Succulents Taxonomy

Succulents belong to a diverse group of plant species known for their ability to store water in their leaves, stems, or roots, allowing them to thrive in arid and semi-arid environments. Their taxonomy provides insights into their classification and relationships within the plant kingdom.

Kingdom: Plantae Succulents, like all plants, belong to the kingdom Plantae, which encompasses all multicellular, photosynthetic organisms on Earth. This kingdom is the foundation of plant life.

Phylum: Angiosperms (Angiospermae) Succulents are part of the phylum Angiosperms, commonly referred to as flowering plants. Angiosperms are characterized by the presence of flowers, which are reproductive structures responsible for producing seeds enclosed within fruits.

Class: Eudicots (Eudicotyledons) Within the phylum Angiosperms, succulents fall under the class Eudicots. Eudicots are one of the two major groups of flowering plants, with the other being monocots. Eudicots are distinguished by their two seed leaves (cotyledons) and various other floral characteristics.

Order: Various Orders Succulents are further classified into various orders within the class Eudicots. Some of the well-known orders that include succulent species are Caryophyllales (which includes Cactaceae or cacti), Lamiales (which includes the Lamiaceae family), and Asparagales (which includes Agave and Aloe species).

Family: Diverse Families Succulents are found in a wide range of plant families. For example:

  • Cactaceae: This family includes well-known succulents like cacti, characterized by their distinctive spines and globular shapes.
  • Crassulaceae: Known as the stonecrop or orpine family, this group includes many popular succulents such as Echeveria and Sedum.
  • Agavaceae: This family includes the Agave genus, known for its rosette-forming succulents like Agave americana.
  • Aloaceae: The Aloe family includes species like Aloe vera, renowned for its medicinal properties.
  • Euphorbiaceae: Some succulent euphorbias belong to this family, known for their unique forms and latex-containing stems.

Genus and Species The most specific level of classification for succulents is the genus and species. For instance, the Aloe vera plant’s scientific name is Aloe barbadensis miller, where “Aloe” is the genus and “barbadensis miller” is the species.
