Diaspores

Foxtail (Diaspore)

There are numerous types of seed dispersal methods within the plant kingdom. One such method is through a diaspore, a unit that consists of seed and additional tissue to help with dispersal. While these may be found with fruit, common in plants dispersed by frugivores, another commonly seen diaspore is known as foxtail, or spear grass. As the common name implies, it can be harmful, or even fatal, to livestock and pets due to its sharp structure. Foxtail itself refers to a number of grasses, some with a fanning structure and others with a cone shape. Control of foxtail is important in pastures.
