Habitat:

E. coptonogonus is native to Mexico Central, Mexico Gulf, Mexico Northeast and Mexico Southwest where the plant grows in semi-desert areas.

Description:

E. coptonogonus is a globular succulent belonging to the Cactaceae botanical family. The plant grows solitary and has small dimensions, it can reach up to 10 cm in height. The stem is globular, barrel-shaped, greyish green in color, arranged in 10-15 ribs made of tubercles. The ribs are thick, of triangular section, and bear areoles. The areoles are abundantly woolly and 3-5 spines are inserted on them. The spines are sharp, stout, incurved yellowish in color and 5 cm long. Blooming occurs in spring and blossom are borne at the apex of the plant. The flowers are funnel-shaped, purple in color with white margins.

Cultivation:

This is a slow growing plant, easy to cultivate. The plant needs a full light sun exposure but is recommended to avoid direct sun-light in the hottest periods. The plant does not like temperatures below 5°C so it needs to be placed indoors in the coldest periods. The soil should be mixed with pumice, clay and loam to allow the drainage and prevent the root rot, the plant is prone to it indeed. Remember to use a perforating pot to drain excess water. Watering can be done regularly in Spring and Summer: during the vegetative period you can water the plant (every 7 days), checking that the soil is completely dry before watering again; in winter you should stop the watering to allow the plant to enter dormancy. If you want a faster and lush growth you can fertilize the plant once a month during the growing season with the specific fertilizers for cacti; stop fertilizing throughout the winter. If the pot starts to be too small for the plant you can repot the plant in a pot 2 cm wider. Repotting should be done early in the growing season with fresh new potting soil. Be careful to red spiders and mealy bugs.

Propagation:

Propagation can be done by cutting or by seed. By cutting you can make the cut during the spring and then let the cutting dry; after a few days the cut surface will dry and a callus will form, then place the cutting in a mixture of sand, soil and pumice. To increase the success of propagation you can make two or more cuttings at the same time. For cuttings it is recommended temperatures around 20 °C. By seed it is very simple to propagate the plant, it is enough to sow the seed in a sandy loam soil and keep it with a high level of humidity and at temperature of 14 C°.

Curiosity:

As for other types of cacti, the name comes from the greek echinos (porcupine) combined, in this case, to the Latin term fossula (small pit). In fact, we will see that these plants are characterized by deep furrows between the various ribs, which cover their surface.
