branches measuring a foot and upwards. Its petioles and pedi- 

 cels are erect, and therefore are all somewhat secund : I have not 

 seen any caulinc leaves, but the floral leaves are much smaller, 

 greatly narrower, and upon a shorter petiole than in the follow- 

 ing species ; the pedicels are 2 to 4 lines long, the calyx is 3 hnes 

 long, and 1 line diameter, swelling afterwards to a length of 7 

 lines and a diameter of 5 lines : the corolla is 15 or 16 lines long, 

 and 10 to 13 hnes broad across the border; it is pubescent out- 



wi 



when the peduncle increases to a length of 9 Hnes and becomes 

 suddenly reflexed. The berry is 4 lines in diameter, enclosed 

 within the enlarged vesiciform calyx.

This plant possesses a habit similar to that of the former spe- 

 cies. The branching stems of woody texture are fistulose, smooth 

 and terete. The leaves are from 2^ to 3 inches lonj;, 2 to 2,i 

 mches broad, on a channeled petiole 5 inches long, tha't is nearly 

 rectangular with the stem : they are almost smooth, or sparsely 

 covered with very short rigid hairs : the peduncles are slender 

 i to 1 inch long ; the calyx is 5 hnes long, 2 lines diameter ; the 

 coroUa is 1 ^ inch long, contracted for the length of 5 lines to a 

 diameter of 1 line, and thence gradually swelling into a funnel 

 shape, IS 1 inch across the mouth; three nearly parallel nervures 

 extend along the middle of the lobes to the base of the tube ; the 

 stamens arise m the contraction of the tube, and the anthers.
