Fimbristylis cymosa


Glabrous perennial with short rhizome. Leaves much shorter than the stems, coriaceous, flat or canaliculate, abruptly acuminate, scabrid on the margins, 1-2(-3) mm wide; Inflorescence compound or decompound, loose to very dense, not rarely subcapitate, with many to numerous spikelets. Stamens 1-3;


Asia-Tropical, Pantropic present
Pantropic; throughout Malesia.


In open sandy, clayish, or rocky places by the sea: sandy beaches, wet dune hollows, muddy places in the mangrove, etc.; locally often abundant; sometimes inland near hot springs. See .


In the wide sense accepted here extremely variable. The spikelets may be all solitary or clustered on the well developed rays, or the inflorescence may be contracted into a single head. Glumes, anthers, and style vary considerably in size. The nut may be biconvex or trigonous, smooth or verruculose. The Malesian plants are distigmatic as a rule (F. spatha- cea), but often there are a few tristigmatic flowers among the distigmatic ones. Plants with all or nearly all the flowers tristigmatic (F. cymosa s. str.) are very rare in Malesia (e.g. RAMOS 33444 from Luzon); they prevail in other regions.
F. capitulifera MERR. from the Batan and Babuyan Islands is a remarkable form with the spikelets in dense clusters on well-developed rays, the oblong glumes with shortly excurrent midnerve, a slender style and somewhat smaller nut. It is usually tristigmatic, but distigmatic flowers occur. The spikelets are not always so strikingly clustered. It comes near F. cymosa var. umbellato-capitata (F. spathacea var. umbellato-capitata ,, 8 (); F. cymosa subsp. umbellato-capitata ).
F. pycnocephala HILLEBR., l c., is according to , specifically distinct from F. cymosa, whereas KOYAMA, 1961, refers it to the synonymy of F. spathacea var. umbellato-capitata.
