 The plant is by no means uncommon in Berkshire, and is especially 

 frequent on the muddy margins of ponds and streams in low-lying 

 districts. It is usually glabrous, especially as regards the lower 

 leaves, but a small-flowei'ed plant which grew near Loddon Bridge 

 had the lower leaves pubescent ; the form pubescens, Corb. in Magnier, 

 Scrinia, 1893. In the dry year 1893 R. sceleratus was often much dwarfed 

 (the so-called variety minimus, S. F. Gray, Nat. Arr. ii. 718). In wet 

 years I have seen it almost entirely submerged (the var. suhmersus, 

 S. F. Gray, I.e.) ; in this state the leaves bear much resemblance to 

 those of the Batrachian Ranunculi, with which group this plant forms 

 a link. 



R. sceleratus occurs in all the bordering counties.
