This species is unquestionably distinct from the preceding, 

 though much resembling it in general aspect; it is, however, 

 much more spiny, its branchlets are thinner and straighter, its 

 spines longer and more slender, its leaves smaller and more 

 caducous. The internodes are 1J inch apart, the spines 1J-1J 

 inch long; those of the lateral spinose branchlets are about f 

 inch long ; the floriferous branchlets are 1^ inch long, the axils 

 being from 1 to 3 lines apart. The leaves are 3-5 lines long, 

 and 2 lines broad, upon a petiole 1 line in length ; its flowers 

 are constantly 5-merous ; its calyx, 2 lines long, is double the 

 diameter of that of the former species, and is scarcely contracted 

 in the middle ; externally ifc is very pubescent, its ovary is always 

 3-locular (not 2-celled), and it produces a much larger fruit, 

 which is two or three times the size of that of T. trinervis, being 

 4 or 5 lines long, and 3 or 4 lines in diameter : the ligneous walls 

 of its 3-locular nut are thicker than in the foregoing species. In 

 other respects both kinds are much alike. It appears to grow 

 further away from the coast, upon the more elevated table-lands, 

 and in the valleys of the interior*.
