This subspecies is especially characterized by its short and Ihick spikes, of a |)allid 

 yellowish brown colour. The culms arc erect, from iiO to 10 cm. hiyh. The leaves 

 are flat, comparati\ely broad and short, 

 to 6 mm. broad, of a greyish green 

 colour, rough at the margin and along 

 the nerves underneath, from % to H 

 of the length of the culms. The number 

 of the spikes to 7, nearly ovoid, on 

 capillaceous, relaxed .stalks, from I to 

 2 cm. long. The upper spike is com- 

 monly wholly staminate, or, at limes, 

 with some few pistillate flowers at the 

 summit. The pistillate spikes are com- 

 paratively short and obtuse, broadly 

 obovate, to 1,5 cm. long. The glumes 

 are ovate-lanceolate, subacute, 3 mm. 

 long, 1 mm. broad, mostly broadest 

 above the middle, not distinctly sca- 

 rious-margined, of a shining yellowish 

 brown colour, with a greenish midrib, 

 reaching the summit of the glume. The 

 perigynia are rather broadly oval, 

 inflated, from 3,5 to 1 nun. long, and 



2,5 mm. broad, longer and broader than the glume, nerveless, slightly trigonous b<'Io\v. 

 compressed above, of a yellowish brown colour, with greenish margins, nearly hyaline, 

 .slightly rough along the margin in the upper part, furnished above with a short scarious-
