Stem very leafy, paniculato- or racemoso-corymbosely branched 

 at the apex, generally woolly in the lower part, sparingly clothed 

 with stellate down and simple woolly hairs in the upper part; 

 peduncles rather densely clothed with stellate down, sometimes 

 intermixed with hairs which are often black-based but not gland- 

 tipped. Leaves very numerous, commonly crowded in the lower 

 part of the stem ; the lowest ones elliptical- or oval-oblanceolate ; 

 middle ones elliptical or oval and attenuated at each end; the 

 upper ones ovate or ovate-lanceolate or lanceolate, broad or even 

 sub-cordate, but not amplexicaul at the base; all (except the 

 lowest) acute, remotely denticulate - serrate or dentate -serrate 

 towards the middle, more or less hairy with soft hairs on both sides 

 and especially on the veins beneath, ciliated with rather long hairs 

 on the margins. Anthodes moderately large, numerous, in a 

 corymb or short panicle or raceme terminated by the corymb, with
