(Austrocylindropuntia subulata)
Austrocylindropuntia subulata is a species of cactus native to the Peruvian Andes. The Latin specific epithet subulata means "awl-like", referring to the shape of the rudimentary leaves. It is also known by its common names as Eve's pin and Eve's needle. Austrocylindropuntia subulata can reach heights up to 4 metres (13 ft), with numerous branches. The elongated, slightly brittle branches are up to 50 centimetres (20 in) long. The stems are marked by rhomboid to ovate bumps in a few spiral rows. At the tip of each bump is the areole, from which grow one to four straight, grayish-white spines up to 8 centimetres (3 in) long. The awl-like rudimentary leaves are up to 12 centimetres (5 in) long.
