 Grown on poor, light land.

THE BOTANICAL DEPARTMENT. » 



Thirty-one specimens of grasses and other forage plants at full length, 

 dried under pressure and mounted on heavy paper two feet wide and from 

 two to eleven feet long, as follows: 



Agropyrum caninuvi, R. and S. Tall Wheat Grass. A rather slender grass with 

 weak stems. Of some promise to use in mixtures for meadows. Native of Rocky 

 Mountains. 



Agropyruvi caninum, R. and S. Tall Wheat Grass. This wild grass found in Mich- 

 igan on dry soil, seems to promise well to employ in mixtures for meadows. 



Agropyrum repens, L. Quick or Couch Grass. Of fair value for meadow or pasture. 

 It seldom seeds, but spreads rapidly by its numerous root stocks. One of our very 

 worst weeds. To kill: Plow shallow in fall or early spring and cultivate every three 

 days, or often enough to prevent the appearance of green leaves. Native of Europe. 



Agropyru7n teneruvi, Vasey. Slender Wheat Grass. Apparently promising for 

 meadows to mix with clovers or other grasses. A new thing worth trying. Native of 

 North America west of Mississippi. 



Agropyrum unilaterale, V. and S. One-sided Wheat Grass. Of some promise to 

 mix with clovers or other grasses for meadows. Native of North America west of 

 the Mississippi. 



Agrostis alba, L, Red Top. Herd's Grass. A perennial with root stocks, flowering 

 rather late. One of the best known and most valuable grasses for river bottoms either 

 for grazing or for mowing. Native of Europe. 



Alopecurus pratensis, L. Meadow Foxtail. Early, nutritious, suitable for meadow 

 or pasture in damp climates. Much grown iu Great Britain; of much less value in 

 most parts of the United States. Native of Europe. 



Arrhenatherum avenaceum, Beauv. Tall Oat-grass. A tall, rapidly growing, early 

 perennial; in many places highly prized for pasture or meadow. It is well to mix with 

 red clover and orchard grass. Native of Europe. 



Cynodon dactylon, Pers. Bermuda Grass. Thriving in hot climates and spreading 

 rapidly by stout root stocks. Of good quality for hay or pasture; suitable for a lawn 

 in warm climates. Apparently of little value in the northern states. Found in warm 

 countries. 



Dactylis glomerata, L. Orchard Grass. Cock's Foot. Valuable for pasture or for 

 mowing in good soil. It must be cut or fed early to prevent seeding. Much grown in 

 Great Britain and on the continent of Europe. Native of Europe. 



Eleusine coracana, Gaertn. This annual grass is a native of India, where it is grown 

 on light soils. The yield of seeds is large, much resembling those of millet. 



Elymus virgiyiicus, L Wild Rye, Lyme-grass. A stout perennial, not thought to 

 be of great value. Shown here for comparison with a larger variety. Native of U. S. 



Elumus virginicus L. var. glaucus. Glaucous Lyme-grass. Raised from seeds of 

 one selected plant. This variety is larger than the species which grew near it. Native 

 of Michigan. 



Festuca elatior, Jj. \av. arundinacea, K. Taller Meadow Fescue. A large peren- 

 nial of promise for pasture or hay, when grown bv itself, or better when mixed with
