Issued in 1981, this attractive Rwanda commemorative set highlights the country’s rich botanical diversity through detailed illustrations of native flowering plants. The set features Pavonia urens (50c), Pavetta rwandensis (20c), and the elegant orchid Cyrtorchis praetermissa (30c), all rendered in soft, naturalistic tones. Designed by L. Dobon, these stamps combine scientific accuracy with artistic charm. A desirable thematic issue for collectors of botany, flowers, orchids, and African flora, and a fine example of Rwanda’s nature-themed philatelic output of the early 1980s.
