Cylindropuntia ganderi, also known as Gander cholla and Gander's buckhorn cholla, is a cholla native to the Sonoran Desert of Baja California, Mexico, and the adjacent border area of southern California, US where it intergrades with Cylindropuntia californica.

Cylindropuntia ganderi - Wikipedia

C. ganderi is an erect, basally branching shrub growing to 1.5 m tall. The stems are firmly attached and 5 to 26 cm long by 1.7 to 4.5 cm wide. Each areole has 11 to 28 white, yellow, tan, or occasional red-brown spines which obscure the stems. The spines age brown to black, and the sheaths are white to golden. The flowers are yellow-green, often with red tips. The filaments are yellow-green, the styles are cream to yellow, and the stigma is white to greenish. The fruits are yellowish, dry, and spiny. Cylindropuntia ganderi is diploid (2n = 22).

Besides the typical variety, one additional variety, Cylindropuntia ganderi var. catavinensis, is also currently recognized. This variety occurs in central Baja California, being particularly abundant near the town of Cataviña. It differs from the typical variety in having more spines, which are cream to pinkish-orange in color, along with its more southern distribution which does not overlap with the typical variety.

Cylindropuntia ganderi var. ganderi intergrades with Cylindropuntia californica var. parkeri at the north end of its range. Cylindropuntia ganderi was originally described as a variety of C. acanthocarpa. However, C. ganderi lacks the variable flower coloration, red filaments, and pink to red style of C. acanthocarpa. It is, therefore, most likely much more closely related to C. californica and C. echinocarpa.
