Issued by the Republic of Indonesia in 1966, this 30 + 10 sen semi-postal stamp beautifully depicts Ixora coccinea, known locally as “Soka.” The vivid orange blossoms of the tropical shrub are finely illustrated against a white background, capturing the species’ lush beauty. The additional 10 sen surcharge supported social or cultural causes, reflecting Indonesia’s post-independence philatelic commitment to both art and community welfare. A graceful emblem and elegant typography complete the design, making it a sought-after item for floral and Southeast Asian thematic collectors.
