Lime-Grass, or Elymus, L. a genus of plants comprising twelve species, three of which are natives of Britain : the principal of these is the arenarius, or Upright Sea Lime-grass, which grows on the sea coast, and flowers in the months of July and August.—It is eaten by cows, horses, and goats, but refused by sheep;—Dr. Wi-thering questions whether it may not be advantageously formed into ropes, in the same manner as the Tough Feather-grass (Stipa tenacis-sima, L.), is manufactured in Spain.—This plant is of essential service on the coast, for preventing the encroachment of the sea, in which respect it saves millions of florins to the Dutch, who cultivate it with great industry.—Its mealy seeds and roots have, in times of scarcity, been converted into bread ; and the grass itself, while young, affords proper food for cattle.
