Hechtia pumila

Native to Guerrero in southwestern Mexico, this perennial bromeliad grows in seasonally dry tropical habitats. It forms a ground-level rosette with spine-edged leaves and sends flowering stalks above the foliage. Male and female flowers occur on separate plants. It grows on dry, rocky hills, including limestone slopes. In Guerrero, Mexico, it occurs between about 2,000 and 5,400 feet above sea level. Photographed in Florida.
