description
Thelocactus garciae grows individually or in smaller groups and has a body up to 8 centimeters high with a diameter of up to 12 centimeters. The 8 to 13 ribs are completely dissolved in warts, which are arranged in a spiral and are 1.5 centimeters high and wide at the base. The areoles are 3 to 4 millimeters long and sit in the more flowered part on the inside of the warts. The radial spines are divided into two types: 7 heavy, needle-shaped spread on the lower half of the areoles and 7 fine needle-like, almost bristle-shaped spread on the upper half of the areoles. The 4 central spines are between 3 and 6.7 inches long. The upper ones are matt gray to brownish and partly curved downwards.
The flowers are 3 to 4 inches long and up to 5.5 inches wide. The flower color varies between pale translucent pink, pink, pink with a darker central stripe and, more rarely, pale translucent cream color. The fruits are purple-red and 2 inches long and 1.3 inches wide. They have triangular scales and spring up dry. The seeds are large, 2 millimeters long and up to 5 millimeters thick. They are irregularly curved with a black, humped testa .
