 Plates MDCLXXXIII. MDCLXXXTV. 



Rootstock creeping, with slioi't somewhat chordorrhizal branches 

 and short stolons. Stem ascending or erect, leafy in the lower half, 

 rather slender, not wiry, triangular, slightly rough in the upper half. 

 Leaves nearly as long as the stem, narrowly linear, flat, keeled, rough 

 on the margins towards the apex, faintly ribbed above, bright green both 

 above and beneath. Male spike 1, more rarely 2, the upper or only 

 one rather longly stalked, linear-fusiform, very acute, with oblong- 

 lanceolate subobtuse dark chocolate-brown glumes with narrow silvery 

 scarious margins. Female spikes 1 to 3, rather remote or subap- 

 proximate, the lowest one shortly stalked, the uppermost sessile, at 

 first erect, afterwai-ds inclined, oval-ovoid or oblong-ovoid, obtuse, 

 dense, many-flowered. Bracts not sheathing, foliaceous, the lowest 

 one with a rather long foliaceous lamina nearly equalling the male 

 spike. Glumes of the female flowers oval or oval-lanceolate, sub- 

 obtuse or subacute, dark purplish-brown or purplish-black, with 

 narrow pale or concolorous midribs and margins, much shorter and 

 narrower than the fruit. Fruit ultimately ascending, stipitate, oval 

 or ovate, rather abruptly acuminate, ovoid, scarcely trigonous, greatly 

 inflated and bladderhke, rather faiiitly ribbed, or with no ribs but the 

 marginal ones, which are stronger than the others when the latter are 

 present, glabrous, shining, olive, tinged with purplish-brown or wholly 

 purplish-brown, sometimes nearly black, more or less abruptly nar- 

 rowed into a short straight smooth 2-toothed beak, not more than 

 one-fifth the length of the fruit, and often considerably shorter. 

 Stigmas 2. Nut pale yellowish-brown, roundish-obovate, lenticular, 

 but more convex on the back than on the face, very loosely covered 

 by the perigynium.
