General: Anderson's Desert-thorn (Lycium andersonii), also called Anderson's Wolfberry and Water Jacket, is a stout, upright shrub with many tiny leaves and stiff thorns at the tip of each little stem. These shrubs are deciduous, quickly loosing their leaves as the summer heats up.

Anderson's Desert-thorn is glabrous (hairless), including the leaves and floral parts. The leaves usually are short and fleshy, but they can be longer and thinner. The flower tube is long, but the flower lobes are short, and the calyx also is short.

Anderson's Desert-thorn is a common component of vegetation communities in drier areas along washes, on bajadas, and into the lower mountains in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub) life zones.
