12. K. polyphylla, Willd, ex Kunth, Enum. ii. 134. Rhizome 

 horizontal or obliquely descending, short, thick. Stems 10-20 in. long, 

 triquetrous at the top. Leaves usually short, sometimes J-| the length 

 of the stem, J-i in. broad. Head of 3-1 (usually 1) spikes ; bracts 

 5-8, lowest usually exceeding 4 in. long, similar to the leaves. Spikes 

 ovoid, ^ in. or more in diam., dense, green usually tinged with orange or 

 brown. Spikelets ^-J in. long, lanceolate, each perfecting 1 nut. 

 Nut-bearing glume scabrous, wingless on the keel, which is subexcurrent 

 into a mucro. Nut less than ^ the length of the glume, obovoid, 

 finally chestnut-coloured. — Boeck. in Linnapa, xxxv. 409 ; C. B. Clarke

This species hardly differs from K. melanosperma but by the more numerous 

 bracts. As to K. elata, Stead. (Syn. PI. Glum. ii. 70, not of Boeck.), the example 

 of Boivin, 1676, named elata by Steudel's hand in his own herbarium, is MarLscus 

 dregeanus, Kunth.

 scarcely at all trigonous. Leaves short. Head of 1 spike, ovoid, 

 exceeding J in. in length ; bracts 6-10, up to 6 in. long, more than 

 \ in. broad. Otherwise as K. polyphylla. — Durand & Schinz, Etudes Fl.

This might be treated as a variety of K. polyphylla, Kunth, which it is closely 

 allied to in all respects. But K. polyphylla has the stem sharply triquetrous at the 

 top, without any approach to the terete stem of K. teres.
