Description
Harrisia pomanensis sometimes grows a bit bushy. The more or less upright, sometimes arched or prostrate, blue-green or gray-green, glaucous shoots are almost round and have a diameter of 2 to 4 centimeters. There are four to seven blunt, rounded, non-humped ribs. The needle-like, initially reddish to almost white thorns later turn gray with a black tip. The individual central spine is 1 to 2 centimeters long. The six to eight marginal spines reach a length of up to 1 centimeter.
The flowers reach a length of up to 15 centimeters. The spherical, slightly bumpy red fruits have a few scales.{{cite book | last=Anderson | first=Edward F. | last2=Eggli | first2=Urs | title=Das grosse Kakteen-Lexikon | publisher=Ulmer | publication-place=Stuttgart (Hohenheim) | date=2005 | isbn=3-8001-4573-1 | language=de | pages= 338–339}}

Taxonomy
The first description as Cereus pomanensis was made in 1897 by Frédéric Albert Constantin Weber in Karl Moritz Schumann's complete description of cacti.{{cite book | last=Schumann | first=Karl Moritz | last2=Hirscht | first2=Karl. | title=Gesamtbeschreibung der Kakteen (Monographia cactacearum) /von Karl Schumann. | publisher=J. Neumann | publication-place=Neudamm [Dębno, Poland?] | year=1899 | doi=10.5962/bhl.title.10394 | page=}} The specific epithet pomanensis refers to the occurrence of the species near Pomán in the Argentine province of Catamarca. Nathaniel Lord Britton and Joseph Nelson Rose placed the species in the genus Harrisia in 1920.{{cite book | last=Britton | first=Nathaniel Lord | last2=Eaton | first2=Mary E. | last3=Rose | first3=J.
