This attractive Paraguayan semi-postal stamp features the Flor de Mburucuyá, the national passion flower (Passiflora caerulea), symbolizing natural heritage and cultural identity. Issued during the Centenary of the National Epic (1864–1870), the additional surcharge supported the monument dedicated to Marshal Francisco Solano López. The vibrant botanical illustration reflects Paraguay’s strong tradition of combining flora with historical commemoration. Its dual purpose—postal use and national fundraising—makes it especially appealing to thematic collectors of flowers, charity issues, and South American history. A colorful and meaningful addition to botanical or semi-postal collections.
