Content
Description
Leaves subbasal, rigid, flattish to conduplicate, longer than the stems, often recurved, scabrid on the margins and on the upper surface towards the long-attenuate apex, 2-5 mm wide.
Inflorescence simple, spiciform, sometimes slightly branched at the base, cylindrical-conical, acute, 2-8 cm by 1-2½ cm at the base;
Distribution
Asia-Tropical: Philippines (Philippines present), Benguet present, Japan present, Luzon present, Southern America: Argentina Northeast (Formosa present), Tonkin present
Japan, Formosa, Tonkin; in Malesia: Philippines (Luzon: Benguet).
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.
