Introduction<\/h2>\n

Mammillaria heyderi is a short, flat cactus that settles firmly in the ground. Sometimes it is even retracted below the soil surface. In such a condition, it may be difficult to find, especially if it is covered with gravel.<\/p>\n

The Details<\/h3>\n

M. heyderi has six described subspecies: meiacantha, gaumeri, macdougalii, hemisphaerica, applanata, and heyderi. M. heyderi does not form offsets, just solitary stems that are up to 4 inches across. The species has a milky sap. Flowers are often cream colored, but they may be whitish, \u00a0tan, or tan-pink. \u00a0Flowers are not generally showy. The fruits are bright red. M. heyderi grows in grasslands and plains from Arizona to Texas and south to the Yucatan Peninsula.<\/p>\n

The species is easy to grow in pot culture, but it may lose its natural flatness when it is overwatered.<\/p>\n
