Very much resembles O. jttipes FR. et SAV. (KUKENTHAL Cyperacese- 

 Caricoidefe in ENGL. Pfl.-reich p. 640, fig. 109), but differs from it in the 

 more approximately flowered female spicules, and in the very much shortly 

 peduncled male spicules. A sheath which is very much like cladoprophyllum 

 is always present at the base of the pedicel of a lateral spikelet.
