Hab. Plentiful on Menzies' Island, and on sandy banks of the Columbia upwards. Douglas, — Only one 

 specimen of this, I regret to say, is in my possession, and it has no more than a few male flowers developed 

 amongst the small terminal leaves, which seem to form a kind of involucre beneath them. Whole plant 

 scarcely the height of one's finger ; clothed every where with stellated tomentum ; the petioles and stem and 

 branches, besides, bearing patent bristles or rigid hairs, somewhat bulbous at their base. Leaves in general 

 nearly an inch long, most crowded at the top of the branches, where the innermost or uppermost are very 

 small about the flowers.
