Description: E. dasyacantha is small nipple Cactus forming solitary (or rarely with 2-5 branches) condensed upright cylinders densely covered with white spines with darker tip.
Stems: Spheric, becoming short cylindric in age, 4.5-15 × 3-6 cm
Tubercles: 7-8 × 3-5mm, moderately soft.
Spines: pure white to brown bristly with pink, red-brown to nearly black tips 26-42 per areole; radial spines 21-31 per areole 6-10 mm long; subcentral spines several, appressed; central spines (4-9 per areole, spreading, straight, longest spines 12-17 mm.
Roots: Diffuse or whit ashort taproot.
Flowers: nearly apical, 15-30 mm, outer tepals pinkish conspicuously fringed with darker pinkish to brown or brownish green midstripes.   Stigma lobes are greenish. Blooming: March-July.
Fruits: Bright red, clavate, cylindric, or narrowly ellipsoid, 13-35mm long not very succulent; floral remnant strongly persistent.

Note: This species is frequently  misidentified the ripe fruits, with strongly persistent floral remnant provide the only simple way to distinguish E. dasyacantha from C. duncanii, while the black fresh seeds of E dasyacantha and related species usually provide immediate distinction from E. tuberculosa, E. sneedii, and E. vivipara, which have differently shaped, bright reddish brown fresh seeds. In addition, the greenish stigma lobes of C. dasyacantha, C. duncanii, C. chaffeyi, C. pottsiana, and certain Mexican taxa contrast with the violet or white stigma lobes of C. vivipara, C. sneedii, C. alversonii, and C. hesteri.


Cultivation:
Easy to cultivate in a very gritty substrate with much drainage. Water regularly in summer, but do not overwater (very rot prone), it prefer a completely dry place during winter . An unheated greenhoouse would be perfect. It can survive low temperatures (appr. -12 C). Full sun to light shade.

Propagation: Seeds (no dormancy requirement, they germinate best at  25°C in spring ) or usually by offsets (readily available), or occasionally grafted.
