Latin pilōsus ‘hairy’ + Cereus, the name of a genus of columnar cacti and a designation for columnar cacti in general. A replacement name for Pilocereus intended to be “as similar as possible” (Byles & Rowley in Cact. Succ. J. Gr. Brit. 17: 32. 1955) to that name.
Byles & Rowley (l.c.) suggested Pilosocereus and Pilatocereus (Latin pĭlātus ‘grown hairy, armed with javelins’) as possible replacement names for Pilocereus. Curt Backeberg apparently preferred Pilosocereus: “Mr. C. Backeberg has requested us to make valid the new name Pilosocereus for it in time for inclusion in his new monograph of the Family” (Byles & Rowley in Cact. Succ. J. Gr. Brit. 19: 66. 1957).
Note that the first part of Pilocereus is not Latin pĭlus ‘hair’, but Greek pilos ‘woolen cap’.
