To further show that clovers and their mixtures with grasses called “seeds” have their own peculiar weeds, we subjoin one other table of the species of weeds observed in three kinds of seed crops as under:— 1. Old clover and common rye grass (second year). 2. “Old seeds,”—clover, trefoil, common and Italian rye grasses (second year). 3. New seeds, clover and rye grass (first year). No. 1 examined on August 31; 2 and 3 on the 24th September, 1859. 4. TABLE OF WEED-PLANTS IN SEEDS. The dashes (—) in three columns intimate the occurrence of the plants signified in the fields 1, 2, and 3 respectively.
