Description

Echinocereus barthelowianus often forms clusters up to 80 cm (31 in) in diameter. [3] Its cylindrical, upright shoots grow up to 30 cm (12 in) long and 3.5 to 5 cm (1.4 to 2.0 in) in diameter, mostly covered by dense thorns. It has eight to ten slightly tuberous ribs with large areoles. [3] The thorns, pink to red when young, darken to black with age. [3] The five to nine strong, straight central spines can reach up to 7 cm (2.8 in) long, and the 18 marginal spines are 1 to 2 cm (0.39 to 0.79 in) long. [3]

The broad, funnel-shaped flowers are lavender and appear from the shoot tips to the base. They grow up to 5 cm (2.0 in) long and 4 to 6 cm (1.6 to 2.4 in) in diameter. [3]

Distribution

Echinocereus barthelowianus is widespread in Baja California Sur, particularly around Isla Magdalena and neighboring islands growing on rocky hillsides at elevations of 10 to 300 m (33 to 984 ft). Plants grow among Cochemiea halei , Cochemiea poselgeri , Cochemiea dioica , Cochemiea schumannii , Stenocereus eruca , Stenocereus gummosus , Cylindropuntia molesta , Cylindropuntia cholla , Cylindropuntia tesajo , Opuntia pycnantha , Opuntia invicta , Pachycereus pringlei , Stenocereus thurberi , and Lophocereus schottii .

Taxonomy

Nathaniel Lord Britton and Joseph Nelson Rose first described this species in 1922 in the third volume of The Cactaceae. [5] The specific epithet "barthelowanus" honors Captain Benjamin Barthelow, who accompanied Rose in exploring the Lower California coast on the US steamship Albatross.
