(moiioecious) : and in a few others, separate spikes on sepa- 

 rate plants {(Ucecioiis). The $ flowers consist of 3 stamens, 

 with anthers attached to the filament by the base, i. e,, innate. 



The ? is an ovary invested with 

 a sack {perigynium) composed of 

 2 united glumes. The 2 or three 

 stigmas project from the beak or 

 orifice of the perigynium which 

 finally incloses the achenium. 



2. Specific Characters. — 

 Among the multitudinous forms 

 of Oarex, we select the two shown 

 in the cuts, common in our wet 

 meadows. The Jewelled Carex 

 (Fig. LXXI, 1), may be distin- 

 guished thus : A 

 smooth, light- 

 green Carex, 2 

 feet high, with 

 narrow leaves and 

 bracts, monce- 

 cious, with the 

 sterile ( 6 ) spikes 

 2 or 3, and the fer- 

 tile (?) 1 or 2, 

 oval or oblong, on 

 very short pedun- 

 cles ; the perigy- 

 nia turgid-ovoid, 

 reclining, taper- 

 ing into a long, 

 straight, rough beak, much longer than the lanceolate 

 glume ; stigmas 3, achenium 3-cornered. 



5, Carex flava ; 6, a glume ; 7, a flower (periirynlum) 

 \vith 3 stigmas Issuing from the orifice ; 8, ? flower of Carex 

 riyuEris ; g, the glume, p, the bottle-shaped perigynium 

 2-toothed at top, envelojuuf^ the ovary ; stigmas 3 ; 9, a 

 perfect flower of Scirpus lacustris, with 6 setas, 3 stamens, 

 8 stigmas.
