Notes on Selenicereus triangularis : —The publication year of Plukenet’s Phytographia containing the lectotype was incorrectly given by Doweld l.c as 1696. The original image is available at http://bibdigital.rjb.csic.es/ing/Carga. php?Pagina= A _ PLU _Op_Bot_1/ PLU _Op_Bot_1_049.pdf

Notes on Cereus compressus : — Miller (1768) described Cereus compressus as different from Cereus triangularis . Yet in the protologue of C. compressus , he cited Plukenet’s illustration from the “Phytographia” ( Plukenet 1691). Miller apparently confused the figure of Plukenet, that was originally associated with the name Cactus triangularis by Linnaeus and associated it with his name Cereus compressus . Doweld (2002b) designated Plukenet’s illustration as the lectotypes of both, Cactus triangularis Linnaeus and Cereus compressus Miller Therefore Cereus compressus Miller has to be a homotypic synonym of Cactus triangularis Linnaeus.

The name Cereus triangularis (Linnaeus) Miller is therefore not a combination of Cactus triangularis Linnaeus because it is based on a different type. However it is unclear what exactly Miller based this name on. Therefore Miller’s name was probably not used or mentioned by later authors and should best be formally rejected.
