 Europe, Central Asia to Japan, S. Africa. 



Glabrous, except margin of glumes. Rhizome elongate, branching ; scales ovate- 

 triangular, striate, rusty-brown, often rubbed off. Stems 1-3 ft., two faces plane, 

 third (flower-bearing) concave. Leaves ^3 in. long, or hardly any. Lowest hract 

 ^—2 in., triquetrous, as though continuing stem. Kays of umbel ^2 in. with 2-8 

 clustered spikelets on each ; or umbel congested nearly to a single head. Spikelets 

 i in. long, broad cylindric, rusty-brown (in the Himal. form). Glumes broadly 

 ovate, keeled, notched at top with a short mucro in notch ; margins scarious, ciliate, 

 hairy. Bristles rigid, brown-red, often about as long as nut, incurved over its 

 shoulders, scabrous with short white reflexed teeth (not plumose). Stamens 3, 

 anthers with short red crests. Style fide Boeckeler sometimes 3-fid. iVwi less 

 than \ length of glume. — As to the specific name, Bentham has shown 1. e. that this 

 plant was S. triqueter, Linn., and that Boeckeler erred in discarding that name. 

 It hardly differs from S. lacustris var. carinata, except by the more acutely tri- 

 quetrous stem, 



Var. segregata ; ultimate rays of the umbel all (or nearly all) with one spikelet, 

 bristles 3 (sometimes 2). ? S. subulatus, Prain in Journ. As. 8oc. Seng. Ix., part 2,

 — Stolons slender. Bays of the inflorescence sometimes again divided, sometimes 

 SJ in. long. Bristles 3 or 2 (usually 4 or more in S. triqueter, typ.), black-red. 



14. S- lacustris, Linn. 8p. PI. 72 ; stems stout terete or somewhat 

 trigonous, umbels usually compound, spikelets clustered and solitary, 

 bristles 6-5 retrorsely simply scabrous, style 2-3-fid, nut obovoid smooth

Rhizome horizontal. Stems IJ-i ft., often standing in water. Leaves hardly 

 any, or sometimes 4 in., or (floating) 1-2 ft. Umbel usually once or twice divided, 

 4-6 in. in diam., sometimes reduced almost to a small head; lowest bract suberect, 

 short. Spikelets J in. long. Olumes ovate, notched at top with a small mucro in 

 notch ; margins membranous, pilose. Bristles as long as the nut or reduced, some- 

 times almost 0. Stamens 3, anthers crested. Nut ^— J glume, plane-convex. — In 

 type 5. lacustris, the stem is terete, the style 3-fid ; var. Tdbemeemontawi differs 

 in style bifid ; var. carinata in stem obscurely trigonous. — (S. lacustris of S. America 

 is S. riparius, Presl.) . 



15. S. maritlmus, Linn. Sp. PL 74 ; stems robust trigonous, leaves 

 several long, umbel compound simple or capitate, glumes notched hairy 

 at top mucronate, bristles 6-3 retrorse-scabrous rarely subobsolete, style 

 3-fid (see var.), nut obovoid smooth finally black. Mees in Wight Contrib.
