Stem shrubby, erect or a little flexuose, much bran- 

 ched, in our specimen from 3 to 4 feet high : branches 

 spreading, elongated, more or less hairy, and clothed 

 with a dense leprous tomentum, which by age becomes 

 of a brownish grey, and is densely spotted with innu- 

 merable minute black specks. Leaves variable, when 

 young quite white and hairy on both sides, sessile, 

 obovate, or oblong, more or less undulate and twisted, 

 a little oblique, three-nerved at the base, very rough and 

 uneven, the margins very rough or denticulate ; lower 

 ones shortest and broadest, ovate or obovate, bluntly 

 rounded, attenuated into a sort of footstalk at the base, 

 clothed on both sides with a thin white tomentum : the 

 next are narrower and longer, and less blunt, of a 

 greener colour, less tomentose, not so narrow at the 

 base, more undulate and twisted ; upper ones, when 

 young, quite white on both sides, much more hairy, ses- 

 sile, and acute : those on thejftower-stems quite sessile 

 and clasping the stem, much broader, ovate, acute,
