|discussion=<p>In the flora area, <i>Simmondsia chinensis</i> is native to arid areas of southern California and Arizona (despite its specific epithet, it is not native to China). It is very drought tolerant and able to withstand extreme daily temperature fluctuations. Its thick, leathery leaves are usually held erect, maximizing interception of solar radiation during the cooler part of the day and minimizing it during the heat of midday. Flowering and fruiting times are dependent on timing, duration, and intensity of the winter and spring rains, but generally flowers are at anthesis March to April and fruits mature about six months later. Flower buds are initiated during development of new leafy shoots in winter and generally remain dormant until early spring (or longer under drought conditions). Capsules may reach full size several months before the seeds mature and disperse.</p><!--
--><p><i>Simmondsia chinensis</i> is cultivated as a commercial crop in desert and semidesert areas (Australia, North and South America, and the Middle East) for its oil-rich seeds. Jojoba oil is an unusual liquid wax ester, more similar to whale oil than it is to most vegetable oils, and is used primarily in cosmetics. The evergreen foliage is important as year-round forage for livestock and wild animals, and the fruits are eaten by wild mammals and birds.</p>
