This species, from the greater length of its corolla, might be 

 referred to Acnistus^ did not the habit of the plant show it to 

 be congeneric with the above-mentioned species described by 

 Prof. Kunth. The larger of the geminate leaves are from 8 to 

 10 inches long, 2| to 3|- inches broad, upon petioles 5 to 8 lines 

 long, caniculate and hispid ; the smaller leaves in each pair are 

 only \^ to 3 inches long, upon a much shorter petiole, and they 

 are elliptic or ovate-elliptic, and acute at both ends. The flowers 

 are fasciculated upon distinct peduncles, and are about the size of 

 those of Lycium harharum. The calyx is urceolate, obsoletely 

 5-toothed, thin and smooth; the corolla is of a greenish white 

 colour, smooth, the border divided into five equal divisions j the 

 filaments are pilose at base, the anthers oblong, bursting longi- 

 tudinally; the style is smooth and longer than the stamens.
