Cyperus imbricatus
Content
Description
Perennial with very short rhizome.
Leaves canaliculate, coriaceous, scabrous on the margins, pale green beneath, 5-10(-15) mm wide;
Inflorescence compound or subdecompound, up to 20 cm long and wide.
Stamens 3;
Distribution
Africa: Guinea (Guinea present), Asia-Tropical: Maluku (Maluku present); New Guinea present ‒ present, Pantropical present
Pantropical; widely distributed in Malesia, not yet known from the Moluccas. Only recently collected in New Guinea; “Guinea” in MIQUEL, l.c. 277, does not relate to New Guinea, as VALCKENIER SURINGAR and KÜKENTHAL supposed.
Uses
According to BROWN (1920) l.c., in some parts of the Philippines the outer portions of the stems are stripped, dried in the shade, and used for weaving mats, mattings, and screens.
Notes
A highly polymorphous species. The common Malesian form is figured in VALCKENIER SURINGAR's t. 4 f. 38b, whereas the plant of f. 38a (not distinguished nomenclaturally) is very rare in Malesia (e.g. BACKER 8131, 24423). The two forms are connected by many intermediates. The latter one is possibly identical with C. imbricatus var. densespicatus (HAYATA) . — C. densespicatus .
SURINGAR 'S f. 39 represents an anthelule of a specimen determined by CLARKE as C. exaltatus var. amoena CLARKE, but which belongs to C. imbricatus, as was already pointed out by SURINGAR.
