FRYE 



Lower leaves very small, scale-like; upper leaves ligulate, width to 

 length about as i : 5-6, 4-6 cm. long, strongly transversely undu- 

 late, much crisped and incurved when dry, spreading when moist, 

 lamina with transverse rows of teeth on back. Margin bordered 

 with 2 3 rows of very narrow brownish cells, sharply spinose for the 

 greater part of its length with strong and usually paired teeth. 

 Lamellae 2-6, straight, 3-5 cells high, occasionally as much as 7
