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.

Description

Prunus fasciculata grows up to 2 metres (6+12 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 (1434 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 (12 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]

Taxonomy

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

... a top so densely branched, angled and interlocked as to well merit the name Emplectocladus (Greek, "woven branch"), signifying interlocked branches ...

According to George Bentham and Joseph Dalton Hooker [12] the name fasciculata means that the leaves are in fascicles, or little bundles:

Leaves small, spatulate, as it were of precious stones, subglobose fasciculate [13]

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]

Palaeobotanical evidence

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]

Distribution and habitat

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]

Uses

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 ancient population of the Mojave Desert pounded the seeds into flour and leached it to make it edible. [25]

<i>Prunus</i> Genus of trees and shrubs

Prunus is a genus of trees and shrubs in the flowering plant family Rosaceae that includes plums, cherries, peaches, nectarines, apricots, and almonds. The genus has a cosmopolitan distribution, being native to the North American temperate regions, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, There are about 340 accepted species as of March 2024. Many members of the genus are widely cultivated for their fruit and for decorative purposes. Prunus fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena. This shell encloses the seed, which is edible in some species, but poisonous in many others. Besides being eaten off the hand, most Prunus fruit are also commonly used in processing, such as jam production, canning, drying, and the seeds for roasting.
