The Trifolium arvenfe, though not to be found in every walk that one takes about London, is common enough 
in fandy, and gravelly foils, and in light arable lands, which it chiefly affects; we have obferved it moft fre- 
quently about Charlton ; in the fand pits behind the Church it may be found with certainty. 
There is fcarcely any tribe of plants which vary more in their inflorefcence than the Trefoils (fee the feveral 
fpecies figured in this work) the arven/é differs remarkably from all our others, the flowers growing in foft, 
oblong, hairy heads, of a light colour, which have a moft pleafing appearance, and render the plant very 
confpicuous, it.is from thefe, as is well known, it has very generally acquired the name of Hares-Foot. 
From what we have obferved, the feeds in many of the fpecies of this genus are not fcattered abroad as in 
- moft of the leguminous plants, but vegetate in the heads as they lie on the ground; we have noticed this economy 
in the prefent as well as other fpecies ; how far the whole genus is fubject to it deferves inquiry.
