Hab. Sources of the Arkansa. 



Desc. Whole plant densely covered with a grayish stellate pubescence. 

 Stem branched ; upper branches compressed. Leaves lanceolate, 2-3 

 inches long, rugose ; margin erosely-serrate ; petioles 4-6 lines long. 

 Flowers growing in axillary clusters, from 3 to 5 on each common pedun- 

 cle, scarlet. Calyx campanulate, deeply 5-cleft, naked ; segments trian- 

 gular-lanceolate, acute. Corolla nearly twice as long as the calyx. Peri- 

 carps 12-14, not inflated, 1-2 seeded, bimucronate at the summit, distinctly 

 reticulate on the sides towards the base. Seeds triangular-reniform, smooth) 

 reddish. 



Obs. This appears to be a very distinct species. Its flowers 

 are about as large as those of S. rhombifolia.

 fruit ; but as De Candolle remarks, it is destitute of the exte- 

 rior calyx.
