Cereinae Explained

Cereinae is a subtribe of cacti in the tribe Cereeae, subfamily Cactoideae. It is one of the three subtribes into which the tribe Cereeae is divided, the others being Rebutiinae and Trichocereinae.

Genera

14 genera were firmly included in subtribe Cereinae in a 2021 study. This included Stephanocereus, treated as a synonym of Arrojadoa by Plants of the World Online . Espostoopsis was not included in the 2021 study, but was noted to have been placed in Cereinae in many previous studies, including that by Lendel in 2013.^[1] Serrulatocereus was also not included in the 2021 study. It may not be distinct from Cereus as molecular phylogenetic studies have placed in that genus, a placement accepted by some sources.^[2]
