This attractive pair of definitive flower stamps from Australia highlights native botanical species celebrated in the country’s long-running floral series. The 6c stamp features the striking Kangaroo Paw, recognizable for its claw-shaped blossoms and vibrant red stems, while the 13c stamp displays the delicate Pink Heath, Victoria’s floral emblem, shown in dense clusters of soft pink blooms. Designed by noted artists N. Wilson and R. & P. Warner, these issues reflect the refined mid-20th-century Australian definitive style, combining botanical accuracy with bold color composition. Such flower definitives are widely collected both by thematic flora collectors and by specialists building comprehensive Australian definitive series. Well-centered examples like this pair are ideal additions to native plant or Commonwealth collections.
