Castela emoryi, with the common names crucifixion thorn, Emory's crucifixion-thorn, and Spanish : chaparro amargosa, [2] is a shrub species in the genus Castela of the family Simaroubaceae. [3]
The plant is native to the Mojave Desert and Sonoran Deserts of North America.
It is found in southern California, Arizona, and Sonora state (México). [3]
The species is dioecious and occurs in the moistest areas in the hottest, driest deserts within its range; it is considered poor in germination. [4]
Castela emoryi is often less than 1 metre (3.3 ft), and occasionally to grows 4 metres (13 ft) or more. [5]
Crucifixion thorn is mostly leafless, [6] [4] its sharp branches are green and perform photosynthesis. [7] Seeds are contained in clusters of fruit in groups of 5. The fruit is tan, green, red or brown in color, turning black with age. and may persist on the tree for several years. [8]
It is ranked on the California Native Plant Society Inventory of Rare and Endangered Plants, as an endangered species within California, and more common elsewhere. [9] It is threatened by solar energy development and military activities within its California range. [9] The species is classified as "Salvage restricted" in Arizona. [2] [10]
Castela emoryi is one of the few plants in its habitat that blooms in the mid-summer heat, and serves as an important source of resources for insects during that time. Its nectar is collected by ants, and pollination is performed by wasps and bees, [2] particularly bumblebees. [11]
The Yavapai people traditionally used this as a medicinal plant, making a dermatological aid from its bud's sap. [12]
Castela emoryi is a plant toxin insecticide. It contains quassinoids such as glaucarubolone glucoside which has antifeedant properties against termites such as Reticulitermes flavipes , [13] or potential fungicidal activity for the control of grape downy mildew. [14]
It also contains glaucarubol, a compound characteristic of the family, ellagic acid, betulin and (—)-syringaresinol. [15]
Parthenium argentatum, commonly known as the guayule, is a perennial woody shrub in the family Asteraceae that is native to the rangeland area of the Chihuahuan Desert; including the southwestern United States and northern Mexico. It was first documented by J.M. Bigelow in 1852 through the Mexican Boundary Survey and was first described by Asa Gray. Natural rubber, ethanol, non-toxic adhesives, and other specialty chemicals can be extracted from guayule. An alternative source of latex that is hypoallergenic, unlike the normal Hevea rubber, can also be extracted. While Castilla elastica was the most widely used rubber source of Mesoamericans in pre-Columbian times, guayule was also used, though less frequently. The name "guayule" derives from the Nahuatl word ulli/olli, "rubber".
Bergerocactus emoryi is a species of cactus, known commonly as the golden-spined cereus, golden snake cactus, velvet cactus or golden club cactus. It is a relatively small cactus, but it can form dense thickets or colonies, with the dense yellow spines giving off a velvety appearance when backlit by the sun. From April to May, yellow, green-tinged flowers emerge, which transform into reddish, globular fruit. This species is native to the California Floristic Province, and is found in northwestern Baja California and a small part of California, in San Diego County and on the southern Channel Islands. Where the Mediterranean climate of the California Floristic Province collides with the subtropical Sonoran Desert near El Rosario, hybrids with two other species of cacti are found. It is the sole member of the monotypic genus Bergerocactus, named after German botanist Alwin Berger.
