Ferocactus chrysacanthus, commonly known as the Cedros barrel cactus, is an endangered species of cactus endemic to the islands of Cedros and West San Benito off the Pacific coast of Baja California, Mexico. It is a solitary-stemmed barrel cactus with a globose to short cylindrical shape, and grows to 1 m (3.3 ft) tall. The yellow to orange flowers bloom from June to July, and mature into yellow fruits.[3][4] Sometimes recognized is the subspecies grandiflorus, which has orange to red flowers up to 6 cm (2.4 in) long and is native to the Vizcaíno Peninsula of Baja California Sur.[1][2]
Taxonomy
The type specimen was collected on Cedros Island in 1894[2]
Infrataxa
- Ferocactus chrysacanthus subsp. chrysacanthus – The autonymic subspecies, endemic to Cedros Island and West San Benito Island in Baja California.[1][4][2]
- Ferocactus chrysacanthus subsp. grandiflorus (G.E. Linds.) N.P. Taylor – A Baja California Sur endemic infraspecies, commonly known as the large-flowered barrel cactus or Vizcaíno barrel cactus that ranges from Bahía Tortugas south to Punta Abreojos on the Vizcaíno Peninsula. It has orange to red flowers. This subspecies is recognized by Kew's Plants of the World Online, the IUCN Red List, and The New Cactus Lexicon. Also known by the basionym Ferocactus fordii var. grandiflorus G.E. Linds. which is recognized by the San Diego Natural History Museum in their 2016 Baja Checklist by Rebman et al. It is recognized by Joël Lodé as synonymous with Ferocactus gracilis.[1][4][2][5][6]
Plants sometimes assigned to Ferocactus chrysacanthus on Isla Natividad, which is located midway between the nominate subspecies on Cedros Island and the subspecies grandiflorus of the Vizcaíno Peninsula, are in fact Ferocactus fordii because of their distinctly purple flowers.[7][8]
