Group Z («.?s)._VESICARI^. 



Rootstock subcajspitosc or more or less creeping, with short or 

 elongate stolons. Spikes rather remote, rarely approximate. Male 

 spikes 2 to 5, rarely only 1, the uppermost one stalked. Female 

 spikes 1 to 4, dense, on exserted stalks, the upper ones shortly stalked 

 or siibsessile. Glumes of the female flowers reddish-brown or choco- 

 late-brown, acute or subaristate. Bracts foliaceous, long, without 

 closed sheaths. Fruit bro-ivn or yellow or olive-yellow, usually ovoid, 

 scarcely trigonous, considerably or greatly inflated, often bladderlike, 

 more or less distinctly ribbed, glabrous or rarely pubescent, with a 

 long or short beak ending in 2 small teeth. Stigmas 3, rarely 2. Nut 

 trigonous or triquetrous, or lenticular when there are but 2 stigmas, 

 very loosely covered by the perigynium. 



Stem leafy in the lower half or only at the base. Leaves broad or 

 rather narrow.

Rootstock extensively creeping with long stolons. Stem erect, 

 leafy throughout, very stout, stiff, acutely triquetrous, rough in the 

 upper part. Leaves shorter than the stem, rather firm, very broadly 

 linear, flat, rough on the margins, bright green above, glaucous 

 beneath. Male spikes 2 to 3, erect, cylindrical, subobtuse, with long 

 oblong dark pin-plish-brown glumes, those in the middle of the spike 

 obtuse : anthers obtuse without any apiculus, or with an extremely 

 short one. Female spikes 2 to 4 (usually 3), rather remote, the 

 lowest ones shortly stalked, the rest subsessile or sessile, erect, rather 

 thickly cylindrical, obtuse, very dense, very many-flowered. Bracts 

 not sheathing, foliaceous, the lowest one with a long foliaceous lamina 

 exceeding the male spike. Glumes of the female flowers lanceolate, 

 acute, often tapering into short rough awns or long cusps, dark pur- 

 plish-brown, with narrow green midribs, usually a little shorter and 

 always narrower than the fruit. Fruit eprcading-ascending, ultimately 

 spreading, substipitate, ovate-lanceolate, acuminate, conico-ovoid- 

 trigonous, considerably inflated, rather strongly ribbed, glabrous, 

 rather dim, greyish-brown, rather gradually narrowed into a rather 

 short straight smooth or slightly_ deflexed 2-toothed beak, about
