Pelecyphora robbinsiorum is a species of flowering plant in the family Cactaceae.
Pelecyphora robbinsorum grows solitary. The shoots, which often barely protrude from the ground surface, reach heights of 2 to 6 centimeters and the same diameter. Their tightly packed warts are 5 to 8 millimeters long. Central spines are usually not present. The eleven to 17 white marginal spines have a darker tip and are occasionally twisted. They are 0.3 to 1.8 centimeters long.
The flowers are yellowish green to pink. They are 1.8 to 2 centimeters long and reach a diameter of 1.2 to 1.5 centimeters. The orange-red, short cylindrical fruits are 6 to 8.5 millimeters long. [2]
Pelecyphora robbinsorum is widespread in the United States in Cochise County in the state of Arizona and in the Mexican state of Sonora.
The first description as Cochiseia robbinsorum by W. Hubert Earle was published in 1976. [3] The specific epithet robbinsorum honors James A. Robbins and his sons Jimmi and John, who discovered the species. David Richard Hunt placed the species in the genus Escobaria in 1978. [4] David Aquino & Daniel Sánchez moved the species to Pelecyphora based on phylogenetic studies in 2022. [5] Further nomenclature synonyms are Coryphantha robbinsorum (W.H.Earle) A.D.Zimmerman (1978), Neobesseya robbinsorum (W.H.Earle) Doweld (2000) and Escobaria robbinsiorum (W.H.Earle) D.R.Hunt (1978).
