A perennial dwarf herb, stoloniferous ; rhizome and stolons 

 long-repent underground, filiform, pale, loosely ramose ; nodes 

 distant, rooting, provided with opposite minute scales ; intcr- 

 nodes long ; roots fibrous, filiform. Stem (epigaeous) short, 

 erect, or ascending at the base, about 3—8 cm. long, simple or 

 sometimes laxly ramose above (branches axillary, attaining 

 ) > i '; 8 z m. long when well developed, spreading), densely pu- 

 bescent with retrorso-spreading pale hairs, foliiferous and flori- 

 ferous towards the top, but laxly with opposite scaly leaves 

 below, annual. Leaves opposite in 3— 1-pairs, those of the supe- 

 rior 2— 3-pairs approximate, falsely verticillate, shortly petiolate, 

 but sessile in the superior ones, patent, green, bullato-rugose, 

 obovate to narrowly obovate, or sometimes oval, cuneate below 

 and acute to subcordate at the base, rotundate with an obtuse 

 or acutish tip at the apex, coarsely crenato-dentate with del- 

 toid or depressed-ovate obtuse- rounded- or acutish-tipped teeth 

 except the lower cuneate portion which is entire, 2-9 cm. long, 

 1^-7 cm. broad, pubescent above, pubescent on the midrib 

 veins and veinlets or whole surface beneath ; midrib prominent 

 beneath ; veins about 3-6 on each side, erect-patent, prominent 

 beneath, pinnately arranged ; veinlets loosely reticulated ; lower 

 ones much reduced, usually squamiform, the upper pair often 

 larger, narrowly cuneato-spathulate or cuneato-flabellate. Ver-
