==Description== The relatively small, bushy, erect or prostrate species of the genus ''Arthrocereus'' are branched or unbranched. The articulated, cylindrical shoots have 10 to 18 low and narrow ribs on which small areoles sit from which many thin thorns emerge. The elongated, bell-shaped, wide-opening flowers appear near the shoot tip and open at night. The flower cup and the flower tube are covered with wool, hair-like thorns and a few pointed scales.
The spherical to obversely pear-shaped fruits are green and have white flesh. They are thin-walled, non-tearing, and have scales and hair-like spines. The slanting egg-shaped seeds are black.<ref name="Anderson Eggli 2005 p. 80–81">{{cite book | last1=Anderson | first1=Edward F. | last2=Eggli | first2=Urs | title=Das grosse Kakteen-Lexikon | publisher=Ulmer | publication-place=Stuttgart (Hohenheim) | date=2005 | isbn=3-8001-4573-1 | language=de | pages=80–81}}</ref>
