What is Cylindropuntia echinocarpa?<\/em><\/span><\/h3>\n

Cylindropuntia echinocarpa<\/em> is a common cholla in much of the Mojave and Sonoran deserts. It ranges from 50 to 1700+ m in elevation in a wide variety of habitats.<\/p>\n

Details<\/h4>\n

G. echinocarpa<\/em> is morphologically variable, ranging from low, densely branched shrubs to tree-like shrubs to 2 m tall. Stems are 3 to 12 cm long by 1 to 2.5 cm wide with 6 to 22 white, yellow, tan, or occasionally red-brown spines which obscure the stems. Sheaths range from white to yellow and are baggy. The flowers are yellow-green and sometimes tinged orange. Filaments are greenish-white to yellow. The styles and stigmas are white to light green. Fruits are tan, dry, and densely spiny. G. echinocarpa<\/em> is diploid (2n = 22)<\/p>\n

G. echinocarpa<\/em> is known to hybridise with G. acanthocarpa<\/em> (G. \u00d7deserta<\/em>), G. whipplei<\/em>, and G. munzii<\/em>. A single hybrid individual between G. echinocarpa<\/em> and G. ramosissima<\/em> has also been found. In his 1969 book The Cacti of Arizona<\/em>, Benson designated a new taxon Opuntia wigginsii. <\/em>However, it is obvious, even from the type specimen of “O. wigginsii<\/em>,” that it is merely a juvenile form of G. echinocarpa<\/em>. G. echinocarpa<\/em> has been reported as a species parent (i.e., ancestral to) of G. fosbergii<\/em>, but there is no morphological or genetic evidence to support this claim.<\/p>\nngg_shortcode_0_placeholder\n","protected":false},"excerpt":{"rendered":"
