Description edit

Echinocereus bonkerae typically grows in loose groups of 5 to 15 green, cylindrical to elongated shoots 12 to 20 centimeters long and 4 to 7.5 centimeters in diameter, partially obscured by thorns. These shoots have 11 to 16 ribs and a single, strong, upright central spine that is white or light gray with a darker tip, measuring 6 to 7.5 millimeters in length. Additionally, there are 11 to 14 spreading, straight, whitish or grayish radial spines that are 1.2 to 2 centimeters long.

The flowers of Echinocereus bonkerae are broadly funnel-shaped and range from magenta to reddish-purple. They appear in the upper half of the shoots, measuring 5 to 6.2 centimeters in length and diameter. The spherical, fleshy fruits start green and later turn red.[5] The chromosome count is 2n = 22.

Distribution edit

This species is commonly found in dry grasslands and in chaparral shrublands in the United States in the Pinal and Santa Catalina Mountains of Arizona, and in the neighboring Mexican state of Sonora growing at elevations of 700 - 2000 meters. Plants grow in sandy-loamy soil and rocky slopes in pinyon-juniper woodlands.[6]

Taxonomy edit

Echinocereus bonkerae was first described by John James Thornber and Frances Bonker in 1932. It was named in honor of Frances Bonker from Pasadena.[7]
