- Hairs: Stinging or glandular hairs on their stems and leaves.

- Flowers: Colorful and showy flowers, varying in color, including shades of yellow, orange, and red, often with an inferior ovary.
- Petals: Flowers in this family typically have five petals.
- Habit: Herbs, shrubs or trees.
- Ecological Diversity: Loasaceae plants inhabit a wide range of ecosystems, from deserts to temperate forests, and can be found in both North and South America.
- Spiral Inflorescence: The flowers of some species are arranged in a spiral pattern along the stem, creating an attractive inflorescence.
- Heterostyly: Some species in the Loasaceae family exhibit heterostyly, a reproductive mechanism where flowers with different lengths of styles and stamens are present in the same species. This promotes cross-pollination and increases genetic diversity.
- Cultural Uses: Certain members of the Loasaceae family have been used in traditional medicine for various purposes, such as treating skin conditions or respiratory ailments.
- Xerophytic Adaptations: Many species in this family have adaptations for surviving in arid environments, such as succulent leaves or deep root systems.
