Cactus Flowers Forever Stamps, 2019 Booklet – Greeting Cards and Letters

Cacti, seemingly simple plants, boast a wide variety of characteristics distinguishing each species. Factors such as spine type, growth pattern, and others determine the genus and species, emphasizing the stamp’s representation of cacti diversity. Interestingly, sometimes DNA testing becomes the sole method to differentiate two species.

This subspecies, among four with similar traits, features a ribbed surface with 8 to 11 sections and 5 to 20 spines per areole. Distinguished by its bright red-orange flower and a stem measuring one to two inches thick, it stands out amidst the variations in spines, stem thickness, flower color, and skin tone found in other subspecies.
