Glabrous, whole plant usually more or less red; stolons 0. Stems 2-11 in. 

 Leaves usually f length of stem, - in. broad, weak ; sheaths broad, usually scarious, 

 inflated. Bracts 2, lower 1-1| in. Spikelets 3-20 in 1 head, f by in. Glumes 

 close-packed, much imbricated at base, 9-15-striate, keel very acute excurrent con- 

 spicuously. Stamens 3; anthers nearly muticous. Nut obovoid, triquetrous with 

 concave faces, reticulate black and white ; style as long as nut, branches linear. 

 C. rubicundus, Vahl, is a Puerto Rico plant ; and the description can hardly (ad- 

 mitting error in habitat) refer to 0. Teneriffce, as Vahl does not describe the 

 excurrent mucro of the glumes. Finally, even were our plant C. rubicundus, Vahl, 

 it must take the earlier name of Teneriffce. The name C. nitens, Rottler, is 

 earlier j but 0. nitens, Retz., cannot be set aside, because almost the only certain 

 thing regarding it, is that it was not a Pycreus, and therefore not the Cyperus nitens, 

 auctorum.
