This species is unquestionably distinct from the preceding, 
though much resembling it in general aspect; it is, however, 
much more spinose, its branchlets are thinner and straighter, its 
spines longer and more slender, its leaves smaller and more 
caducous. The internodes are IJ inch apart, the spines Ij-lj 
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 it 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*.
