description
Mammillaria roemeri grows individually or in branches with beet roots up to 10 centimeters laterally. The depressed, spherical shoots are only 1 to 2 centimeters high with a diameter of up to 3.5 centimeters. The warts, which are only 3 to 4 millimeters long, are soft fleshed. They are placed relatively densely, somewhat truncated, dark green to blue-green and without milky sap . Central spines are completely absent. The 25 to 32 radial spines radiate horizontally in a star shape. They stand in a row and are soft, very downy, glassy white and 1.5 to 2.3 millimeters long.
The wide open funnel-shaped flowers are whitish to cream-colored with a greenish throat. They are 1.2 to 1.5 inches long. The spherical green fruits , some of which are sunk into the plant body, are sparse. They each contain 4 to 14 black seeds .
