Tricuspis seslerioides, Torr. — See Triodia cuprcea, which is the same. 



Triodia cuprsea, Jacq. — False Red-top, Tall Red-top, Fall Red-top, 

 Purple-top. 



A tall, native perennial frequent in dry, sandy fields. It is a 



showy grass three to five feet high, blooming from August to 



October. Appare-ntly of no agricultural value. 



Triple- awned-grass. — Generic name for species of Aristida. 



Tripsacum dactyloides, Linn. — Gama-grass, Sesame- 

 grass, Bull-grass. 

 This grass is occasionally seen in rich soils along 

 rivers and creeks. It grows in large tufts, producing a 

 great mass of broad leaves, which, when young and 

 succulent, are eaten with avidity by stock. The roots 

 are strong and somewhat creeping; the stems are solid 

 and grow from three to seven feet high. The flowers 

 are in slender spikes, these standing singly, or more 

 often, two to three together. When abundant, gama 

 affords a large amount of natural forage, and is 

 valuable to this extent.
