EuLust perennial, attaining about 1| m. in height. Roots thick, 

 yellow. Stem stout, erect, simple, flexuous, striato-sulcate, fistulous, glabrous, 

 but often pubescent under the nodes, often tinged with rose-purple colour. 

 Leaves alternate, ample, petioled, gradually diminishing in size and trans- 

 ferring into bracts, oblong-ovate, but ovate-lanceolate in the above ones, 

 broadly ovate to ovato-oblong in the radical ones, obtuse or acutish, broadly 

 cordate to rounded at the base, irregularly more or less waved and crispate, 

 herbaceous, glabrous above, scabrous-pubescent along veins and veinlets be- 

 neath, the largest one attaining about 47 cm. long, 28 cm. broad ; the midrib 

 stout, prominent beneath ; veins numerous, patulous ; veinlets reticulated ; 

 petiole shorter than the blade in the cauline leaves, but in the radical leaves 

 very slender and often longer than the blade ; ochrea membranaceous, longi- 

 tudinally nervate, 1-7 cm. long. Panicle loose, formed by the terminal and 

 axillary slender racemes ; rachis slender, erect, m(tre or less flexuous, striate, 

 sometimes abbreviated, often puberuleut, pubescent below the nodes; verticels 

 densely flowered, about 1-2^ cm. across, usually interruptedly remote one 

 another, but often approximate in the superior ones, the lower verticels 

 l)racteate ; bract leaf-like, linear to lanceolate, shortly petiolate, obtuse, or 

 acutish, acute at the base, more or less crispate on the margin, 2^-8 cm. long.
