 obsoletely white-cottony above ; branches striate, lax ; leaves 

 narrowly ellipsoidal or lanceolate-oblong, narrowed towards both 

 ends, acviminate or apiculate at the apex, often attenuate to the 

 sessile and somewhat auriculute base, herbaceous, toothed, more 

 or less cottony, especially beneath, with white often deciduous
