So the next time you put a pinch of table salt on your favorite gourmet dish, think about the world's smallest fruits which are approximately the size of one salt grain. A tiny, budding Wolffia globosa plant and the minute one-seeded fruits of W. angusta compared with the eye of an ordinary sewing needle. The fruits are about 0.30 mm long. Fruits of W. angusta and W. globosa are similar in size and are the smallest fruits on earth. The brown, disk-shaped structures mixed with these populations of Wolffia columbiana and W. borealis in the San Dieguito River of San Diego County are not wolffia fruits.
