Opuntia aciculata és una espècie de fanerògama de la família de les Cactàcies. És nativa de Nuevo León, Tamaulipas a Mèxic i Texas a EUA.
És un cactus de port arbustiu, tan ramificat que sol ser més ample (fins a 3 m) que alt (no supera el metre). Els segments són de 10-12 cm, ovoides o arrodonits, de color verd pàl·lid o glauc. Grans arèoles molt juntes entre si, amb nombrosos gloquidis. Espines de color marró amb la punta groga, de 3,5 a 5 cm de longitud, primes, aciculars i freqüentment replegades. Flors daurades, estigma amb de 8 a 10 lòbuls verdosos.
Opuntia aciculata va ser descrita per David Griffiths i publicada a Proceedings of the Biological Society of Washington 29(3): 10–11. 1916.[1]

Opuntia aciculata ist eine Pflanzenart in der Gattung der Opuntien (Opuntia) aus der Familie der Kakteengewächse (Cactaceae). Das Artepitheton aciculata bedeutet ‚spitzgestachelt‘.
Opuntia aciculata wächst niedrig strauchig mit niederliegenden Zweigen und erreicht Wuchshöhen von bis zu 1 Meter und mehr sowie Durchmesser von oft bis zu 3 Meter und mehr. Die leuchtend dunkelgrünen, verkehrt eiförmigen Triebabschnitte sind an ihrer Spitze gerundet. Sie sind 12 bis 20 Zentimetern lang. Die darauf befindlichen Blattrudimente sind pfriemlich. Die runden Areolen stehen weit voneinander entfernt. Ihre zahlreichen Glochiden sind dunkelrot und 3 bis 12 Millimeter lang. Die ein bis drei, häufig fehlenden oder nur an den Areolen an den Rändern der Triebsegmente vorhandenen Dornen sind nadelig, dünn und manchmal etwas zurückgebogen. Sie sind gelblich mit einer dunkleren Basis und 3 bis 5,5 Zentimetern lang
Die gelben Blüten erreichen Durchmesser von 8 bis 10 Zentimeter. Die ellipsoiden oder breit birnenförmigen Früchte sind dunkel rötlich purpurfarben.
Opuntia aciculata ist in den Vereinigten Staaten im Bundesstaat Texas sowie in den mexikanischen Bundesstaaten Tamaulipas und Nuevo León verbreitet.
Die Erstbeschreibung erfolgte 1916 durch David Griffiths.[1] Nomenklatorische Synonyme sind Opuntia engelmannii var. aciculata (Griffiths) Bravo (1974), Opuntia lindheimeri var. aciculata (Griffiths) Bravo (1974) und Opuntia engelmannii subsp. aciculata (Griffiths) U.Guzmán & Mandujano (2003).
In der Roten Liste gefährdeter Arten der IUCN wird die Art als „Data Deficient (DD)“, d. h. mit keinen ausreichenden Daten geführt. Die Entwicklung der Populationen wird als stabil angesehen.[2]

Opuntia aciculata, also called Chenille pricklypear,[2][3][4] old man's whiskers, and cowboy's red whiskers,[4] is a perennial dicot and an attractive ornamental cactus native to Texas. It belongs to the genus Opuntia (prickly pear cacti). It is also widespread in Nuevo Leon, Tamaulipas (northern Mexico).
It was reported from Nuevo León, Mexico, according to D. Weniger in 1970.[5] The specific name aciculata derives from many sources: the Latin word acicula which means “a small pin for a headdress”, and the adjectival suffix for nouns atus, meaning possessive of or likeness to something (with, shaped, made), while for verb participles it means a completed action. Chenille prickly pear, one of its vernacular names, comes for the fringe of spines around the edge of the pad.[6] The specific name also means "covered with small pins".[7][8]
It has numerous glochids or microspines, 3–12 mm long, acicular, slender, spreading, forming a dense cluster. They are normally golden yellow to dark red in color. It has often no spines, or rarely one to three, which are reflexed. They are of a yellowish or toasted colour with a brownish base, up to 3 cm in length.[7][9] They are often folded and seemingly deciduous.
It has broad, point-tipped blossoms colored golden yellow, orange, or red and of diameter 8–10 cm. Several sources report the flowers as being yellow in color, but the plants in cultivation usually have bright red-orange flowers, and sometimes the centre is greenish. Petals are broad-rounded or retuse, filaments are yellowish and the stigma dull yellowish with eight to 10 green lobes. They mostly flower in early summer or spring. The plant's fruits are usually pear-shaped, covered with fine spines and glochids, and are purple or green.[5][10]
It is native to Chihuahuan Desert (Texas) and northern Mexico.[6][11][12]
Like its other cactus relatives, this deciduous and succulent species also has its leaves reduced to spines to reduce excess transpiration, which helps it to survive by conserving water in the hot climate of Texas, in southwestern United States, and North Mexico. This adaptation also helps in defending itself from being consumed by any herbivores there.[13] It has the special ability to propagate from woody or softwood stem cuttings. It can even propagate by cuttings of leaf pads at any time in the growing season, allowing the cut surface to callus over before planting. This cactus can survive healthily and produce good many flowers only if it is fully exposed to the sun. They can also tolerate temperatures from −5 to −12 °C.[7]
The fruits are edible and the soft pads (nopales) can be cooked as vegetables. After burning of spines, the pads can serve as a good feed for cattle.[7]
