Welcome to M&J Cactus Wiki The Comprehensive Online Encyclopedia of Cactaceae based on the Taxonomy of Joël Lodé (2015-2026)

Overview

Welcome to the official knowledge base of M&J Cactus. This project aims to document the family Cactaceae through the lens of modern molecular phylogenetics. We strictly follow the taxonomic revisions of Joël Lodé, which represent the most up-to-date scientific understanding of cactus evolution and relationships.

Classification by Joël Lodé

The family Cactaceae is divided into four main subfamilies. Explore the genera within each group:

Pereskioideae

• The most primitive cacti with true leaves.
• Key Genera: Pereskia, Leuenbergeria.

Maihuenioideae

• Small, succulent shrubs from the Andes.
• Key Genera: Maihuenia.

Opuntioideae

• Characterized by glochids and specialized seed structures.
• Major Tribes: Cylindropuntieae, Opuntieae, Tephrocacteae.

Cactoideae

• The largest subfamily, containing the vast majority of desert and epiphytic cacti.
• Key Tribes (Lodé System):
  • Cacteae – (e.g., Mammillaria, Ariocarpus, Thelocactus)
  • Pachycereeae – (e.g., Pachycereus, Cephalocereus, Carnegiea)
  • Trichocereeae – (e.g., Lobivia, Rebutia, Trichocereus)
  • Cereeae – (e.g., Melocactus, Cereus, Pilosocereus)
  • Hylocereeae – (Epiphytic cacti like Selenicereus)
  • Blossfeldieae – (The unique genus Blossfeldia)

Why Lodé Taxonomy?

Traditional systems (like Hunt or Backeberg) relied mostly on morphology (how plants look). The Lodé system integrates DNA sequencing (phylogenetics), providing a more accurate map of how cacti are actually related.

• Synonymy: We provide extensive cross-references for old names to help collectors find the modern equivalents.
• Global Standards: Adopted by serious collectors and botanical institutions worldwide.
