is 2 lines long ; the tube of the corolla is 2 lines, the lobes of its 

 border 3 lines long ; the tube is encircled in its constricted part 

 by a narrow densely pilose ring, and is bearded internally be- 

 tween the insertion of the stamens; the filaments are thick, 

 fleshy, and geniculated at their origin below the fleshy glands, 

 which form a fornix closing the mouth of the corolla : the berry 

 is crimson, oval, supported by the cup -shaped calyx with its teeth 

 reflexed ; it is 3 lines long and 2 lines broad*.

This is a very distinct species, much resembling L. fuscum, and 

 in all probability is referable to the same section : the branchlets 

 are very flexuose and thick ; the strong axillary spines, which are 

 about i an inch apart, and 1 or 1|^ inch long, bear fascicles of 

 leaves at intervals of every 2 or 3 lines ; the leaves are 4 to 7 

 lines long and 1 line broad; the peduncle is 2 lines long, the 

 calyx about 1^ line in length; the dark-coloured berry 3 lines 

 long and 2 lines in diameter : flowers are wanting in the only 

 specimen I have seenf.
