Description: Mammillaria haageanaSN|20850]]SN|20850]] subs. conspicua, better known as Mammillaria conspicuaSN|20872]]SN|20872]], can be distinguished from other forms of the Mammillaria haageanaSN|20850]]SN|20850]] complex because is often solitary and has larger stems up to 10-11 cm in diameter.
Habit: Plants usually solitary. Each head is surrounded by a complete ring of star-like pink flowers. There are ample variations among plants from different origin.

Sap: Without latex.
Tubercles: Small, (3-)5-6 mm hight, crowded, conical/pyramidal, four-angled basally.
Axil: Slightly woolly only on new growth, later naked.
Areoles: Small, 2-3 mm, short-elliptic, when young a little woolly, in age glabrate.
Radial spine: 10 to 25, smooth, rigid, acicular, straight or slightly curved, white, radiating, bristly, 3-6 mm long.
Central spine: Usually 2, slender, rigid, straight, not hooked, erect, divergent, dark tipped, turning grey as the ages 6-10 mm long.

Cultivation and Propagation: Mammillaria haageanaSN|20850]]SN|20850]] subs. conspicua is a free-flowering and relatively easy plant to grow.
Exposition: Full sun to light shade.
Watering: Water regularly in summer but do not over-water. Keep dry in winter. Hardy down to -4°C.
Growing tips: It is better that they be repotted regularly. Repotting will increase the number and size of stems, and will increase the number of flowers produced. Repot yearly until it reaches about 3 cm in size, then every two or three years will suffice. Repotting is best done at the end of winter, but it can be done at other time, too. Do not water for a couple of weeks after repotting, in order to reduce risk of root rot via broken roots.
Propagation: Seeds or offsets if available.
