Type in the U. S. National Herbarium, No. 723,895, collected on "hil- 

 locks of loose sand in shade of scrubby oaks" near Carrabelle, Florida, 

 March 15, 1898, by Charles Mohr. 



Closely agreeing with the type are the following specimens, all from 

 Florida: 



" Chapman " (Biltmore distribution No. 3432b). Dry sandy ridges in 

 the pine barrens, Carrabelle; A. M. Huger, Clearwater, January-February, 

 1902; Small, Carter, and Small, No. 3349, Fort Laudervale to Miami, 

 February, 1911; Small and Carter, No. 1013, Fort Lauderdale, Novemher 

 19 and 25, 1903; Small and Wilson, No. 1762, Fort Lauderdale, May 20, 

 1904. 



This species is somewhat closely allied to the rather common S. areni- 

 cola of the southeastern states, but differs in having the megaspores 

 somewhat rugose on the commissural side, a great number of ranks of 

 leaves, and a shorter leaf base. If differs from other forms in the group 

 in that the cilia of the dorsal suture are either very minute, or, more 

 commonly, entirely lacking. Moreover, the stiff cordlike appearance of 

 S. funiformis furnishes a striking character that easily distinguishes it 

 from any of its allies.
