This plant differs from the preceding in its slender, scandent, 
flexuose branches, with internodes f-l^ inch long; the leaves 
are much larger, being 2-2^ inches long, and inch broad ; 
the petiole is f inch long ; the very obtuse subrecurved spine is 
about 1 line long.

This species is sufficiently distinct from the two preceding. 
It appears to have a simple and erect stem, without any ten- 
dency to become scandent ; the stem is flexuose, with internodes 
5-8 lines long, and infrapetiolar spines scarcely a line in length : 
its leaves are 10-18 lines long, 2-3 lines broad, on petioles 
scarcely 1 line long ; the peduncle is 1 line long, with an almost 
capitate head of few flowers, 1 line in diameter ; the flower in 
bud is ^ line in diam.; its four sepals are fleshy, glabrous inside; 
its cup-shaped corolla has a slightly 4-lobed border ; the fila- 
ment, which scarcely exceeds it in height, bears a 4-lobed, 
4-celled anther.
