The common morphotype at middle altitudes in Texas and southeastern New Mexico has 0-2(-3) central spines and is called either Echinocereus viridiflorus var. cylindricus (Engelmann) Rümpler or E. chloranthus var. cylindricus (Engelmann) N. P. Taylor. Typical E. viridiflorus (var. viridiflorus), with small stems and relatively pure yellow flowers, extends from central New Mexico and the Texas Panhandle to South Dakota. One of the segregate taxa, Echinocereus chloranthus var. neocapillus D. Weniger, is remarkable for its softly hairy, not sharply spiny, seedlings. Populations of E. viridiflorus from Big Bend National Park, usually with reddish or russet flowers, have been named E. russanthus D. Weniger. Yellow-spined plants may occur at high altitudes. A poorly defined, yellow-spined population near Marathon, Texas, has been named E. viridflorus var. correllii L. D. Benson. Bristly red-spined plants from New Mexico have recently been segregated as E. chloranthus subsp. rhyolithensis W. Blum & Mich. Lange.
Echinocereus viridiflorus in the broad sense may prove paraphyletic with respect to E. davisii, but they are phenologically isolated, with E. davisii flowering earlier and thus appearing reproductively isolated in the wild.
Echinocereus viridiflorus ist eine Pflanzenart in der Gattung Echinocereus aus der Familie der Kakteengewächse (Cactaceae). Das Artepitheton viridiflorus stammt aus dem Lateinischen und bedeutet ‚grünblütig‘. Trivialnamen sind „Brown-Flowered Hedgehog“, „Brown-Spined Hedgehog“, „Golden-Spine Hedgehog Cactus“, „Green-Flowered Torch Cactus“ und „Green Hedgehog“.
Echinocereus viridiflorus wächst einzeln mit aufrecht stehenden Trieben. Sie sind kugelig bis eiförmig, manchmal verlängert oder zylindrisch geformt, 1,2 bis 12,5 Zentimeter hoch und weisen dabei einen Durchmesser von 1 bis 5 Zentimeter auf. Die 6 bis 18 Rippen sind deutlich gehöckert. Die bis zu vier roten, cremefarbenen oder braunen Mitteldornen sind bis zu 2,5 Zentimeter lang. Die 8 bis 24 Randdornen sind gleichfalls rot, cremefarben oder braun und bis zu 1,8 Zentimeter lang.
Die Blüten erscheinen entlang der Triebseiten. Sie sind meist weit geöffnet, trichterig geformt und grün bis gelbgrün. Sie werden 2,5 bis 3,0 Zentimeter lang und im Durchmesser groß. Die Früchte sind kugelig, grün und stark bedornt.
Echinocereus viridiflorus ist in den US-Bundesstaaten South Dakota, Wyoming, Colorado, Kansas, New Mexico, Oklahoma und Texas sowie in den benachbarten mexikanischen Bundesstaaten Coahuila und Chihuahua weit verbreitet.
Die Erstbeschreibung erfolgte 1848 durch George Engelmann.[1] Nomenklatorische Synonyme sind Cereus viridiflorus (Engelm.) Engelm. (1849) und Echinocactus viridiflorus (Engelm.) Pritz. (1855).
Es werden folgende Unterarten unterschieden:[2]
In der Roten Liste gefährdeter Arten der IUCN wird die Art als „Least Concern (LC)“, d. h. als nicht gefährdet geführt.[5]

Echinocereus viridiflorus is a species of cactus known by the common names nylon hedgehog cactus, green pitaya, and small-flowered hedgehog cactus. It is native to the central and south-central United States and northern Mexico, where it can be found in varied habitat types, including desert scrub, woodlands, dry grasslands, and short-grass prairie.[2]
This cactus has a small spherical or cylindrical stem 3 centimeters to over 30 centimeters tall and up to 9 centimeters wide. It is mostly unbranched but it may occur in squat clusters of several branches. The body of the plant is ridged and lined with many areoles bearing spines. The spines may be red, yellow, white, purplish, or bicolored, sometimes with darker tips. The flower is up to 3 centimeters long and has tepals in shades of yellowish, brownish, greenish, or occasionally red, with darker reddish midstripes. The tepals are thin at the tips.[2]
The taxonomy of the species is uncertain, with authors recognizing several varieties which are sometimes treated as separate species. One variety, var. davisii (sometimes called Echinocereus davisii), Davis' green pitaya, is federally listed as an endangered species. This taxon is very small, reaching no more than 3 centimeters tall. It becomes smaller when water is scarce, withdrawing under the ground, sometimes leaving just some spines sticking out.[3][4] It has yellow-green flowers. This rare variety is endemic to Brewster County, Texas, where it grows in beds of Selaginella in rocky soils of novaculite origin.[5] There was only one population known as of 1984, and it probably will not expand its range because it is limited to a specific mineral substrate.[4]

Echinocereus viridiflorus es una especie de planta fanerógama de la familia Cactaceae. Es endémica de Chihuahua, Coahuila de Zaragoza en México y Colorado, Kansas, Nebraska, Nuevo México, Oklahoma, Dakota, Texas y Wyoming en Estados Unidos. Es una especie común que se ha extendido por todo el mundo.
Echinocereus viridiflorus crece individualmente con tallos verticales, globosos a ovoides, a veces alargadoa o cilíndricoa, de 1.2 a 12.5 cm de alto y n un diámetro de 1 a 5 centímetros. Tiene 6 a 18 costillas que son claramente tubérculos. Las areolas con cuatro espinas centrales de color rojo, de color crema o marrón de hasta 2.5 cm de largo. Las 8 a 24 espinas radiales también son de color rojo, crema o marrón y hasta 1.8 cm de largo. Las flores aparecen a lo largo del tallo. Por lo general son muy abiertas, en forma de embudo y de color verde a amarillo-verde de 2,5 a 3,0 cm de largo y de gran diámetro. Los frutos son globosos con espinas, verdes y fuertes.
Echinocereus viridiflorus fue descrita por George Engelmann y publicado en Memoir of a Tour to Northern Mexico: connected with Col. Doniphan's Expedition in 1846 and 1847 91. 1848.[2]
Echinocereus: nombre genérico que deriva del griego antiguo: ἐχῖνος (equinos), que significa "erizo", y del latín cereus que significa "vela, cirio", donde se refiere a sus tallos columnares erizados.
viridiflorus: epíteto latíno que significa "con flores verdes"[3]
