M. supraflumen ML 295 Ferreria, Jalisco, Mexico 1550m
This species (previously considered independent ) is now included with many others in Mammillaria nunezii.
Description: M. supraflumen is a small cactus covered with wool, spines and showy flowers in June. It is usually solitary, but occasionally forms offsets.
Stem: Pale green, spherical to cylindrical, sunken apically, 30 - 100 mm high, 40 - 70 mm in diameter (or more in cultivation). Without latex.
Tubercule: Conical to four-angled, pyramidal, firm, with a humpbacked epidermis, 7 - 9 mm long and 5 - 7 mm in diameter.
Axil: With a few bristles and some wool.
Areoles: Large, white and woolly.
Radial spine: 20 - 25, stiff, bristle-like, straight, expanding, the uppermost being the shortest, glassy white, 3 - 7 mm long.
Central spine: 5 - 9, needle-like, straight (sometimes one is hooked), brown to reddish, 7 - 15 mm long.
Flower: Funnel-form, dark carmine to magenta, 13 - 15mm long and 10 - 12 mm in diameter.
Fruit: Ovoid to club-shaped, carmine, 10 - 15 mm long and 6 - 8 mm wide, ripens 12 - 14 months after flowering. (while in Mammillaria nunezii the fruit is greenish-white, tinged with pink)
Seed: Brown, round to club-shaped, 0,9 mm long and 0,8 mm in diameter, testa striated, hilum subbasal.
Blooming season (Europe): April - July.
Comments: This plant is now referred to: M. nunezii ssp nunezii. The differences with M. nunezii ssp nunezii are very few: only the fruit's colour, and its having fewer spines.
Cultivation: An easy-to-grow and easily flowering species, but not a fast grower, that may make large clumps given the best conditions. Some plants will offset, and moderately large-sized clumps can be produced in a few years.
Water regularly in summer, but do not over-water (rot prone). Use a pot with good drainage and a very porous potting media, and keep dry in winter. Feed with a high potassium fertilizer in summer. Avoid frost. Reputedly sensitive to low temperatures, but less so if kept on the dry side prior to, and during, cold weather. Outside full sun or afternoon shade, inside it needs bright light, and some direct sun. Tends to get yellowish in strong light, which encourages flowering and heavy wool and spine production.
Propagation: Direct sow after last frost, or division of larger plants.
