A Handbook of Nebraska Grasses. Ss 
ing stolons, similar to those found in Bermuda erass, 
which root at the nodes, each joint thus forming a new 
tuft. Thus a close mat of fine leaves is formed which may 
cover considerable areas. It is unsurpassed for winter 
pasturage and is considered one of the best grasses for 
sheep pastures. Throuout the State, but most abundant 
in the western counties. 
CALAMAGROSTIs. 
Calamagrostis canadensis. Yellowtop. (Fig. 50.) 
A stout native prairie grass of the western half of the 
State. It often occupies rather large areas to the exclu-

of fine quality. It grows best in rather low moist meadows 
and has done well under cultivation.

and Thomas Counties.

more common in the western part of the State. 
CALAMOVILEA. 
Calamovilfa longifolia. Long-leaved Reed Grass. (Fig. 40.) 
A stout long-leaved grass forming an extensive system 
of rhizomes. It is unsurpassed as a sand-binder for the 
semiarid regions tho of little or no forage value. Common 
in the Sand Hill region.

A rather soft and weak aquatic grass of central and 
western Nebraska. 
CENCHRUS. 
Cenchrus tribuloides. Sand Bur. (Fig. 23. 
A common annual weed thruout the State. If cut before 
the “burs” are formed it makes good hay.
