Description

Mammillaria uncinata typically grows alone, but can also form clusters. Its flattened, spherical to globular shoots are dark blue-green in color, measuring {{cvt|6 to 10|cm}} in height and {{cvt|8 to 10|cm}} in diameter. The plant features firm, pyramidal tubercles that are angular at the base and exude a milky sap. The axils of the tubercles are initially covered with wool, which later becomes bare.

The cactus has a central spine that is pinkish-gray to dark purple-brown, with a dark tip, and can be up to {{cvt|1|cm}} long. It also has 3 to 6 radial spines that are straight or slightly curved; the uppermost ones are shorter and stronger. These radial spines are pinkish to grayish-white and measure about {{cvt|5 to 6|mm}} in length.

The flowers are yellowish or white with a reddish-brown central stripe. They are {{cvt|1.5 to 2|cm}} long and up to {{cvt|1.5|cm}} in diameter. The fruits are club-shaped, purple-red, and grow up to {{cvt|1.8|cm}} long. They contain brown seeds.{{cite book | last=Anderson | first=Edward F. | title=Das große Kakteen-Lexikon | publisher=Ulmer | publication-place=Stuttgart | date=2011 | isbn=978-3-8001-5964-2 | language=de | page=413}}
