This stamp from Comoros (Union des Comores) issued in 2009 features the renowned French naturalist Michel Adanson (1727–1806), a pioneering botanist known for his contributions to plant classification. The design pairs his portrait with illustrations of the Parasol Mushroom (Macrolepiota procera), a species recognized for its tall stalk and umbrella-like cap. Adanson’s work helped shape early natural history and taxonomy studies in the 18th century. The stamp combines scientific heritage with botanical illustration, making it attractive to collectors interested in natural history themes. With its classic portrait style and detailed fungal drawings, it is a distinctive modern commemorative from Comoros.
