Summary Author: Christos Kotsaftis
Shown above is an elongated strand of a sap-like substance that's hanging from a lemon tree. This condition is known as gummosis -- the formation of a gummy material on the surface of certain plants, particularly fruit trees. The oozing from a wound or canker is a reaction to disease, infections, insects, storm damage, etc. Note that the fluid is refracting light from the lemon tree's leaves, seen in the background. Photo taken near Chania, Crete, Greece, on May 10, 2016.
