The stems are 4 to 6 cm long by 0.8 to 1.2 cm wide with 7 to 21 yellow to nearly black spines that obscure the stems. The sheaths are loose and yellow. Flowers are yellow-green, tinged purple-red and age to red-brown. Filaments are pale green at the base to purple-tinged distally, with orange-yellow anthers. The styles are cream to pale green, sometimes faintly pinkish-purple distally, with very pale green stigmas lobes. The fruits are yellow, pulpy, and spineless, often in chains of two. <em>Cylindropuntia davisii<\/em> is diploid (2n = 22) and tetraploid (2n = 44).<\/p>\n<p>Curtis\u2019s Botanical Magazine wrote in 1882 that <em>O. davisii<\/em> is: \u201cA small shrubby species, remarkable for the bronzy color of the flowers, which have a peculiar metallic lustre\u2026<em>G. davisii<\/em> is a native of the district of New Mexico, eastward and westward of the Tucumcari Hills\u2026on the head waters of the Canadian River, a branch of the Arkansas.\u201d Britton and Rose reported that the plant was confused with other <em>Cylindropuntia<\/em> species for years.<\/p>\n<p>Dave Ferguson writes:<\/p>\n<blockquote><p><em>Cylindropuntia davisii<\/em> is a species that is known as apparently only two clones that reproduce vegetatively. The more widespread yellow-spined clone is found on the Great Plains from southwest Oklahoma, the Texas Panhandle, and northeast New Mexico, southward apparently to near the Balcones Escarpment in western Texas and across central and southwest New Mexico into northwest Chihuahua (mostly in isolated colonies). It is found in grasslands on sandy (often straight sand) soils.<\/p>\n<p>The red-brown clone is found apparently only in grasslands south of the Davis Mountains in Texas (Jeff Davis, Brewster, and Presidio Counties), and perhaps into Chihuahua. It too favors sandy soils in grassland.<\/p><\/blockquote>\n<p>I&#8217;ve personally never seen seeds on that clone either. Apparently the Great Plains clone is tetraploid (2n = 44), whereas the Trans-Pecos clone is diploid (2n = 22). I&#8217;ve never tried to get the two together to see if they will make seeds if cross-pollinated. A good place to see the Trans-Pecos clone (if our memory is correct) is the Fort Davis cemetery.&#8221;<\/p>\nngg_shortcode_0_placeholder\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Engelmann &amp; J.
