2019 USPS Cactus Flower Forever Stamps 100Pcs/Pack

Cactus Flowers celebrates the beauty of cactus flowers with a booklet of 20 stamps. Each stamp depicts a photograph of the flower of one of these ten cacti: Opuntia engelmannii, Rebutia minuscula, Echinocereus dasyacanthus, Echinocereus poselgeri, Echinocereus coccineus, Pelecyphora aselliformis, Parodia microsperma, Echinocactus horizonthalonius, Thelocactus heterochromus and Parodia scopa. Within the booklet, each stamp design is featured twice. With new DNA studies, botanists sometimes reclassify plants. As of the printing of these stamps, the scientific names were accurate. Cacti also have common names, with some plants having several different names in popular use. Art director Ethel Kessler designed the stamps with existing photographs taken by John P. Schaefer.
