Euphorbia tirucalli

Pencil Cactus

The primary subject is a succulent plant identified as *Euphorbia tirucalli*. This identification is based on its distinctive morphology, which includes numerous green, cylindrical, pencil-thin stems that branch profusely, creating a dense, shrub-like form. The plant appears leafless, which is characteristic of this species as its leaves are tiny and ephemeral, with the green stems performing photosynthesis. The overall growth habit and stem structure are classic for the Pencil Cactus.

Overview

Euphorbia tirucalli is a tree native to Africa that grows in semi-arid tropical climates. A hydrocarbon plant, it produces a poisonous latex that can cause temporary blindness.
