Diagnosis:—Mammillaria breviplumosa is similar to M. sanchez-mejoradae Rodrigo González. (1992: 55) and M.
hermosana Linzen, Ten Hoeve & Mart.-Avalos in Linzen (2014: 2–9) from which it differs in having a higher number
of radial spines (40‒55 vs. 30‒40 and 22‒30 respectively), the cylindrical tubercles with truncate apexes (vs. conical
and cylindrical in the other two species), the papillose epidermis of the tubercles (vs. naked), the smaller flowers (14‒16
mm in diameter vs. 16‒20 mm in M. sanchez-mejoradae, and 20‒23 mm in M. hermosana), smaller and oval areoles
(0.8‒1.0 × 0.5 vs. 1.3‒1.5 circular, and 1 × 2 mm circular), and the fruit ovoid, 3‒5 × 2‒3 mm (vs. subsphaerical, and
3‒8 mm in diameter in both the other two species). |
