not produced, but are all 
multified and setaceous, it is the R. aquatilis var. pantothrix Fries, 
the plant being similar in all other respects. Both states are fre- 
quently to be found in the same place. In swift streams it some- 
times much resembles “ R. flwitans” (Lam.) Flor. Fr. iii. 84. Reich. 
Icones, iii. t. 2. Engl. Bot. Suppl. t. 2870: (a plant, sufficiently dis- 
tinguished by the structure of its whip-shaped leaves, but which 
has not as yet been noticed in this county), and forms a tran- 
sient but very elegant ornament of our rivers and brooks during 
the month of June, copiously expanding its large pure white 
blossoms, and gracefully undulating its bright green elongated 
stems, and hair-like leaves, in the rapid and shallow currents, strik- 
ingly reminding us-of the “tresses fair” of Sabrina, alluded to in 
Milton’s Comus :— 
“« Sabrina fair, 
Listen where thou art sitting 
Under the glassy, cool, translucent wave, 
In twisted braids of lilies knitting 
The loose train of thy amber dropping hair.” 
The R. peltatus, (Fr.) R. floribundus, (Bab.) R. trichophyllus, 
(Chaix) and R. Drouetii, (F. Schultz,) have not as yet been ob- 
served in the county. Those students who are interested in the 
study of these “ Batrachian Ranunculi,’ I would refer to Mr. 
Charles C. Babington’s excellent paper in the “Annals and Maga- 
zine of Natural History,” for December, 1855.

with floating leaves). Engl. Bot. Suppl. t. 2869. Reich. Icones,
