This species differs little from L. florihundumf Dun., but its 

 branches are more intricately spreading and spinose, the bark 

 is darker and more farinose, the leaves are smaller and more 

 oblong ; on the other hand, their axillary nodes are equally ap- 

 proximated, and there is no difference in the size or structure of 

 the flower. The leaves are 1^ to 2 lines long, | line broad; the 

 barren spines are 2 to 3 lines, the gemmiferous 4 to 6 lines or 

 longer; the peduncle | line; the calyx \\ line long, cleft nearly 

 halfway into five very acute teeth ; the tube of the corolla is 2 

 lines, and its segments 1- line long ; it is glabrous, except near 

 the point of insertion of the stamens : the filaments are pilose 

 at their base for a quarter of their length, three of them reach the 

 extremity of the segments, two are shorter ; the slender style is 

 the length of the longer stamens, and is articulated with the 



ovarmm

This species, which I found near Mendoza, in the desert tract 

 called LaTravesia, in many points resembles L. floribundum and 

 rachidocladum,, but is widely distinct. It is remarkable for its 

 almost denuded, slender, spreading branchlets, armed with short, 

 closely-set, neeedle-like spines ; they are generally 2 or 3 lines
