ish, chartaceous, slightly concave above, convex beneath, narrowly sulcate 
dorsally in a median line up to the acute apex, narrowly deltoid from a short 
broadly obdeltoid base, 6 to 10-ciliate on the margins, occasionally minutely 
4 to 8-ciliate along the edges of the dorsal suture; longest leaves 1.25 mm. long, 
0.4 mm. wide at the base; cilia 0.03 to 0.06 mm. long; sete white with a reddish 
base, scabrous, up to 1 mm. long. 
Spikes nearly quadrangular, up to 15 mm. long, 1 mm. thick; sporophylls 1.5 
mm. long, 0.8 mm. wide at the base, narrowly sulcate dorsally in a median line 
up to the acute apex, auriculate, minutely 10 to 20-ciliate on the margin, occa- 
sionally 4 to 8-ciliate on the edges of the dorsal suture near the base; auricles 
broadly obdeltoid, ciliate; cilia more minute and set# slightly shorter than on 
the stem leaves. 
Megasporangia yellowish, 0.6 mm. in widest diameter; megaspores rugose on 
the commissural side, nearly smooth on the opposite side, 0.8 mm. in diameter ; 
microsporangia 0.6 mm. in widest diameter, reniform, orange or brownish; 
microspores abundant, bright orange, 0.03 mm, in diameter.

Type in the U. S. National Herbarium, no. 723895, collected on hillocks of 
loose sand in shade of scrubby oaks near Carrabelle, Florida, March 15, 1898, 
by Charles Mohr. 
The following specimens have been examined: 
Fiogwa: Carrabelle, Mohr, March 10, 1898 (N), and March 14, 1898 (N); 
“Chapman” (Biltmore distribution, no. 3482b) (N, G, Y); “Chapman” 
(without number) (M). Indian River, Palmer (M, G). Palatka, 
Hasbrouck (N). Fort Lauderdale, Small é Carter 1013 (G, Y); Small, 
Carter & Small 8349 (Y); Small € Wilson 1762 (Y). Clearwater, 
Huger (Y). 
DISTRIBUTION: Sand dunes and barrens, throughout Florida. 
This species is closely allied to S. humifusa, but differs in the points noted 
under that species. Its next closest ally, S. arenicola, differs in the long- 
adnate base of the leaf, smoother megaspores, fewer ranks of leaves, and cor- 
respondingly smaller stems. The extremely closely appressed leaves give the 
stem an appearance not unlike that of stiff cord.
