SCHEUCHZERIACEAE

 rootstocks; leaves linear, grass-like, broadly sheathing at base, tubu- 

 lar at the apex; flowers borne on a loose receme; fruit an inflated follicle. 



1. Scheuchzeria palustris L. Fig. 3, Map 4 



Widely scattered in Sphagnum bogs in New England. This species 

 is often overlooked when not in flower or fruit. The best diagnostic 

 character for sterile plants is the terminal pore at the tip fo the leaf. 

 North American plants belong to variety americana Fern, and differ 

 from the Eurasian plants in having larger fruits with beaked follicles. 

 Range extends from Newfoundland west to Manitoba and Washing- 

 ton, south to New Jersey, Pennsylvania, northern Ohio, northern Illi- 

 nois, northern Iowa, Nebraska, New Mexico, and California.
