The plant described by Dr. Clos (Gay's specimen from the 

 same locality), and referred by him to Retamilia, is evidently 

 identical with the above species, which I have characterized from 

 Bertero's collection. I do not adopt his specific name, as all the 

 species of Trevoa are spinigerous *.

This plant greatly resembles T. trinervis in habit, but it has 

 much smaller leaves, and is altogether more spinose. The iu- 

 ternodes are 8-9 lines apart ; the spreading, decussatino- spines 

 are about the same length ; the foliiferous brauchlets are from 

 i inch to 2^ inches long, bearing about two flowers in the lower 

 axils ; the leaves are 3 lines long and U line broad, on a petiole
