Willow (Salix sp.) pollen grain, illustration

---

Illustration of a pollen grain of a willow tree (Salix sp.). Each grain has an elongated form with rounded ends and a grooved and pitted surface. The willow tree flowers early in the year before its leaves appear. The pollen is a strong allergen and can cause allergic reactions such as rhinitis and hay fever, with some people developing asthma-like symptoms.
