Description

Echinocereus laui forms clusters of up to 20 cylindrical shoots, each reaching up to 10 cm (3.9 in) in height and 4 cm (1.6 in) in diameter. [3] These shoots have 14 to 16 low ribs with small cusps.[ citation needed ] The plant features four reddish-brown central spines, up to 3 cm (1.2 in) long, and 18 to 21 bristle-like white radial spines, 5 to 10 mm (0.20 to 0.39 in) long. [3]

Its narrow, funnel-shaped pink flowers bloom near the tips of the shoots, measuring 3 to 6.2 cm (1.2 to 2.4 in) in length and 4 to 7.2 cm (1.6 to 2.8 in) in diameter. [3] The spherical fruits are brownish-green, covered with wool and thin brown thorns. [3]

Distribution

Echinocereus laui is found in oak forests, rock outcrops, and grasslands in eastern Sonora and western Chihuahua in Mexico, within the Sierra Madre Occidental at elevations of 1,480 to 1,800 m (4,860 to 5,910 ft). It is found growing along with Cochemiea barbata . [4]

Gerhard R. W. Frank first described the species in 1978, naming it after Alfred Bernhard Lau, its discoverer. [5]
