Siccobaccatus is a genus of Brazilian cacti with two species.[1] Its status as an independent genus has been disputed.

Phylogeny

Based on a phylogenetic study published in 2023, Siccobaccatus was found to be separated from the rest of Micranthocereus, where it had been placed as a subgenus. It was closest to the genus Coleocephalocereus, and the authors suggested that Siccobaccatus should be treated as a subgenus of Coleocephalocereus. The relevant part of their cladogram is shown below:[2]

A 2025 phylogenetic study did not include any Siccobaccatus species, but on the basis of stem anatomy recommended that Siccobaccatus should be kept as a separate genus from Coleocephalocereus.[3]

Species

As of January 2026, Plants of the World Online accepted two species:[1]
