 I found tbis plant growing abundantly in the above-named 



portion of the Cordillera ; unfortunately the only specimen 

 gathered during my last rapid journey over the Andes was lost, 

 but some of the leaves and flowers were preserved with the 

 berries, collected at the same time. The leaves are somewhat 

 fleshy, roundly oval, 3 lines long and 2 or 3 lines broad, sud- 

 denly narrowed into a short petiole 2 lines in length : the 

 peduncle is 2 lines long; the cup-shaped calyx is 1| line long, 

 with four short equal teeth j the tube of the corolla is 5|^ lines 

 long, the lobes of the border ^ line in diameter, and are remark- 

 able for their fimbriated margins, as in L. cestroides^.
