C. stricta x torta, Fernald, n. hybr. "Culm tall, 7.5 dm. high, and strict as 

 in C. stricta ; leaves linear, acute as in C. torta, much shorter and softer 

 and with less attenuate tips than in C. stricta; bracts elongated, over- 

 topping the culm ; spikes erect, 1.5 to 6 cm. long, the pistillate loosely 

 flowered ; scales ovate-lanceolate, acute, dull brown with green middle 

 and narrow pale margin : perigynia ovate- lanceolate, thin, dull green, 

 nerveless, the elongate, generally empty, tip exceeding the scale and 

 sometimes recurved. Mt. Mansfield, Vt., July 3, 1896, (G. G. Ken- 

 nedy). Very clearly combining the characters of the two parents. In 

 the foliage and in most of the perigynia like C. torta; but in its tall, 

 stiff habit, and acute scales like C. stricta." — M. L. Fernald in letter.
