Accepted Scientific Name: Mammillaria brandegeei (J.M.Coult.) K.Brandegee
Erythea 5: 116 1897
Origin and Habitat: Mammillaria brandegeeiSN|23737]]SN|23737]] is endemic to the Mexican states of Baja California and Baja California Sur (Vizcaíno desert region of central Baja California).
Altitude range: This species occurs at elevations from sea level to about 200 metres above sea level.
Habitat and Ecology: It occurs among rocks but also among other vegetation and has often its vegetative body underground, exposing on the top of the plant at the soil surface. During drought it actually shrinks down into the soil, where the microclimate is much more equitable. It is often found growing at the base of larger plants together with other succulent species including Bergerocactus emoryiSN|5475]]SN|5475]], Lophocereus schottiiSN|8344]]SN|8344]], Echinocereus maritimusSN|8323]]SN|8323]], Ferocactus fordiiSN|11980]]SN|12330]], Ferocactus viridescensSN|13617]]SN|13617]], Ferocactus gracilisSN|12330]]SN|11980]], Idria columnarisSN|30207]]SN|30207]] and many species of Dudleya. Parts of the species range are probably affected by human activities, however, it is a wide-ranging plant that has only localized threats, and occurs within protected areas.

Description: Mammillaria brandegeeiSN|23737]]SN|23737]] is a great looking cactus, solitary or eventually forming clusters of 2 to 8, but is sensitive to low temperatures and needs extra heat in winter. Four subspecies recognized, the nominate, gabbii (J.M. Coult.) D.R.Hunt, lewisiana (H.E.Gates) D.R.Hunt and glareosa (Boed.) D.R.Hunt.
Stem: Cylindric to globular, flattened, dark green, to 9 cm in diameter.
Tubercles: Firm, square and angled basally, conical above with latex, axils woolly without hairlike bristles.
Radial spines: 9 to 16, whitish to yellowish brown, with dark tips, needle-like, 8 to 10 mm long stiff, straight.
Central spines: 2-4, sometimes only 1 in an occasional areola, usually a little longer and darker than the radials, reddish brown with darker tips, straight, stout, 10-12 mm long.
Flowers: Greenish-yellow, brownish yellow, to yellow 15-21 mm long; outer perianth-segments ovate, striate, ciliate; inner perianth-segments greenish yellow with a reddish-brown midstripe, narrower than the outer, entire.
Blooming season: Spring (April in habitat).

Cultivation and Propagation: Mammillaria brandegeeiSN|23737]]SN|23737]] is slow-growing, and not especially easy to grow, but some plants will offset readily, and clumps can be produced in a few years.
Soil: Use pot with good drainage and a very porous mineral-based potting mix.
Waterings: Potted plants are quite wet-sensitive, especially in light of its small root system. Water sparingly during the growing season, keep very dry in winter.
Fertilization: Feed with a high potassium fertilizer in summer.
Hardiness: Usually it is recommended to overwinter this plant in a bright and warm greenhouse with at least 8-10° C, but it has proved to be quite frost resistant (if kept dry, it's hardy as low as -5° C).
Exposure: Strong light is required for flowering.
Propagation: Direct sow after last frost, or use cuttings.
