What characteristic is commonly associated with spurges from the Euphorbiaceae family?

The characteristic commonly associated with spurges from the Euphorbiaceae family is milky sap. This milky latex is a distinctive feature of many plants within this family and serves as a defense mechanism against herbivores. The sap contains various compounds, including alkaloids and terpenes, that can be toxic or irritating. This milky sap can deter animals and insects from feeding on the plants. In addition to providing protection from herbivores, the presence of milky sap can also play a role in the plant's overall health and resilience by potentially limiting certain pathogens or pests that could harm the plant.

While thorns, pungent odor, and ferocious growth might be associated with other plant families or specific plant traits, they are not defining characteristics of spurges in the Euphorbiaceae family, highlighting the uniqueness of milky sap in their identification and ecological adaptability.
