Inflorescence simple, spiciform, sometimes slightly branched at the base, cylindrical-conical, acute, 2-8 cm by 1-2½ cm at the base;

Notes

Readily recognizable by its spike-like inflorescence with non-sheathing bracts. Carex nikoensis Franch. & Savat., with slightly larger spikelets in denser spikes and somewhat longer beak of the utricle than in typical C. satzu- mensis, was already reduced to C. satzumensis by Franchet (1896).
The specific epithet is frequently spelt4satsumen- sis\ but the spelling 'satzumensisemployed when the species was validly published, must be retained.
In an abnormal inflorescence of Santos 5776 from Luzon I found in all branches between the fertile cladoprophyll and the normal utricles some deeply split utricles containing one or some flowers besides the $ one, a situation normal in Schoenoxiphium and Kobresia.
