Description
editEchinocereus mapimiensis typically grows in loose clusters up to 60 centimeters in diameter, consisting of up to 50 shoots. These blue-green, cylindrical, soft-fleshed shoots are mostly upright but may overhang with age and shrink in dry conditions. They range from 4 to 30 centimeters in length and 1.5 to 3.5 centimeters in diameter (rarely up to 8 centimeters). The shoots are barely obscured by spines and usually have six blunt, low-humped ribs with circular white areoles. The straight, needle-like spines are blackish or deep red, turning gray or whitish with age, making it hard to distinguish between central and radial spines. The central spines, 1.5 to 2.2 centimeters long, spread out in groups of two to four, while the radial spines, 0.9 to 1.8 centimeters long, spread out in groups of four to eight.
The funnel-shaped flowers are brownish magenta, appearing on the sides of the shoots. They are 3 to 4.5 centimeters long (occasionally up to 5.5 centimeters) and 1.7 to 4 centimeters in diameter, with cream-colored edged bracts. The green fruits are spherical to egg-shaped, 1.5 to 2.1 centimeters long, and 1.2 to 1.5 centimeters in diameter.[3]
Distribution
editEchinocereus mapimiensis is found among shrubs on loamy-sandy alluvial soils in Coahuila, Mexico, within the Mapimi Desert near Bolson de Mapimi, at elevations around 366 meters. Plants are found growing around Grusonia bradtiana, Coryphantha poselgeriana v. valida, Echinocactus horizonthalonius, Thelocactus bicolor, Epithelantha micromeris, Dasylirion longissimum, Mammillaria pottsii, Pelecyphora duncanii, Ibervillea sonorae and Pelecyphora macromeris subsp. runyonii.[4]
Taxonomy
editFirst described by Edward Frederick Anderson, Wendy C. Hodgson, and Patrick Quirk in 1998, the species name "mapimiensis" refers to its occurrence in the Mexican Mapimi Desert.
