Loasa

The genus Loasa is part of the Loasaceae family, which primarily consists of tropical American plants known for their often striking, colorful flowers. Many species within this family, including those in the Loasa genus, possess stinging hairs that can cause discomfort. The flowers of Loasa species are distinct, featuring pouch-like petals and unique nectaries. While most Loasaceae are found in the Americas, a few species also grow in Africa, western Asia, and Polynesia. The genus Mentzelia, also in this family, has hooked hairs instead of stinging ones and features satiny, often orange blooms.12
