This fpecies of Ervum or 'Tine-Tare is found in moft Corn-fields, often to the Farmers forrow, as it frequent- 

 ly proves very injurious to the Corn, laying hold of it by means of its tendrils, and if the feafon favours its 

 growth quite overcoming it. Like moft plants of this kind it is exceedingly fertile ; on one plant which I cafually 

 pulled up, I counted 220 pods, and as each pod contains four feeds, there muft have been from a fingle feed the 

 amazing produce of 880. 



At firft fight this fpecies has a confiderable refemb lance to the Ervum hirfutum, but the flighteft attention will 

 difcover the difference ; in the Ervum hirfutum the pods contain only two feeds and are hairy ; in the Tetrafpermum 

 they contain four and are fmooth ; in the hirfutum the flowers grow in a kind of clufer, in this fpecies there is feldom 

 more than two grow together. 



The figure which 1 have given is intended to reprefent the plant as it grows among the Com; when it is 

 found by itfelf and in a poor foil it is often not lo large.
