About Pseudoziziphus parryi (Torr.) Hauenschild
Pseudoziziphus parryi is a bushy shrub with many intricate branches that grow into a thorny tangle, and it can reach close to 4 metres (13 ft) in height. This species is deciduous; its leaves are absent for most of the year, leaving the shrub as a bare thicket of brown or grayish twigs. The tips of these twigs taper into sharp-pointed thorns. When present, the membranous olive green leaves grow up to 2.5 centimeters long. Its inflorescence is a small cluster of several yellowish or green-tinged, star-shaped flowers that each have five petals. The fruit it produces is a dry drupe that contains one single seed. Pseudoziziphus parryi is native to the Colorado Desert, the southern Mojave Desert, and the eastern slopes of the Peninsular Ranges, located in southern California and Baja California, Mexico. It grows in chaparral and Sonoran Desert habitats.
