Have you ever seen a tree with milky sap? If so, you have likely met a member of the Mulberry family. These trees and shrubs have alternate leaves and milky latex sap. The unisexual flowers are small and usually tightly clustered, with male and female flowers appearing on the same or different trees. Male flowers have 4 (sometimes 0) sepals, 0 petals and 4 stamens. Female flowers have 4 (sometimes 0) sepals and 0 petals. The ovary is positioned superior or inferior and consists of usually 2 (rarely 3) united carpels, as indicated by the same number of styles. One carpel is usually aborted, forming a single chamber. In species with tightly clustered flowers, the fruits merge together as a single mass, creating a false fruit known as an "aggregate" or "multiple."
