Of the genus Ranunculus there are feveral fpecies which have prickly feeds, but no englifh one in which 
they are fo confpicuoully fo as in the prefent; what a difference in fize and form betwixt thefe and thofe of the 
" Ranunculus fceleratus, plants evidently of the fame genus! 
The Ranunculus arvenfis is a plant common to the corn-fields of moft parts of Europe, but grows more 
abundantly in fome foils than others; it flowers in May and June, and ripens its feeds: in June and July. As 
thefe readily vegetate where they are fpontaneoutly fcattered, this fpecies adds to the lift of the weeds of our 
corn-fields, but not of the moft formidable kind.
