The conical warts, which are up to 8 millimeters long, are loosely placed together. The axillae bear white wool and yellow nectar glands. The two, rarely four, yellowish-brown central spines are directed downwards and up to 2 centimeters long. The eight to 13 golden-brown, up to 1.2 centimeter long marginal spines are spread out, straight and pimpled.
The short, funnel-shaped, almost wheel-shaped yellow flowers are 5 to 6 centimeters long and reach a diameter of up to 7.5 centimeters. The cylindrical green fruits reach a length of up to 1.5 centimeters.

Taxonomy
The first description as Mammillaria erecta by Ludwig Georg Karl Pfeiffer was published in 1837. The specific epithet erecta comes from Latin, means 'upright' and refers to the upright shoots. Charles Lemaire placed the species in the genus Coryphantha in 1868. Further nomenclature synonyms are Cactus erectus (Lem. ex Pfeiff.) Kuntze (1891) and Glandulifera erecta (Lem. ex Pfeiff.) Frič (1924).
