Ferocactus emoryi, known commonly as Emory's barrel cactus, Coville's barrel cactus and traveler's friend, is a barrel cactus in the genus Ferocactus.
Description
Ferocactus emoryi is spherical or cylindrical solitary barrel cactus, light green to glaucous, reaching a diameter of 60–100 centimetres (24–39 in) and a height of 2–2.5 metres (6 ft 7 in–8 ft 2 in). It has 15 to 30 ribs with tubercles, especially in the juvenile stage. The spines are white to reddish. The central spine is very strong, 4–10 cm long, while the seven to twelve radial spines reach lengths of up to 6 cm. The large and funnel-shaped flowers are usually red or yellow, reach lengths of up to 7.5 centimeters and have a diameter of 5 to 7 centimeters. The fruit is ovoidal, about 5 cm long. The subspecies F. e. subsp. rectispinus has been found with center spines as much as 25 cm (9.8 in) long,[2] to even 32 cm (13 in).[3] These are the longest spines of any cactus.[citation needed]

Taxonomy
The species was first described as Echinocactus emoryi in 1848 by George Engelmann who named the plant after American Major William Hemsley Emory, who was responsible for the surveying work on the Mexican border from 1850 to 1854. Charles Russell Orcutt placed the species in the genus Ferocactus in 1926.[6]
