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
[edit]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,[1] to even 32 cm (13 in).[2] These are the longest spines of any cactus.[citation needed]
