- Source: Cacteae
Cacteae is a tribe of plants of the family Cactaceae found mainly in North America especially Mexico. As of August 2018, the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. The main threats to cactus species are poaching, farming, mining developments, and climate change.
Description
The spherical to short columnar plants grow individually or in cushions. Their size varies from dwarf (Turbinicarpus) to huge (Ferocactus). The non-segmented shoot axis is ribbed (Echinocactus), warty (Coryphantha) or ribbed-warty. The size and shape of the warts ranges from long and leafy (Leuchtenbergia) to broad with flat axillae (Turbinicarpus). The areoles are usually oval, ribbon-like, grooved, or dimorphic. The small to medium-sized, regular to rarely bilaterally symmetrical flowers appear below the crown and open during the day. The fruits are fleshy to juicy berry-like, with a scaly to glabrous pericarp. They are bursting to non-bursting or simply crumbling. The small to large seeds vary in shape and surface structure of the seed coat.
Genera
The classification of cacti is in flux; the following list of genera is that from Nyffeler and Eggli (2010).
Acharagma
Ariocarpus
Astrophytum
Aztekium
Cochemiea has been split off since Nyffeler and Eggli (2010)
Coryphantha
Echinocactus
Epithelantha
Ferocactus
Geohintonia
Kadenicarpus
Kroenleinia
Leuchtenbergia
Lophophora
Mammillaria –
Mammilloydia
Obregonia
Pediocactus
Pelecyphora
Sclerocactus
Stenocactus
Strombocactus
Thelocactus
Turbinicarpus – Kadenicarpus and Rapicactus have been split off since Nyffeler and Eggli (2010).
The type genus is Mammillaria.
