An erect annual, attaining about 1J m. in height ; tap-root 

 hard when dried, perpendicular, ramose. Stem terete, ramose 

 above or below, hard when dried, thinly covered with simple 

 bifurcate and stellate pubescent hairs but afterwards more or less 

 glabrate, and with a line (rarely 2 lines) of densely pubescent 

 curved stellate hairs along one side shifting at each node, 

 attaining about 1| cm. across, usually straight or somewhat 

 flexuous ; bark fibred, thick, light green, rather textile, anasto- 

 moticly marked with light green borders and pale fusiform 

 aleolae ; branches loose, erect-patent, spare, leafy throughout, 

 apical ones larger. Leaves simple, usually not lobed but 

 slightly 3— lobed above in well developed ones, petiolate, sparse, 

 oval, ovate, or elliptical, and often subrhombic, oblong-lanceo- 

 late in the superior ones, long-acuminate, rounded or sub- 

 cordate at the base, unequally serrato- or crenato-dentate with 

 depressed-deltoid or depressed-ovato-deltoid acute or subobtuse 

 teeth, membranaceous, spersely pubescent with erect-patent or 

 spreading simple hairs (hairs denser on the midrib and veins and 

 thinly mixed with stellate ones) on both surfaces and ciliated 

 with fine simple hairs, about 2^—17 cm. long, 1—11 cm. wide, sub-

 straight simple hairs, but on front side with a densely pubescent 

 line with short curved stellate hairs, |-11^ cm. long; stipules 

 minute, then reflexed, subulate, subulato-deltoid, or ovato-lanceo- 

 late, setaceo-acuminate, spreadingly piloso-ciliated on margin 

 and pilose on the midrib dorsally, about 3-8 mm. long, persistent. 

 Cymes extra-axillary, short, shortly ramose, densely few to
