Austrocylindropuntia subulata is a species of cactus native to the Peruvian Andes.

The name subulata comes from the Latin subulate, for awl-like, referring to the shape of the rudimentary leaves.[3] It has the common names "Eve's pin" and "Eve's needle."

Description

Austrocylindropuntia subulata can reach heights up to 4 meters, with numerous branches. The elongated, slightly brittle branches are up to 50 centimeters 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 centimeters long. The awl-like rudimentary leaves are up to 12 centimeters long.

Flowers are up to 6 centimeters long. The long, warty hypanthium is covered by rudimentary leaves up to 2 centimeters long. The fruit are ovoid or club-like and sometimes thorny. They are up to 10 centimeters long.

Classification

The first description as Pereskia subulata took place in 1845 by Friedrich Mühlenpfordt.[4] Curt Backeberg classified it in the genus Austrocylindropuntia in 1942.[5]
