Island Cherry Trees
From Islapedia
Island cherry tree (Prunus ilicifolia ssp. lyonii), a tree in the rose family, is endemic to the California Channel Islands. Distribution is limited to Santa Rosa, Santa Cruz, Anacapa, Santa Catalina and San Clemente islands.
Raw pulp of the fruit is edible, and Native Americans processed the large pits, leaching out toxins, thus making them palatable.
