Haageocereus bieblii is a species of Haageocereus from Peru.[1]
Haageocereus bieblii grows individually with spherical, green shoots up to in diameter that barely protrude from the ground. The 10 to 25 barely recognizable ribs are divided into wart-like humps. The single central spine, which is long and in diameter, may also be missing. The 3 to 10 comb-shaped radial spines are white to dark yellow and long.
The broad, funnel-shaped, white flowers are long and in diameter. Its flower tube is long and slender. The long fruits are greenish red to brownish.[2]
Haageocereus bieblii is distributed in the Ancash region of Peru, northwest of Huaraz, at altitudes of 600 to 1800 meters.
The first description was made in 1995 by Lothar Diers.[3] The specific epithet bieblii honors the German cactus collector Wolfgang Biebl. A nomenclature synonym is Pygmaeocereus bieblii Diers (1995)
