Annual, attaining 4-14 decim. in height. Stem erect, ligneous and 

 usually branched at the base (the branches ascending-erect), nodose, terete, 

 antrorsely depressed pilose but glabrous above, attaining about 4 mm. 

 across at the very base, the internodes usually shorter than the leaves. 

 Leaves very shortly j)etioled, lato -lanceolate to angustato-lanceolate, acu- 

 minate at the apex, rounded or obtuse or acute at the base, 2-lOcm. 

 long, 4— 29 mm. wide, membranaceous, more or less firm, antrorsely pilose 

 on both surfaces, antrorsely sculeato-ciliated on the margin ; lateral veins 

 many, erect-patent, arcuate upwards ; petiole pilose ; sheath longer than 

 the petiole, about 5-13 mm. long, truncate, antrorsely adi)ressed pilose, long- 

 ciliated with erect hairs. Inflorescence loosely ramose with filiform branches, 

 the internodes of the rachis and branches glabrous and glutinous towards 

 the top. Spikes slender, angustate, l^-7^cm, long, about 4mm. across, 

 rather densely flowered, but often interru])tedly flowered below ; bracts oval, 

 thinly pilose, long-ciliated, green but scarious on the margin. Flowers 

 3-7-fasciculate, shortly pedicellate, 2mm, long; pedicel very slightly longer 

 than the bracts. Perianth 4-5-fid, pale ; segments oval or oval-elliptical, 

 rounded-obtuse, concave. Stamens 7-8, included; filament subulato-filiform. 

 Ovary ellipsoid ; styles 3, connate below, shorter than the ovary. Akene
