[2] Echinocereus spinigesmatus usually branches and forms loose groups consisting of seven to ten shoots.

The ten to 13 slender and yellowish marginal spines are 0.3 to 2.3 cm (0.12 to 0.91 in) long.

The funnel-shaped flowers are slightly pinkish lilac to light purple.

[3] Echinocereus spinigesmatus is distributed in the Mexican states of Zacatecas and Jalisco.

[4] The specific epithet spinigtematus is derived from the Latin words spina for 'sting' or 'thorn' and gemmatus for 'to have buds'.
