 in each extra-axillary fascicle, the peduncles varying from 6 to 

 20 lines in length ; the corolla, the size of that of Capsicum fru- 

 tescens, has an expanded 5-partite border, the mouth of the short 

 tube being pilose, the filaments are hairy on the margins. The 

 berries are red, globular, 3 lines in diameter, and are supported 

 by their small persistent calyx on slender deflexed peduncles.
