A prostrate or diffuse shrub with terete branches, glabrous in 

 all its parts. Leaves not dense, opposite, spreading, very shortly 

 petiolate, narrow-ovate, 4 to 6 mm. long and about half as broad, 

 rounded and broad at the base, more narrowed towards the top 

 but not acute, flat or the margins slightly recurved, prominently 

 denticulate-ciliate, rather paler underneath. Flowers white with 

 the faintest tint of pink, terminal or the branchlets in the axils 

 of the bracts forming umbels of 2 to 8 flowers, occasionally with 

 branched rays, more rarely solitary and terminal or in the axils 

 of the uppermost leaves. Pedicels mostly longer than, or as long 

 as flowers, articulate above the middle, with two opposite small 

 broad bracts at the articulation. Calyx-tube turbinate, about 

 IJ mm. long, with short triangular lobes, faintly ciliate. Petals 

 orbicular, about twice as long as the calyx-lobes. Stamens 20 to 

 25 in a regular row round the margin of the disk; filaments all
