The name of Hop Trefoil has been with much propriety beftowed on this plant, as the little heads formed by the 

 flowers are larger and more refembling the hop than thofe of any of the other fpecies. 



We are carefully to diftinguifh it from the Trijolium procumbens, than which it is in every refpecl larger, and lefs 

 procumbent. 



It is by no means an uncommon plant in dry paftures, on the borders of fields, and in gravelly foils ; in fome 

 fields I have obferved it naturally to form a confiderable part of the Farmers crop, which though a fmall one was 

 judged to make excellent fodder. 



It is perhaps one of thofe plants which merits the further attention of the Hufbandman. 

 June and July are the months in which it ufually flowers, 



Scopoli doubts, and apparently with great propriety, whether the lrifolium fpadiceum of Linnjeus be a fpecies 

 diftinot from this.
