Differing from some others of its genus tliis pretty little plant bears 

 bright, gay flowers which are all alike. They blow out early in the season 

 and soon quite in the orthodo.x way set about the forming and maturing of 

 their seeds. The leaves before they perish in the autumn turn to a charm- 

 ing bright red. 



H. corynibbsuvt, pine-barren frost weed, grows also in sandy barrens and 

 in places along the coast from Louisiana and Florida to North Carolina. 

 It is one which bears two kinds of flowers. Early in April those with 

 petals and very pretty unfold in cymes. Then later in the season the 

 plant blooms again, producing this time small, inconspicuous flowers in 

 almost sessile, cymose clusters. They have no petals, and while they 

 mature seeds as do the larger flowers, they are not more fertile, for their 

 capsules are neither so large nor so well filled. Their calyxes, the leaves, 

 and the plant's shrubby stems are all covered with a hoary pubescence.
