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

Cylindropuntia leptocaulis<\/em> is a widespread cholla occurring in a multitude of habitats from 40 to 1500 m elevation from west-central Arizona east through New Mexico and into eastern Texas and far southern Oklahoma, and then south into central Mexico approximately as far as San Luis Potos\u00ed.<\/p>\n

Details<\/h4>\n

G. leptocaulis<\/em> forms shrubs or even small trees up to 1.8 m tall. The stems of G. leptocaulis<\/em>, which are firmly attached, are the thinnest of the Cylindropuntia<\/em> species (2 to 8 cm long by 0.3 to 0.5 cm wide), hence the specific epithet “leptocaulis<\/em>” (“lepto” = slender, “caulis” = stem) and the common name “pencil cholla”. The areoles have only 0 or 1 spine, which is often red-brown with a greyish coat and a yellow tip. Spine sheaths are white, tan, gold, or white, sometimes with red-brown tips. Plants with various spine coloration and spine length can occur in the same population.  Flowers are pale yellow to greenish-yellow with greenish-yellow filaments, yellow styles, and greenish-yellow stigmas. Fruits are often red but sometimes yellow. Fruits are fleshy, spineless, smooth and sometimes stalked (stipitate). G. leptocaulis<\/em> is most often diploid (2n = 22), however, triploids (2n = 33) and tetraploids (2n = 44) have also been found.<\/p>\n

G. leptocaulis<\/em> is known to hybridize with essentially all other Cylindropuntia<\/em> species with which its range overlaps. G. leptocaulis<\/em> \u00d7 G. acanthocarpa<\/em> var. major<\/em> is called G. <\/em>\u00d7tetracantha<\/em>. G.<\/em> \u00d7tetracantha<\/em> is distinguished by having 1-4 spines per areole, tepals which are greenish-bronze to red-magenta, and reddish, slightly tuberculate, slightly spiny fruits. Several other hybrids involving G. leptocaulis<\/em> have been erroneously referred to as G. <\/em>\u00d7tetracantha<\/em>. These include G. leptocaulis <\/em>\u00d7 G. spinosior<\/em>, which have spineless, reddish, strongly tuberculate fruits; and G. leptocaulis <\/em>\u00d7 G. versicolor<\/em>, which have spineless, reddish, smooth, enlarged fruits. G. leptocaulis<\/em> is also known to hybridize with G. fulgida, G. arbuscula, G. kleiniae, <\/em>and G. whipplei<\/em>.<\/p>\nngg_shortcode_0_placeholder\n","protected":false},"excerpt":{"rendered":"
