TRIANDRIA— MONOGYNIA. Scirpus. 61 



About the banks of large rivers. 



In the Thames at Battersea and Limehouse. Doody. Above 

 Westminsterbridge. Mr. E. Forster. On the banks of the Arun, 

 near Arundel castle. Mr. Borrer. 



Perennial. August. 



Root creeping. Leaf none. Stem rather convex between the 

 angles ; not flat, or concave, as in S'. triqueter. Panicle most 

 like S. lacustris, but the principal bractea is often longer, and 

 more of the texture of the stem ; still evincing its true nature, 

 as I apprehend, by being channelled ; though with regard to 

 terminal or lateral inflorescence, the present species is inter- 

 mediate in nature, between lacustris and triqueter. Spikes ovate, 

 numerous, rusty. Stigm. 2. Seed smooth, with 6 rough bristles 

 beneath. 



**** Stem triangular. Panicle leafy. 



12. S. maritimus . Salt-marsh Club- rush. 



Stem triangular. Panicle terminal, leafy. Spikes conglo- 

 merate. Glumes torn, with an intermediate point. Stigmas 

 three.

jRoo< creeping; in /3 knotty. Stem 1 — 3 feet high, striated ; roughish 

 at the angles ; leafy at the base and summit. Leaves sheathing, 

 keeled, dark-green, rough-edged, taper-pointed. Spikes ovate, 

 soft, partly stalked, solitary or aggregate ; occasionally elongated 

 and cylindrical. Glumes membranous, of a dark uniform brown, 

 often minutely downy ; the point, or awn, longer than in the 

 neighbouring species. Seed roundish, shining brown, with 3 

 blunt angles, and from 1 to 5 or 6 rough bristles.
