Stem shrubby, nearly erect, or ascending, branched : 

 branches long* and slender, erect or ascending, smooth 

 and glossy, or slightly hairy, of a purple colour, more 

 or less warted. Leaves petiolate, linear, bluntish, bris-

 deeply channelled on the upper side, of a whitish green, 

 occasioned by a dense minute pubescence, underneath 

 clothed with a dense white tomentum. Petioles short,
