Soehrensia arboricola is a species of Soehrensia found in Argentina and Bolivia.[1]
Soehrensia arboricola is a shrubby plant that starts upright but later becomes drooping. Its slender, cylindrical, dark green stems can grow over long, with a diameter of, and develop aerial roots. The stems have nine to eleven ribs with almost cube-shaped or conical humps up to high, topped with wooly white areoles. From these areoles, nine to 15 needle-like thorns radiate, one of which is longer, ranging from in length and yellowish to brownish in color. The bell-shaped, white flowers bloom near the top of the shoot, opening at night. They measure long and in diameter.[2]
Soehrensia arboricola is found in southern Bolivia and the Salta province of Argentina at altitudes of 500 to 1000 meters.
Originally described as Trichocereus arboricola by Myron William Kimnach in 1990, the species was named for its epiphytic habitat, with "arboricola" derived from the Latin "arbor" (tree) and "-cola" (dweller).[3] In 2012, Boris O. Schlumpberger reclassified the species into the genus Soehrensia.[4]
