Pilosocereus brooksianus is a species of flowering plant in the cactus family Cactaceae, endemic to Cuba.[1] It was first described in 1912 by Nathaniel Lord Britton and Joseph Nelson Rose as Cephalocereus brooksianus.[2]
Pilosocereus brooksianus has bluish to glaucous green stems with 8–10 ribs. It has more-or-less upright branches. The areoles have rigid spines up to 3 cm (1.2 in) long. Flowering areoles have dense tufts of silky hairs up to 5 cm (2.0 in) long; non-flowering areoles have few or no such hairs. The flower is 5–7 cm (2.0–2.8 in) long. The outer perianth segments are greenish, the inner ones white. The fruit is glaucous blue-green.[3]
