 shaped scar with a deep depression in the centre. Commonly 

 found in timothy and other grass seeds.

 sown or planted, is in that Place a Weed. The whole Benefit of the Tillage was intended

Thomas Hale, The Compleat Qody of Husbandry, 1756. 



The whole land 

 Is full of weeds; her fairest flowers choked up. 

 Her fruit trees all unprun'd, her hedges ruin'd. 

 Her knots disorder'd, and her wholesome herbs 

 Swarming with caterpillars. 



Shakespeare, Richard II, Act III, So. iv, 1593.

 like belles, blewe and hollo we, the seed is black, and almost three square, lying in knopp>es 

 and huskes, after the same manner as the seede of the white Blnde weede. 



Lyte, 1578.
