It is known from only from the Grand Canyon and in Peach Springs Canyon, on the Hualapai Reservation in Mohave County. It grows in desert scrub on limestone ledges and hilltops.[3] The natural range of the species is fairly small, but it is locally abundant and growing in an isolated area with few threats to the species survival.[4]Cylindropuntia abyssi has branched stems up to 1 m (40 inches) tall. Stem segments are somewhat detachable, up to 14 cm (5.6 inches) long. Flowers are pale greenish-yellow. Fruits are dull yellow, dry, spineless or nearly so, with brown seeds.[5][6][7] References1. ^Tropicos 2. ^The Plant List 3. ^Flora of North America 4. ^IUCN (International Union for Conservation of Nature and Natural Resources), Red List of Threatened Species 5. ^Backeberg, Curt.
