unisexual. Male-spikelets inferior, several-flowered, pedicellate, 

 1-2 to a fascicle, about 1^-2 mm. long ; glumes several, 

 fasciculately arranged, erect, subulato-oblong, 1-nerved ; outer 

 empty glumes 2, acuminate, carinate and puberulent dorsally, 

 shorter than or equal to the inner fertile glumes ; fertile glumes 

 scarioso-membranaceous, glabrous, with an obtuse tip, but the 

 outermost one similar to the empty ones in character ; pedicel 

 narrowly ancipito-alate, about 1^-2 mm. long. Male-flower 

 monandrous. Stamen glabrous ; filament linear-filiform, about 

 as long as the glumes ; anther linear-oblong, with a minute 

 projection of the connective at the apex. Female-spikelets 



superior, 1—3 to a fascicle, very shortly pedicellate ; glumes 2 

 or 3, exceeding the nut in length, erect-patent in fruit, narrowly 

 ovate, acuminate, concave, subcarinate and puberulent dor- 

 sally, entire and ciliated, 1— nerved, membranaceous, 2^—4? 

 mm. long, the lower one a little shorter than the superior 

 ones ; pedicel 2— bracteolate at the base, often with a rudi- 

 mentary female flower (pressed against the ovary) in the axil 

 of the upper bracteoles ; bracteoles (empty glumes) oblong or 

 ovato-oblong, obtuse or subbifid at apex, scarioso-membrana- 

 ceous, obscurely few-nerved, about 2 mm. or more long. Style 

 exserted, about 3 mm. long, divided into 3 branches from below 

 the middle, ferruginous ; branches filiform, scabrous ; ovary 

 oblong, sitting on the thick gynophore, smooth, about \ mm. 

 long, obtuse at apex ; gynophore somewhat shorter than the 

 ovary, about 2 mm. long. Nut minute, globose, umbonato- 

 rostrate at the top, 1-| mm. across, osseous, at first white when 

 dry, dull pale and slightly shining when fully mature, excellently 

 tessellate, quite glabrous ; disc thick, enlarged at the top, very
