Mammillaria theresae

It is a small cylindrical cactus, olive green in color with typical magenta shades, which does not grow over 5 centimeters in length, but generally tends to cluster with growth. It has many small conical tubercles, from which microscopic white spines emerge that look like a hairy starfish. The main reason for which this Mammillaria is highly appreciated is undoubtedly its funnel-shaped pink inflorescence, even larger than the stem.
