Prunus fasciculata és una espècie de planta de la família de les Rosàcies. És un arbust caduc o perenne natiu dels deserts d'Arizona, Califòrnia, Nevada i Utah.[1][2][3] Prefereix terrenys rocosos o sorrencs fins a una altitud de 2200 msnm.
Arriba a mesurar fins a 2 m d'alçada, podent ser excepcionalment majors, amb gran ramificació i espinós.[4] La seva escorça és de color gris i glabre.
Les fulles tenen 5-10 mm de longitud, lanceolades, linears amb pecíol curt. Les flors són petites de 3 mm de color blanc i creixen des de les fulles axil·lars. El fruit és una drupa d'un centímetre de longitud, ovoide, de color marró pàl·lid i pubescent.[5][6]
Prunus fasciculata va ser descrita per Asa Gray i publicada a Proceedings of the American Academy of Arts and Sciences 10: 70, l'any 1874.[7]

Prunus fasciculata, also known as wild almond, desert almond, or desert peach[2] is a spiny and woody shrub producing wild almonds, which is native to western deserts of North America.
Prunus fasciculata grows up to 2 metres (6+1⁄2 feet) high, exceptionally to 3 metres (10 ft), with many horizontal (divaricate) branches, generally with thorns (spinescent), often in thickets. The bark is gray and without hairs (glabrous).[3]
The leaves are 5–20 millimetres (1⁄4–3⁄4 inch) long, narrow (linear), with a broad, flatten tip that tapers to a narrow base, (spatulate, oblanceolate), arranged on very short leaf stem (petiole) like bundles of needles (fascicles). Sepals are hairless and without lobes or teeth. The flowers are small and white with 3-mm petals, occurring either solitary or in fascicles and are without a petal stem (subsessile) growing from the leaf axils. They are dioecious. Male flowers have 10–15 stamens; female, one or more pistils. The plant displays numerous fragrant flowers from March to May, which attract the bees that pollinate it. The drupe is about 1 centimetre (1⁄2 in) long, ovoid, light brown and pubescent with thin flesh.[3][4][5]
The species lives many years (is perennial), and drops its leaves (deciduous).[6][7][8]
The plant was first classified as Emplectocladus fasciculata in an 1853 paper by John Torrey based on a collection of the plants of California acquired during the third expedition of John C. Fremont in 1845;[9] whence the synonym Emplectocladus fasciculata (Torr.)[10] The work was illustrated by Isaac Sprague. Torrey devised the genus Empectocladus to comprise a few desert shrubs. According to Silas C. Mason[11] the genus has
According to George Bentham and Joseph Dalton Hooker[12] the name fasciculata means that the leaves are in fascicles, or little bundles:
However, Asa Gray publishing in 1874 reclassified Empectocladus to Prunus resulting in the designation Prunus fasciculata (Torr.) A. Gray (subg. Emplectocladus), in which the desert shrubs become a subgenus.[14] In 1996 Jepson[8] defined a California variety with smooth leaves, punctata, in comparison to which Gray's species, with pubescent leaves, becomes the variety, fasciculata. Unfortunately, the binomial Prunus punctata was already used in 1878 to describe what is now known to be Prunus phaeosticta.[15] Prunus fasciculata punctata grows in the coastal ranges as well as in the desert.[3][16][17]
Middens from rodent activities such as those of the pack rat are a rich source of plant macrofossils from late Pleistocene habitats. At Point of Rocks in Nevada by 11,700 BP, desert shrubs such as desert almond had replaced Juniper and Joshua trees, indicating the onset of the modern desert.[18] Somewhat earlier, 17,000–14,000 BP, desert almond flourished in a mixed desert and woodland ecology on the Colorado Plateau.[19]
The species is native to the deserts of Arizona, California, Baja California, Nevada, and Utah.[20][6][21][22][23] It prefers sandy or rocky soil on dry slopes and washes, usually below 7,000 feet (2,100 m) elevation.[20]
The plant is not cultivated. Some Native Americans in its limited range learned traditional ways of using it: the Cahuilla prepared the drupe as a delicacy. The wild almonds were considered a delicacy by Native Americans. The Kawaiisu found the tough twigs useful as drills in starting fires and as the front portion of arrow shafts.[24] The seed contains too much cyanide to be edible, although there is some archaeological evidence that the seeds were pounded into flour and leached to make it edible by the ancient population of the Mojave desert.[25]

Prunus fasciculata est un arbuste ornemental de la famille des Rosaceae, originaire des régions désertiques.
Il est utilisé comme arbuste ornemental autant pour ses fleurs, blanches, que pour ses fruits. Néanmoins, ces derniers sont impropres à la consommation car toxiques. Les fruits ont été utilisés comme source de nourriture par les Amérindiens.
