This plant is found on the broken sandy banks bordering small water- 

 courses, and is abundant in such situations in the uplands of Louisiana. 

 It seldom grows beyond the size of a bush. The blossoms are lasting, and 

 although without odour, are pleasing to the eye, on account of their 

 pure white colour when first expanded ; they dry on the stalks, retaining 

 their form, and remaining until winter. The species is characterized by 

 its oblong, deeply sinuate leaves, which are downy beneath, and its ra- 

 diated loosely thyrsiform cymes.
