Hab. Rio Negro, North Patagonia : on the sandy plains. 



This and M. ephedroides, the other species of the section, appear to 

 be very closely allied. The pods, as well as the spinescent Broom- 

 like branchlets, of our plant are quite glabrous ; but the capitula are 

 peduncled. and there are a few leaflets. Flowers not seen. The ripe 

 pods, with the replum, break up into indehiscent articles.

There is nothing to add to Guillemin's detailed description of this 

 plant (which is rightly referred to Leuccena by Benth am), except that 

 the mature pods in our specimens are plane.
