This 2009 stamp from Comoros (Union des Comores) commemorates Italian Renaissance botanist Andrea Cesalpino (1519–1603), one of the earliest pioneers of plant classification. The design features Cesalpino’s portrait alongside an illustration of the mushroom Tricholoma flavovirens. Known for his influential botanical work De Plantis, Cesalpino helped lay the foundations of modern plant taxonomy. The stamp combines scientific heritage with natural history, making it appealing to both thematic collectors and botanically themed philatelists. Its detailed mushroom illustration also attracts collectors specializing in fungi and nature topics.
