Echinocereus parkeri is a species of cactus native to Mexico.^[2]

Description

Echinocereus parkeri grows in compact cushions or open groups with many shoots. The shoots, which are tapered or cylindrical, can reach up to 15 cm (5.9 in) in length and 2 to 6 cm (0.79 to 2.36 in) in diameter. They have six to ten tuberculated ribs. The one to eight central spines, initially dark but soon turning glassy white to yellowish, range from 2 to 6.5 cm (0.79 to 2.56 in) long. The six to 18 slender, mostly glassy radialal spines are 0.7 to 1.2 cm (0.28 to 0.47 in) long. The funnel-shaped flowers are magenta to deep pink with a white throat. They appear near the tips of the shoots, measuring 4.5 to 5.5 cm (1.8 to 2.2 in) in length and 4.5 to 6 cm (1.8 to 2.4 in) in diameter. The green, spherical fruits have white flesh and are covered with falling, glassy white spines.^[3]
