Discussion
Myoporum laetum is commonly cultivated in coastal areas of California. Although first collected outside of cultivation in 1949, it was not recognized as an introduced element of local and regional floras until the 1970s. It has naturalized mostly in southern California to San Luis Obispo County with some populations north along the coast to the San Francisco Bay area.
Myoporum insulare R. Brown, also cultivated in California, is similar to M. laetum, and some reports of M. laetum are possibly M. insulare. Myoporum insulare has leaves that are lighter green when young, and the translucent glands of the mature leaves are less conspicuous. The flowers are slightly smaller with anthers that are only slightly exserted from the tubes, and the fruits are smaller and globular.
