Stem smooth, glabrous, slender, hollow, decumbent, rooting, the extremities 

 ascending, branched. Leaves broadly lanceolate, equally attenuated at 

 both ends, acute, glabrous, with the exception of the midrib beneath, 

 which is covered with adpressed hairs, the margin ciliated with minute 

 hairs pointing forwards, both surfaces covered with minute prominent 

 points, sometimes veiy shortly stalked, but more commonly sessile. 

 Stipules moderate, with numerous adpressed hairs, fringed with the long 

 stiff setose points of the excurrent nerves. Flowers small, in slender 

 few-flowered lax spikes, commonly 2 together ; the bractese small, slen- 

 der, and fringed with long stiff setose points, about 2-flowered, the 

 lowest bractea very distant from the next ; flowers 5-fid, 8-androus, 

 semi-3-gynous ; pedicels jointed just below the flower. Fruit 3-quetrous, 

 its faces broadly ovate and acute, smooth but opake.
