The .specimens collected are distinguish- 

 ed by having the jjistillate spikes, especially 

 the lower ones, very loosely flowered, 1'. 

 sparsa Kukentii. 1. c. (1912) p. 161. The 

 distance between the lower flowers in the 

 spike is to 1 cm. The terminal staminate 

 spike is 2 to 2,5 cm. long, on slender, fre- 

 quently slightly relaxed peduncles, 2 to 3 

 cm. long. The upper pistillate spikes now 

 and then androgAnous, with staminate flo- 

 wers at the summit. The glumes of tiic 

 pistillate spikes are very short, about 2 mm. 



long, broadly ovate, with a very long and produced, narrow midrib, to 9 or 10 nmi. 

 long, rough along the margin, f. longearislala Kom.viujw, <I>.i. JMaui.T.i.x |iiii I (1901) p. 

 378. The central i:)art of the glume and the drawn out midrib are green, for the 

 rest membranous. The perigv'nia on each side with a distinct lateral nerve, which is 

 continued upwards in the beak. The perigynia, including the beak, are from 6 to 7 mm. 

 long, and projecting far beyond the glume itself, which is only 2 mm. long, and 1,5 mm. 

 broad. The leaves along the margin and on the midrib rather rough. The nut is triquet- 

 rous, with concave sides, from 2 to 2.5 nun. long, with a long, generally fragile style. 

 The specimens taken in the first half of June are in flower, and partly past flowering. 



Scattered in thickets of foliferous trees along the Yenisei, and in moist thickets 

 on the islets, near list Abakansk. 



Distribution: Northern and eastern Asia.
