224 FLOWERING PLANTS OF THE RIVIERA 



crowded in an umbellate cyme. Glumes lanceolate, midrib green, scabrid. 

 Nut triquetrous, pale. 



Damp places, sides of streams, etc., fairly common on the littoral. June- 

 August. 



C. Badius Desf. Perhaps only a var. of the last, with larger spikelets and 

 denser clusters. It grows in similar places and is equally common. June-August. 



C. globosus All. Root fibrous. Stem triquetrous. Leaves narrow, 

 shorter than the stem. Spikelets linear-lanceolate, in 1-3 globose heads, one 

 being sessile or nearly so, brownish or pinkish-yellow in colour. Glumes oblong 

 obtuse. Stamens 2. Stigmas 2. Nut obovate, much compressed, dotted and 

 rough. 



Marshy places, rare. At the mouth of the River Var near Nice, and at 

 Ventimiglia and Menton. June-November. 



C. f lavescens L. Root fibrous, annual. Stem somewhat triquetrous, with 

 narrow linear leaves shorter than the stem. Spikelets numerous, linear-lanceo- 

 late, yellowish, in bundles partly sessile and partly stalked. Glumes ovate, 

 i-nerved. Stamens and stigmas 2 each. Nuts very minute, much compressed, 

 dotted and rough. 



Marshes and damp, sandy places, uncommon. July-September. 



C. schoenoides Griseb. Root-stock creeping. Stem cylindrical, erect 

 and stiff. Leaves linear, channelled, glaucous, reflexed. Spikelets ovate- 

 lanceolate, glumes green with purple at the base ; spikelets brown, arranged in 

 a compact almost globose head. Stamens and stigmas 3. Nut ovate-elliptical, 

 trigonous. 



Sea-sands, common along the shore. May-July. 



C. serotinus Rottb. is a species not unlike C. longus, but more glaucous 

 and with thick, compressed triquetrous stem. Scales loosely imbricate, obtuse, 

 many-nerved, pale at border. Stamens 3, stigmas 2. Nut obovate-compressed. 

 Spikelets reddish-brown, lanceolate, very spreading. 



Marshy places and borders of streams. August-October. By the River Var 

 near Nice, near Frejus, St. Raphael, etc. Uncommon. 



SCIRPUS L. 



S. maritimus L. Root-stock creeping. Stems triangular, 2-4 ft. high, 

 with long flat-pointed leaves often far exceeding the stem. Spikelets rich brown, 

 ovoid or lanceolate, sometimes 2 or 3 in a close sessile cluster, more often 8-10 

 in a compound cluster, the outer ones stalked. Bracts long, leafy, pointed. 

 Glumes notched, with a fine point. Style 3-cleft. 



Marshes near the sea and ditches, often in great quantity. April-July. 



S. lacustris L. Lake Scirpus. Root-stock creeping. Stems stout, erect, 

 3-8 ft. high, cylindrical at base, gradually tapering upwards and becoming tri- 

 angular. Spikelets ovoid or oblong, in a compound lateral umbel or cluster, 

 with 2 or 3 leaf-like bracts. Glumes numerous, broad, brown, fringed, notched 

 at top, with a little mucro in the notch. Style 2 or 3 cleft. Nut smooth. 



Ponds, borders of rivers, and marshes, uncommon. May-July. 



S. Tabernaemontani Gmcl. A sub-species of the last, but more ap- 

 proaching S. maritimus in habit and size. Style 2-cleft ; glumes with raised 

 dots, but these characters are very inconstant. 



Marshes near the sea, near Toulon, Hyeres, and Ampus. 



S. Holoschaenus L. Clustered Scirpus. A stiff rush-like plant, with 

 cylindrical stems, 2-3 ft. high, with i or 2 stiff leaves sheathing the base. Spike- 

 lets very small and numerous, closely packed in one or more globular heads 

 forming an umbel, the longest stiff outer bract forming a continuation of the 

 stem. Spikelets light brown in colour. Style usually 2-cleft. 



Damp places and road-sides, common throughout the district. May-July. 



S. pungetls Vahl. is a smaller plant. One or two of the sheaths bear 

 short, narrow, keeled leaves. Spikelets few (3-6), sessile in a close cluster. Outer 

 bracts stiff, triangular.
