Root creeping. Culms 3 8 feet high, rounded all the way up, slightly 

 tapering ; outer or lower sheaths brown, leafless, upper ones end- 

 ing in a linear subulate channelled leaf 3 4 inches long. The 

 Involucres of 2 leaflets, varying much in length in general one is 

 nearly as long as the cyme, and ends in a green rigid point, the 

 other much shorter and more membranous, brown. There are be- 

 sides what may be called partial involucres to the clusters of spikelets, 

 larger than the glumes and often with a rigid point. Glumes 

 brown, fringed, 4 often emarginate, the nerve running up between 

 the notch into a macro. Stigmas 2 3. Fruit obovato-triquetrous, 

 surrounded by 6 bristles. The culms are much used for mats, 

 chair-bottoms, c., and form an article of trade.

 or very slightly compressed, sheaths leafy, spikelets terminal 

 germinate, involucrum I- leaved. Lightf. p. 88. E. B. /.1693. 



HAB. Moist gravelly places, common. FL July, Aug. 0. 



Culms tufted, 2 5 inches high, slender. Leaves I or 2 with sheathing 

 bases. Involucre of 1 subulate leaflet, green, dilated at the base, 

 erect and so appearing a continuation of the culm, having lateral 

 fructification. Spikelets I 2. Glumes broadly ovate, acute, 

 smooth, brown, with green margins and nerve. Stom. 2. Stig

ft Culms triangular. 



8. Sc. maritimus, (Salt-marsk Club-rush), culm leafy, spike-

HAB. Salt marshes near the coast, not uncommon. FL July. If. . 

 Root creeping, often swelling into knots or tubers. Culm 2 3 feet

larger than the cluster of spikelets. Spikelets large, ovate, brown. 



Stigmas 3. Bristles 3 4 at the base of the smooth obovato-trian- 



gular seed.
