 clothed with a dense white tomentum. Leaves opposite, 

 oblongly linear, bluntish, or scarcely acute, the mar- 

 gins revolute, thickly clothed on both sides with a 

 hoary white tomentum, so that they are of a greyish 

 white on both sides, but whitest underneath. Petioles 

 short, also densely woolly. Stipules narrowly linear,
