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