Notes

In the second half of the twentieth century, Lemaireocereus was referred to as synonym of Pachycereus (see there) by Buxbaum (1961), Bravo-Hollis (1978), and Gibson & Horak (1978), based on similar floral morphology. Phylogenies based on molecular (Arias & al. 2003) and structural data (Arias & Terrazas 2006) consistently have revealed that Lemaireocereus is an early diversified lineage within Pachycereinae. Lemaireocereus should be restricted to species with rounded ribs, terminal flowers with long hairs and bristles, fruit with irregular dehiscence, and red pulp (Arias & Terrazas 2009; Arias & al. 2012).A,B,C,D,E,F,G,H

Taxon standing

Category E. No assessment of monophyly has yet been possible, because only a few species were sampled or no phylogenetic study has been conducted so far.
